Lucas B. Kruijswijk's DATC
http://web.inter.nl.net/users/L.B.Kruijswijk

Hi Lucas,

Your DATC is a great document. I find enjoyment in looking through
it and reading the different and creative test cases you have come up
with.

First Topic
-----------

In one post, you said:
QUOTE
In the DATC. The first bug is in test case 6.E.7. This is a bug in the
DPTG, that has been known for a long time. The second bug is rather
similar. It is the same case but combined with a circular movement.
If you correct the DPTG for the first bug, the same situation will
still go wrong when it is combined with a circular movement.

The third bug is really different. The DPTG fails on test case 6.E.15.
In this case the DPTG is not deterministic. It depends on which orders
you start, so that is clearly wrong.
UNQUOTE

So, I take it that the second bug as described above does not yet
have an official DATC test case.

Second Topic
------------

I believe that I disagree with your results for test case 6.E.15.
Please be patient if I have missed something obvious; obviously,
if I have made a beginner's mistake, then please consider this a
learning experience for me.

In the following scenario, the DATC asserts that the head to head
battle between Kiel and Berline prevents that either unit involved
in this head to head battle is dislodged. I, though I am a beginner,
find that I do not agree with this interpretation.

Scenario: Test Case 6.E.15:
England:
F Holland Supports A Ruhr - Kiel
A Ruhr - Kiel

France:
A Kiel - Berlin
A Munich Supports A Kiel - Berlin
A Silesia Supports A Kiel - Berlin

Germany:
A Berlin - Kiel
F Denmark Supports A Berlin - Kiel
F Helgoland Bight Supports A Berlin - Kiel

Russia:
F Baltic Sea Supports A Prussia - Berlin
A Prussia - Berlin

Written, human-being based adjudication procedure (though the same
results would
be obtained using the "Perfect Adjudication Engine (once it has been
perfected!) and using the tools called the Hot Spot indicator and the
stacked,
ordered to-do list):
The first hot spots to
consider are Kiel and Berlin. Both the French and the Germans are in a
head-to-head battle each having equal strength of three. Therefore,
the
movement of the French from Kiel to Berlin fails and the French army in
Kiel now holds in Kiel, similarly, the German army attempting to move
from Berlin to Kiel, bounces, and thus is now holding in Berlin.

This resolves the hot spots in Kiel and Berlin with respect to the
head-to-head
battle between the French and the Germans.

However, during the adjudication process, the next hot spots to light
up are
again Kiel and Berlin but for different reasons (those different
reasons being
that now the French army in Kiel is holding and now the German army in
Berlin
is holding). Because the British attack
into Kiel is supported, the French in Kiel are dislodged and the
British move
in; similarly, because the Russian attack into Berlin is supported,
the Germans
in Berlin are dislodged and the Russians move in.

Final adjudicated result: The French army in Kiel is dislodged; the
German
army in Berlin is dislodged; The British army in Ruhr moves to Kiel;
the
Russian army in Prussia moves to Berlin. No other units move.

The above adjudicated results vary significantly from what the DATC
says are
the adjudicated results (assuming that I have read and interpreted the
DATC
correctly), for the DATC says that the results are:
"None of the moves succeeds."

Explanation: The British attack into Kiel is not an example of a
"traffic jam."
It would be a "traffic jam" if the British were not supported. If the
British
were not supported into Kiel their movement to Kiel would fail. But
since
the British are indeed supported, the attack by the British succeeds.
Thanks

Hi,

Please also see the year 2000, fourth edition
rule book: Diagram 12.

In Diagram 12, the German army in Munich
failed to successfully attack and move into
Silesia. Nevertheless, this German army
in Munich did not create a "traffic jam"
and was dislodged due to the supported
Austrian army moving from Bohemia into
Munich with a total strength of two.

Thanks

Hi Lucas. Thanks for your responses so far. The above
states a double negative, which is harder to understand.
If you can restate it, then I can more accurately understand
your position.

NOW I SEE! Thanks for presenting your concept here!
I would never have seen this. It is very subtle. You are
saying that somewhere in the adjudication process, the
army in Kiel moving to Berlin (with a strength of 3)
also stopped the movement of the army from Prussia
to Berlin which had a strength of 2.

Very interesting!

I'm not saying that I agree or dis-agree with you at this
time; but, I am very glad that I understand your point
of view.

Here is another interesting twist to add to the above
scenario as I think about it: What would be the differences
in adjudication if the army in Kiel had been ordered
to Berlin via convoy? How does this inform or fail to
inform our thinking processes on this issue?

But, concerning your main point which you say that the
Diplomacy community as a whole agrees with you on,
I don't yet have an opinion (having just read your post).
My first step will be to try to find a similar scenario in
the rule book.

Thanks much, Lucas. Again, your DATC is a great resource.

Hi,

Thank you all for taking the time to
give your personal comments on the
scenario. This makes it even easier
for me to understand your point of
view, for each explanation has its
own coloring which makes the
learning task easier.

Thanks

Hi,

when the twice-supported German army fails? It can't.
UNQUOTE

Hello Randy and everyone,

It is unfortunate that perhaps, as it will depend on my future study
and
analysis of this position, it appears that I might end up in the
minority
opinion. That is, I hope that the discussion won't get overly heated.

Please, everyone, keeping in mind that I will have to go over the
manual, go over the examples, and again read over everyone's inputs,
please do not assume that I have made up my mind one way or
the other, or that I have simply refused to consider your majority
opinion.

I am about to begin my analysis (or instead, I may go watch the
football game, I haven't decided yet).

But, here is a preliminary thought which came into my head in
response to Randy Hudson's comment above; a thought which
did not initially occur to me when I was being influenced and
almost persuaded by his argument.

It is this: I have not set up my map yet, so I forget where
all the units are, but basically, you have two military
units, each supported twice, MOVING into EACH OTHER'S
territory.

So, it is important to recognize, at least as part of a
preliminary analysis, that when I said the English
moved in with a strength of 2 and dislodged whoever
was there, keep in mind that whoever was there
had no defensive supports! The army that
the English dislodged had offensive supports into,
what, Berlin was it.

So, I think there is something here to be considered
in my initial idea.

At the same time,
I can see how Randy's idea makes sense also!
How can the British with a force of only 2 dislodge
whoever was there when the German army with
a force of 3 bounced. This also rings true to me.

But then I see the Germans with a force of three
bouncing off another force of three, and that
other attacking force
have "their backs to the attacking" British. So, in
this context, a force of 2 by the British may be
sufficient to dislodge. That is, the British never
engaged the Germans--this rings true to me,
because the Germans never left Berlin.

This whole thing sort of reminds me of a figure of a box, and when
you look at it, you can visualize whichever end of
the three dimensional box you consider closest to you.
And, as you look at it, sometimes which side is
considered closest to you changes.

That is sort of how I feel at this moment. Sometimes
my initial analysis makes sense, sometimes the majority
opinion makes sense. So, I'm definitely undecided at
this time.

Maybe I will watch that football game!

Any way, I will have to analyze this and think about it.

I appreciate your opinions, and will have to think about
this very, very interesting situation that the DATC
has created: one among very many creative scenarios.

Thanks

Hi,

Here is the new scenario. I have changed the scenario so that there is
an
option for a convoy which may, perhaps, stimulate my thinking process.

Scenario 1:
France:
Army in Piemonte to Venezia.
Army in Tuscany supports Army in Piemonte to Venezia.
Italy:
Army in Trieste to Venezia.
Army in Roma supports Army in Trieste to Venezia.
Army in Apulia supports Army in Trieste to Venzia.
Fleet in Adriatic Sea holds.
Austria:
Army in Venezia to Trieste.
Army in Vienna supports Army in Venezia to Trieste.
Army in Budapest supports Army in Venezia to Trieste.
Turkey:
Army in Serbia to Trieste.
Army in Albania supports Army in Serbia to Trieste.

We should keep in mind that we are all reasonable people; thus, if we
actually
had hard facts in front of us, then presumably we would agree with each
other
completely. But, instead of hard facts, we have a rule book (or even
rule
books); and, apparently, since there exists a minority opinion
(presumably even
if I personally held the majority opinion), the rule book would then
not be
considered completely unambiguous, because the rule book left open the
possibility that a small minority might interpret it differently.

As long as there are no hard facts about, then my statements in this
article
can only be opinion. Let it be known that my opinion may represent a
very
small minority; let it also be known that it is not my intention to
attempt to
persuade anyone to accept my opinion.

I am essentially exploring this topic. It is like arguing about how
many angels
can dance on a head of a pin! Who can say, because we don't know how
big an
angel is: that is, we have no hard facts.

Nevertheless, even without hard facts, there can still exist, as there
does,
a common understanding among the majority about what exactly should be
what.
This is fine; this is called conventional wisdom or conventional
interpretation, and it is not to be ignored, but also considered. But,
in the
final analysis, unless there are sufficient facts, almost everything
is, one
could argue, personal preference and personal opinion. However, I do
not mean
to suggest that either the majority or minority point of view is
whimsy! Not
at all; I should instead say that the majority point of view is a
hard, true,
honest attempt to interpret the rules. I only use the term "opinion"
so that
my minority opinion will not be mis-understood as either gospel or as
an attempt
to suggest to others that they must adopt my point of view.

While I'm writing this article, which is an exploration, my point of
view may
change back and forth, or I may have no point of view. That is because
this is
the hardest issue yet I have ever faced when looking at a Diplomacy
board
scenario.

But, when the day is over, and I say that for Scenario 1, that the
French took
Venezia, that's how you'll know that I hold the minority opinion. But,
if at
the end of the day I say that no units moved, then you know that I hold
the
majority opinion.

Regardless of which opinion one ends up holding, it is very hard, for
me at
least, not to find this gem or Diplomacy scenario ripe for exploration
and fun.

******
Part 1
******

[With respect to DATC Test Case 6.E.15]

Your approach is to see things as a set of "head-to-head battles",
resolve these, and then look at what is left. But how do you decide
which head-to-head battles to look at first? On what basis would you
start with the Kiel-Berlin battle first? Why not look at the Kiel-Pru
battle first, with a different result?

Nick
--------------------------------------------------------------------------------

Nick makes a good point. Assuming that I make up rules for an
adjudication
algorithm, how do I know with certainty that my rules are appropriate
when they
decide in which order which provinces or battles will be adjudicated
first
during the adjudication process?

Basically, the answer is I don't know. What would happen is that if
the
adjudication worked for all known cases, then it would be accepted that
if you
follow its rules and regulations during the adjudication, the desired
result
is almost always found. But, in this case, my current algorithm for
adjudication clearly comes up with an adjudicated result held only by a
small
minority. Since there is no proof, nothing can be said. Clearly my
algorithm
will not be used as a perfect adjudicator (although, I might add that
it might
be found to be used as a general guideline, if it is found that it
works
most of the time; the beauty of the algorithm is that, in my opinion,
it is
fairly easy for a human to implement it in the human's head, but again,
it
would never be considered a perfect adjudicator for all positions,
because
Scenario 1 above proves that it holds a minority view).

The DATC will propose an adjudicator using the concept of simultaneous
equations; so, we will drop this discussion of algorithms for the
moment
and await what the DATC adds to this discussion.

******
Part 2
******

It is evidently hard to program simultaneity, but simultaneity is
crucial to
correct adjudication.

David E. Cohen
--------------------------------------------------------------------------------
This is the key issue for programming, I agree. The movement really
IS simultaneous. That is almost unique among games of complexity
greater than "rock/paper/scissors".

Jim-Bob
--------------------------------------------------------------------------------

Above are two responses, which I appreciate receiving, from two
distinguished
members of the Diplomacy community.

As a novice at Diplomacy, I respectfully raise the following topic.

This is, somewhat, I guess, "philosophical," but I am not introducing
it simply
to suggest that the universe can't be understood because there is a
black hole
somewhere in outer space. But, here goes: if that movement really is
simultaneous, then how is it that a unit can be given attack orders, be
bounced
back because this movement or attack failed, then have this unit
changed to
hold? In short, how can a unit attack and hold simultaneously? If a
unit
was allowed to attack and hold simultaneously, then why could not other
units
follow valid orders to support this attacking army to its attacked
location
AND support this attacking army in its original location in case it got
bounced
back?

Again, the above may be overly "philosophical," or perhaps down-right
silly when
read by an experienced Diplomacy player; but, as the thoughts did
enter
my head, I thought I'd write them down; perhaps I will find them silly
when
I read them the next day, or the next month: afterall, novices do
change
their minds as they gain more experience.

A very valid respond to my "silly" philosophy, is this, and its an
argument
that I personally would have no hesitation in using in other scenarios:
please
don't bother me with descriptive text of how the army made dinner, told
jokes,
held, and so forth; if you want to discuss rules, fine, but don't add
details
which are not part of the game.

Another way of saying the above "silly" philosophy is this: I'm pretty
sure
that somewhere on the internet I have read that the game creator
considers the
movement simultaneous in the sense that each movement unfolds in six
months.
This would, indeed, allow a unit to attack, be bounced back, change to
a hold,
and then repulse an attack that had been launched against it.

However, I am not suggesting that we can only adopt this belief if the
game
creator suggested it; even if the game creator did not suggest this
idea, we
can, if we so choose, consider it for adoption (assuming that "we" is
those
members holding the minority view point).

This does allow, then, perhaps, the majority view and the minority view
both
to offer some validity for their views.

Majority view: the movement is purely simultaneous.

Minority view: the movement is a representation of simultaneous
movement over
a six month period, thus it could be called "fuzzy simultaneity,"
giving the
minority view a new chance at validity. This gives the minority view
more
validity, because the minority can say: within a six month period, the
following happened: The Austrian army fought on the eastern front and
was
bounced back to its original location in Venezia; after the Austrian
army
bounced back to Venezia, they created a defensive formation, but were
unable
to hold their position and were thus dislodged by the advancing French
army
from Piemonte. It is interesting to note that the minority view allows
for
a "perfect algorithm" to simulate this "fuzzy simultaneity. But, as
mentioned
above, the DATC may propose an algorithm that will work for the
majority view
of perfect, pure simultaneous movement.

******
Part 3
******
[With respect to DATC Test Case 6.E.15]

Each such movement is opposed by a superior force. By erroneously
converting
the superior force movements to "Hold," you've lost their effect of
opposing
equally or less supported attempts to enter the same province.

....

That's just wrong. How can a once-supported English army move into Kiel
when the twice-supported German army fails? It can't.

Randy Hudson
--------------------------------------------------------------------------------

Randy's comments are very persuasive. In almost any other scenario, I
would
readily agree with him, as would most people. That is why DATC Test
Case
6.E.15 is so fascinating! It merges common, intuitive concepts into
one
complex of fuzzy ambiguity, resulting in a split of opinion among
rational
people wherein the majority view takes one stance and the minority view
takes
another.

By the way, this article will use Scenario 1 given above, and not DATC
Test Case
6.E.15, though the two scenarios are functionally identical.

******
Part 4
******

As I write this article, and as I think ahead of examples and
exploratory paths,
I must be honest, I guess, and state that at this time my personal
opinion is
now that of the minority. By stating this now, I don't given the false
impression that I am undecided, and exploring with no opinion
whatsoever.
However, even though I can think ahead and believe I know what my
opinion will
be, nevertheless, it is always possible that I will stumble upon some
scenario
which will change my mind. So, although I have an opinion, or a
working
hypothesis, I hope that I also have an open mind.

I think that I can phrase the situation which splits the majority and
the
minority camps: I think it is this in a nut-shell: does the game
dynamic
or the movement dynamcis change based upon the presence of an army
within a
contested region, or based upon the orders given to an army present
within the
contested region?

In Scenario 1, I think that captures what splits the two parties: the
majority
view and the minority view.

Exploration 1:
Create Scenario 1 on your Diplomacy board.
Remove the Austrian army from Venezia and pretend it is not part of the
game.
What happens in Venezia?

It is clear, right? We all agree: the Italians with a force of 3 move
into
Venezia from Trieste overcoming the French ambitions in that province
which
only had a strength of 2.

Exploration 2:
Create Scenario 1 on your Diplomacy board.
Change the Austrian army in Venezia to this order: hold.
What happens in Venezia?

Well, again it's clear. The Austrian army in Venezia is dislodged, and
using
the same logic as given just above, the Italians move in to Venezia
from
Trieste.

So far, the Austrian army in Venezia, or lack thereof, has not changed
the
outcome of our two explorations so far in that the Italians moved from
Trieste into Venezia.

Exploration 3:
Create Scenario 1 on your Diplomacy board.
Remove the French armies from the game and pretend they do not exist.
What happens in Venezia?

Again, we all agree. The Austrain army fails to move to Trieste and is
bounced
back to Venezia. In particular, the Italian army in Trieste, this time
failed
to move into Venezia.

Okay, enough exploratory examples; as far as I can tell, they cannot
be used
to demonstrate any type of proof. But, I hope the exploratory
examples, and
others that you can make up yourself, do show that the presence or
absence of
the Austrian army in Venezia, as well as the particular orders this
army is
given, has a profound effect upon what happens in Venezia.

If we know that the presence or absence of the Austrian army in
Venezia, as
well as the orders this army is given, have a profound effect on what
happens
in Venezia, can this state be leveraged to help either the majority
view or
the minority view?

I don't think so. All we can do is say that the majority view and the
minority
view differ as to EXACTLY WHICH EFFECT the Austrian army in Venezia
has, given
its orders, in Scenario 1 given above.

In particular, the minority view might argue this: The Austrian army
engaged
the Italian army at the border of Venezia and Trieste; the Austrian
army
bounced back to Venezia, held, and then was overcome by the French army
attacking with a force of 2 from Piemonte. But, this is not really an
argument, it is simply defining "EXACTLY WHICH EFFECT" the minority
view thinks
the Austrian army in Venezia had upon the final outcome. It is only an
opinion,
and a minority opinion at that!

That's all. To me, in my personal opinion, I like the minority view;
but, as I gain more experience, I, like any novice, may change my
opinion.

Thanks

If in a head to head battle, the unit is not dislodged,
then it can still prevent another unit to go to the
place it attacked.

See diagram 14 in the rules. This situation explains the
opposite, but from this explanation one might conclude
that when the unit is not dislodged, such prevention is
possible.

So, it is incorrect to resolve the head to head battle
and then say that this battle is over and that the units
used their power. They are still there, have still power
and can prevent other units to go the place. This is not
disputed in the Diplomacy community.

So, the army in Kiel (not dislodged), prevents that the
army in Prussia goes to Berlin.

The rules do not have a 'sequence'. Introducing such in
an algorithm is very cumbersome. The modern adjudicators
use decision based algorithms and as far as I know that
are the only implementations that are fully correct (although
you might dispute some interpretations of the rules, of
course). I do not know of any sequence based algorithm that
is fully correct.

So, your hot spot indicator and to do list, is an attempt
which any programmer that starts with Diplomacy would do
(or something similar), but it is not the way to go, to
my opinion. It creates similar bugs as in the DPTG.

The rules are more a set of equations. In the next update
of the DATC, I will make this more clear. In the current
version the algorithm and the mathematical description are
not fully separated.

The second DPTG bug is in the DATC. It is one of the cases
after 6.E.7, but I don't which one exactly.

It is evidently hard to program simultaneity, but simultaneity is crucial to
correct adjudication.

No, they're not holding, at least not as that term is used in the rules.

Each such movement is opposed by a superior force. By erroneously converting
the superior force movements to "Hold," you've lost their effect of opposing
equally or less supported attempts to enter the same province.

That's just wrong. How can a once-supported English army move into Kiel
when the twice-supported German army fails? It can't.

> the DATC says that the results are: "None of the moves succeeds."

That's a correct adjudication.

I don't see this as subtle. If one unit is trying to go somewhere with
a force of three, and another unit is trying to go there with a force of
two, then no way is the latter ever going to succeed.

Your approach is to see things as a set of "head-to-head battles",
resolve these, and then look at what is left. But how do you decide
which head-to-head battles to look at first? On what basis would you
start with the Kiel-Berlin battle first? Why not look at the Kiel-Pru
battle first, with a different result?

Heated discussions concerning rules ambiguities (whether real or perceived)
in Diplomacy? Not a chance. ROTFL!


P.S. I think you might find interesting the message archives of the
yahoogroup I was involved in, which was formed to "fix" the DPTG, and create
a "Rulebook Companion" to fix all of the contradictions, omissions and
ambiguities in the rules. Sadly, we got most of the way through things, and
it crashed over the issue of paradoxes.

Hi,

I have one small addition to make to my article. I'm not sure
what form of logical "argumenation" label would be associated
with it. I'm not even sure that it would convince me in a real
world where things were provable; but, in a game world where
things are not so easily provable, it might very well sway me.

As some of you know, my so-called "Perfect Adjudication Engine"
is in an in complete state: for instance, I have not yet considered
how it would handle "broadly general" orders. So, let's assume
that everyone plays diplomacy using strict convoy orders.

Now, come some big assumptions, for I have hardly had the time
to go through every scenario in the DATC. But, let's just make a
fun assumption: Assume that my "Perfect Adjudication Engine"
performed perfectly and gave the exact answers that the DATC
wanted for 99 out of 100 cases,but only failed on the DATC issue
that this article touches upon.

Who might be swayed by this, and why? Again, in a real world
where everything is presumably provable, it would be stated
that the model or algorithm is not yet mature and complete.
But in a game world, it could result in some, and I might very
well be one of these people, concluding that maybe I was
looking at this DATC issue "incorrectly;" because, the algorithm
uses a constant way of adjudicating everything it sees,
therefore, in this 1 out of a 100 case, maybe it is looking at it
correctly, and I as a human am not.

Just a thought or concept. Again, I'm not trying to convince.
I just thought it was a neat idea that sometimes a computer
algorithm can inform its creator of something the creator
had not considered. For instance, have you ever been
beaten by a three-dimensional tic-tac-toe playing computer?
And in being beaten, didn't the computer find scenarios and
positions you had never seen before, or tactics you hadn't
considered. It is along these lines that I speak about this idea.
Thanks

This is the key issue for programming, I agree. The movement really
IS simultaneous. That is almost unique among games of complexity
greater than "rock/paper/scissors". So stated intending to troll....
I'm curious what people might think the most popular complex
simultaneous movement game is, if not Diplomacy.

Hi Randy, The fleet is not convoying, it is holding, and thus has no
effect on
the particular scenario at hand; what I mean is that the fleet is
there so that
if we play "what if" games with the scenario, and want to introduce a
convoy,
the fleet is there to have its orders changed.

I'm exploring this topic; though, it is true that I have my own
opinion. One
aspect of this topic that we can explore, and that I'd like to explore
is
this: what rules are governing this particular scenario.

Keep in mind, please, that I'm not presenting my view point as a
gospel.

The first exciting aspect of this is why there are two opinions.
Exactly
which rule or rules are we looking at differently. This would be a
good
place to start, but I'm not sure, reallly, which rule or rules we are
looking
at differently. What I think is exciting is that we would probably
agree
with each other 99% of the time concerning other scenarios or
positions, but when we get to this position, the
rules we have been using all along, don't unamimously convince us
anymore.

I am not writing to gospelize. Though you are correct. Do I know
which
rule or rules pretain to the scenario under discussion and which rule
or rules bear upon this scenario and convince me one way or
another? I'm not sure I do. Do you know which rule or
rules convince you; if so, please state them, because they are a valid
and very important part of the discussion. Similarly, your opinion as
to
which rule or rules I'm ignoring in this particular scenario, is also
very important.

I agree with you. My comments were related to "philosophy" of pure,
simultaneous movement. It's not that I don't personally understand

Okay, what you say in the paragraph just above is very important. As
it
uses a game rule to decide. "The rules are explicit that the effect of
such a move on the space it is attempting to move to is nullified
*if the unit is dislodged by a move from that space*."
Then you say, also equally important, "Thus, it is not nullified by a
bounce at that space."

So, let's take Figure 13 or 14 in the year 2000, fourth edition rule
book.
What if that power wasn't dislodged? The reason that the army furthest
north would not move south is that it would be in a traffic jam with
the army already in its location.

I'm not saying that you are wrong. I am making my first suggestion
that the arguments over Figures 13 and 14 may not be correctly
extrapolated. I am not saying that I know this with any kind of
certainty.
I would like to explore these figures further, and the logic that you
all are extrapolating from what does not occur in these figures.

In other words, we know that the many members of the Diplomacy
community are highly intelligent and logical. Let me take the
role of "student" here. And, please walk me through the steps,
so that I completely understand how Figures 13 and 14 bear
on the scenario at hand.

I have not yet had a chance to re-read your comments, get the board

I don't see any unit ordered to convoy here. Did you mean Adr to be ordered
to convoy? As ordered here, the result is the same as before; 3-on-3
bounces between Ven and Tri, and bounces for Pie and Ser due to superior
force.

If Adr were ordered to convoy Tri-Ven (or vice-versa), then the Tri-Ven and
Ven-Tri orders wuld both succeed, and Ser and Pie would still both fail.

If Adr were ordered to support Tri-Ven, then that move succeeds, 4-on-3;
Ven-Tri is defeated by superior force, fails, and Ven is dislodged; Ser-Tri
succeeds (as Ven is dislodged by a unit coming from Tri, its move does not
have any effect on Tri, so Ser is moving 2-on-0). Pie-Ven fails, 2-on-4.

I'm not aware of any minority opinion on this one. Nor, apparently, is
Lucas; his DATC documents cases where there is divergence of opinion. In
this case, though the DPTG generates a different outcome, that's not noted
as a controversy but as an error.

If you think the commonly accepted adjudication is wrong, this is a good
place to argue that. Just stating your opinion without evidence won't have
much effect, however. If you accept the principle that the rules should be
deterministic, and there is exactly one correct adjudication for a set of
orders, then we should all try to make sure we agree on what that
adjudication should be in this case. I believe I know what that is, but I'm
able to change my mind if there's a good reason.

Which is why the discussion of that matter at the Diet of Worms was
important: not the literal answer to the number of angels, but the analysis
of what facts were known about angels, and how those facts should be
interpreted.

Or perhaps you'll share with us the evidence that convinced you that the
French take Venezia, and convince us, and we'll all hold the majority
opinion.

But, at end of day, this is just a game, and it plays best if we all agree
on the rules, and their interpretation. So, even if you feel that it's
unrealistic for a bouncing unit to still be able to repel a force invading
the same territory, once you decide that the other players in your game (or
the master, if you have one) take that as correct, you would be reckless to
not play as though that would be the adjudication.

> how is it that a unit can be given attack orders, be bounced back because

It isn't changed to hold. A unit which bounces, remains in place unless t
is dislodged, but it does not hold. It cannot be supported in place, for
example, while units not ordered to move can be.

Units often have multiple effects within the same turn. A unit can cut a
support yet bounce an attempted move from elsewhere. Or, it can cut a
support, be dislodged, and move during the retreat phase. A fleet can
convoy an army while also standing off an attack.

But in the position above, the weakly supported move Pie-Ven is bounced, not
by the unit which remains in Venice, but by the superior force of the attack
on Venice from Trieste. The rules are explicit that the effect of such a
move on the space it is attempting to move to is nullified *if the unit is
dislodged by a move from that space*. Thus, it is not nullified by a bounce
at that space. That seems to clearly cover the situation. Arguing that it
isn't the way real armies work isn't convincing; this is a game, and there
are many unrealistic features.

It depends on the orders given to all the units. But you're still
misunderstanding the bounce, I think.

Let's make a few small changes to your scenario 1).

First, take away Rome. Now, if we left things there, Venice would succeed
in its force-three attack on Trieste, though it is opposed by both the
force-two attack from Trieste and by the force-two attack on Trieste from
Serbia. The forces don't combine, however unrealistic that may be. In the
wake of the move, Piedmont would succeed in moving into Venice, of course.

Next, have Adriatic support Serbia's move: Adr s Ser-Tri. Now, the Ven-Tri
move bounces, because it is opposed by an equally supported attack on
Trieste, coming from Serbia. The bounce has nothing to do with Trieste's
own orders; it is the opposing forces which bounce each other. So, what
about Pie-Ven? Well, Tri-Ven isn't cancelled just because the move fails;
and Tri wasn't dislodged by the move from Ven, so its effect on Ven is
unaltered: it bounces the move from Pie.

Finally, take away Apulia. Ser and Ven, each twice-supported, still bounce
over Trieste without dislodging it, though it doesn't have any support
itself. But now, there is not enough support for Trieste's move to Venice
to bounce Piedmont's supported move to Venice. Venice, bounced in its
attempt to move to Trieste by the equally-supported Ser-Tri, is dislodged by
the once-supported Pie-Ven.

Thus, the bounce you object to has nothing to do with Venice's support for
its move, but rather was due to Trieste's opposing move to Venice with
superior force.

I agree. But, I can't say with certainty that I agree with the
mechanics
or our reasoning of what happened. It is always possible that two
people
have different adjudication mechanics which result in an adjudication
which is identical except for that 1 out of 100th scenario. Note that
in
your new "what if" scenario here, it DOES NOT matter with respect to
the final result that your adjudication reasoning and mine our
different:
to be consistent, let us assume that my adjudication reasoning is:
the Army in Venezia moves into Triest with a force of 3 to 2; the
Austrain army now in Venezia is not dislodged because this attack
is supported with a total strength of 3 against the Italian 2; in a
certain sense, the Italians in Trieste are not overly relevant since
they only have a power of 2 for attack into Venezia, and only a
holding power of 1 in Trieste. Once the Italians are out of the
picture (yes, I know that this adjudication process is not purely
simultaneous, of course), the Austrians from Venezia are still
"entering" Trieste being challanged by the attacking Turks who
also are attempting to enter into Trieste. The Austrian attack
into Trieste is stronger by 3 to 2, thus the Austrians from
Venezia enter Trieste.

Note that our adjudication reasoning differs, but our results
our the same. In the above 'what if' scenario you presented,
I often reason about it "purely simultaneously" just like you
do, because sometimes
it is faster, and often (almost always?) these two ways of
adjucational reasoning yield identical results.

I take it Roma is still out of the picture and there is no army there.
Le't also say that the fleet in the Adriatic is Turkish.

I agree.

In this scenario, Triestes orders are not very relevant and are
inconsequential due to the over-powering forces in the neighborhood.

Okay, to make sure we are on the same example, here is the "what if"
scenario that the above text refers to:
What if:
France:
Army in Piemonte to Venezia.
Army in Tuscany supports Army in Piemonte to Venezia.
Italy:
Army in Trieste to Venezia.
Army in Apulia supports Army in Trieste to Venezia.
Austria:
Army in Venezia to Trieste.
Army in Vienna supports Army in Venezia to Trieste.
Army in Budapest supports Army in Venezia to Trieste.
Turkey:
Army in Serbia to Trieste.
Army in Albania supports Army in Serbia to Trieste.
Fleet in Adriatic Sea supports Army in Serbia to Trieste.

And, the same question holds: what happens in Venezia.

I like the richness of your "what if" scenario I have detailed
above. I can see in my head everything unfolding
in pure simultaneity and, of course, under this form of
adjudicational reasoning, no unit would move. And,
to see your point, under this form of reasoning, the minority
view should particularly note that the Italian army in Trieste
did have an influence in Venezia in keeping the French
out of Venezia.

I might speculate, that if the minority view were to be consistent,
it would say that the French did dislodge the Austrian's from
Venezia. In effect, the minority view might say that the Italians
in Trieste never had any real effect in Venezia because they
could not "get past" the fast, hard, brick wall of a force of
three that was counter-attacking them. Any while its true
that the Austrians attacking from Venezia did not fail in their
attack due to Italians, their attack certainly failed due to the
Turks; so, Austrians can only muster a defensive holding
strength of 1 and are dislodged by the French attack.

So, let's modify you what if scenario slightly, and see if the
minority view runs into a contradiction.

Next What If:
France:
Army in Piemonte to Venezia.
Army in Tuscany supports Army in Piemonte to Venezia.
Italy:
Army in Trieste to Venezia.
Army in Apulia supports Army in Trieste to Venezia.
Austria:
Army in Venezia holds.
Army in Vienna supports holds.
Army in Budapest supports holds.
Turkey:
Army in Serbia to Trieste.
Army in Albania supports Army in Serbia to Trieste.
Fleet in Adriatic Sea supports Army in Serbia to Trieste.

the only change with respect to the previous what if scenario is that
the Austrian army in Venezia is holding, and the other two Austrian
units are out to lunch, holding, and not really related to this
scenario.

The minority view NOW would say that the Italians and the French
met in Venezia and bounced each other away, resulting in the
Austrian army in Venezia NOT being dislodged.

Also, given for completeness, the Italians in Trieste would be
dislodged
by the Turkish attacking force of 3.

In summary, the minority view is not saying much beside this:
the influence that a particular unit has on a province does
depend upon whether there exists another unit in that
province and what that unit's orders are. This is not a proof,
of course, but a mind set, or more particularly, a very
minority opinion.

Now, and this will have to be discussed in another thread,
it will be noted that I have been trying to "explain" the
"reasoning" of the minority view. But, really, this
"explanation" is attempting to come to terms with
the "fuzzy simultaneity" result that a sequence
based adjudication algorithm reaches. The question
is this, perhaps, can we find an example where the
"explaining" I have given and the "fuzzy simultaneity"
result of a sequenced based adjudication algorithm
breach! Such as DATC test cases 6.E.4 and
6.E.5. In these examples, the "fuzzy simultaneity"
algorithm matches the DATC results, but does the
"explanation" I have given of the minority viewpoint
breach from the underling algorithm? That would need
to be investigated.

Okay, so at this stage in this "what if" scenario, there is no unit

Unfortunately, I'm not sure what the "what if" scenario is
here any more, as my assumption of the "what if" scenario
under consideration does not seem to match your text
given just above.

For instance, the Austrian movement from Venezia moves
into Trieste with a force of 3, not 2, right?

Therefore, unfortunately, I believe that I don't have your
given 'what if' scenario set up on my Diplomacy board
correctly.

So that your text makes sense, let's also remove the unit in
Vienna. Okay, let's assume that the "what if" scenario you
are presenting is this: it is Scenario 1 with the following
units removed from the board: Roma, Apulia, Vienna,
and the Adriatic Sea.

Now indeed, the lone, Italian army in Trieste, even though
ordered to Venezia, is inconsequential. Whether the
adjudicator's mind uses a purely simultaneous algorithm
or a hot-spot-based fuzzy simultaneity algorithm, there
is no question that the Italians in Trieste have little
impact on the adjudication result. The real issue in
Trieste is the attacking Austrians with a force of 2
verse the attacking Turks with a force of 2.

I agree. The Austrians failed to successfully take Trieste, and this
same army is over-run by the attacking French; the French attack
Venezia with a force of 2 and the Austrian army in Venezia is
dislodged as its holding strength was only 1.

I'm not sure what bounce I object to; keep in mind that this is very
tricky because in 99 out of 100 adjudications, you and I will agree!
That is what is so interesting about this Scenario 1. When you
simplify Scenario 1, you and I agree 100 percent. Can we determine
what
aspects contribute to this break of opinion for this one particular
Scenario 1?

Now I will attempt to understand your conclusion. If I reason
incorrectly
about your conclusion, then please clarify. Obviously I want to be
exposed to your reasoning and make sure I am processing it correctly.

Now I have set up Scenario 1 again on my board. Now I read your
conclusion: "Thus, the bounce you object to has nothing to do
with Venice's support for its move, but rather was due to Trieste's
opposing move to Venice with superior force."

Unfortunately, I don't fully understand how to process your conclusion.
Please clarify, since I obviously would be missing something if I
don't at least understand your argument. I think part of the confusion
may be I'm not sure what the different phrases in the conclusion
are referring to, such as which scenario or "what if" scenario.
I suspect that your logic can be abstracted like this: in some "what
if"
scenario we see dynamic X at work, but in the Scenario 1 which
encompasses dynamic X, you argue that I am inconsistent in that
I then ignore dynamic X.

This is an important vein of argument and a good approach.
Unfortunately, I did not fully understand which dynamic X
I was allowing in the "what if" scenario and then disallowing
in the Scenario 1.

So, let me think a minute and see if I can figure it out myself.
Okay, let's set up Scenario 1 again on the playing board.
I think I understand your argument and will now attempt to
express it: The minority view is faulty in that it is inconsistent
in its evaluation of the effect of the Italian army moving into
Venezia from Trieste. The majority view holds that this is a
constant force of 3 ALWAYS. Yet, the minority view holds that
there do exist at least one example formation, such as Scenario 1,
where the strength and total effect of the Italian attack is
moderated by the orders given to and the counter-attacking
strength currently resident in Venezia. This results in what
the majority consider a very peculiar adjucation, wherein the
French with only a strength of 2 end up marching into
Venezia.
Thanks for your comments, Randy.

Hi,

In another article, I made a preliminary modification to
my adjudication algorithm. I will now apply it to this
scenario to see if it flushes out or to see if it the
algorithmic fix creates even more problems.

The minority view point has two parts:
1. The adjudication algorithm is a black box, there is
nothing which says that the black box inner workings
need to actually be pure, formal,simultaneous movement,
only that the result of the black box adjudication
represent seemingly simultaneous movement.
2. Can the minority view point be supported by
my repaired algorithm for this scenario?

Scenario 1:
France:
Army in Piemonte to Venezia.
Army in Tuscany supports Army in Piemonte to Venezia.
Italy:
Army in Trieste to Venezia.
Army in Roma supports Army in Trieste to Venezia.
Army in Apulia supports Army in Trieste to Venzia.
Fleet in Adriatic Sea holds.
Austria:
Army in Venezia to Trieste.
Army in Vienna supports Army in Venezia to Trieste.
Army in Budapest supports Army in Venezia to Trieste.
Turkey:
Army in Serbia to Trieste.
Army in Albania supports Army in Serbia to Trieste.

Using the new, repaired algorithm of mine, which
has been repaired to come up with a minority
opinion adjudication here are its processes.

The first and only hot spot to consider in adjudication
begins is Venezia and Trieste, where two armies
are attacking into each other, with equal strength
of 3; so, they bounce.

The Austrian army in Venezia is now "holding".
The Italian army in Trieste is now "holding".

The "holding" labels above allow two more hot
spots to now light up: again Venezia and Trieste,
but this time due to the attacking French and
the attacking Turks, respectively.

Bearing upon the outcome in Venezia is the
following: the Austrian army placing force
there of a hold of strength 1; the attacking
French with a strength of 2, and the attacking
Italians with a strength of 3.

We now ask what these attacking armies encountered
en route to their attacked destinations. The French
encountered no resistence, just the common "hold".
But, the Italians encountered a stiff counter-attack
by the Austrians of 3, and thus the Italians are
not considered to have influenced Venezia
significantly for this scenario (though, of course,
if Venezia had been given a support order, that
order would have been cut).

So, the French take Venezia, and the Austrians are
dislodged from Venezia.

It appears that the algorithmic fix did hold "true"
in representing the minority opinion for this
given scenario. Though, the reader should
be aware that the majority consider this rendition
either a minority opinion or just a plane, incorrect
adjudication result.

Note that I did not bother adjudicating the eastern
sector of this example, since it is symmetrical, and
similar reasoning could be used.

The next thing I'll need to do is check to see if
my new, enhanced algorithm directly contradicts
any adjudication results as given in the year 2000,
fourth edition rule book; for if there are any
direct contradictions as to the adjudication
results, then the minority view may find itself
on very shaky ground indeed.

Thanks

Hi Everyone,

Thank you all for thinking and offering your ideas.

Let me please remind new readers that my opinions
are definitely way-out, minority opinions and that
the majority would categorize them as just plane
incorrect.

I appreciate everyone responding to my off-beat
ideas and helping me, in the final analysis, until
I find something that contradicts my ideas, now
believe more strongly in my minority opinion
concept: that the adjudication algorithm is a black
box with no restrictions on how it does its job,
with no restrictions that it must think and
adjudicate in pure, simultaneous movement;
only that it produce results which are seemingly
simultaneous.

Thanks again!

Hi Jim,

I apologize. It is unclear in what phrase or paragraph or set of
paragraphs I wrote that misrepresented you. But, it is not my
intention to misrepresent you or anyone else.

You also say that you are of the "minority opinion" if I read
your post correctly. That's good! No one likes to be totally
alone. Since you seem far smarter than me, I suspect that
I can learn a lot from you.

I would be interested in understanding this a little more. But, I
may need a little help. First, I am interested in understanding it
because I would like to see what the "purest" adjudication
algorithm would produce.

I may be a little slow, so please be patient. I need to first
understand
where the number 34 came from. The number of provinces on the
Diplomacy map is greater than 34. The number of provinces that are
starred could be 34 (it is hard to count them without losing my place,
but since it takes 18 of this starred provinces to win, then 17 is
probably the half-way point, and that would be 34 total starred
provinces).
Okay, I'll try to count the starred provinces again: 32 (but I may
have
missed a couple).

So, let's assume there are 34 starred provinces, but that wouldn't
enter into the equations, I suspect, that is, it would not dictate--
oh, I take that back, because the number of starred provinces
is how many military units in total can exist on the board!

Okay, finally, I have finally counted 34 provinces. At most, there
can be 34 military units on the field. But, fortunately for us,
there can be two, or three, or some small number so that we can
explore your ideas further and perhaps more easily than if we
had 34 simultaneous equations, and I can learn from your ideas.

Now, we have to be careful, however. Part of your post was saying
that in actuality, the instantiation of the adjudication engine might
use short-cuts, so as not to actually perform the solutions to all
the equations.

With your cooperation, I would like to explore a very simple scenario,
set up the simultaneous equations, and give it a run through.

Once I get the hang of it, presumably I could manufacture more
complicated scenarios and then figure things out without your
help. But, at this stage, I have no idea particularly how to begin.

Here is the first simple scenario:
Scenario 1:
French Army in Marseilles to Piemonte.

That's it, and presumably that is "one equation." At this stage,
you may say, "okay 'stupid,' I didn't literally mean equations."
So, by making an example, I can find out what you really meant,
and if there really is an equation per say, and if so, what that
equation might look like.

Here is the second scenario:
Scenario 2:
French Army in Marseilles to Piemonte.
French Army in Spain to Marseilles.

This could be a rather complicated equation, as it would seem
to involve 'spatial relationships.' That is, the army in Spain
needs to know that it can only move to Marseilles if Marseilles
ultimately is left empty by the army originally there.

I think these two simple examples are enough for me to learn
about. I'm beginning to think that how this would be done is
not purely by equations, but would be, I don't know, perhaps
more in the world of computer simulation? I'm not sure.
But, I'm also not sure that it can be expressed in pure equations
(but then again, I'm no physicist either).

Thanks Jim.

Hi Jim,

I think I have a related question. Let us assume that the
purest adjudication algorithm has not yet been implemented.
Can you adjudicate Scenario 1 in this thread the way the
purest adjudication algorithm would? Or would this not be
possible without first constructing the purest adjudication
algorithm?

This in turn brings up another, perhaps more philosophically
related question. Assuming that you cannot adjudicate
Scenario 1 until the purest adjudication algorithm has been
built,
[and there is no need to answer this question if this
assumption is not true]
does this means that there are instantiations of this
purest of algorithms that are less perfect than others? And,
as these instantiations become more and more perfect in their
implementation, that they approach one pure adjudication
result.

Finally, assuming that you cannot adjudicate Scenario 1 until
the purest adjudication algorithm has been built, [and, again,
there is no need to answer this question if the assumption is
fasle]
how would
you guess the adjudication would go?

Thanks

you are misrepresenting what I (not speaking for anyone else)

the PUREST adjudication algorithm would have 34 simultaneous
algorithms for determining how each unit moves, given its
order and all the other orders, solved as a simultaneous
equation.

e.g. you have 2x + 5 = y and 2y + x = 20, two equations and
we can solve simultaneously..... let me skip a few lines for
those who want to figure it out for themselves....












y = 9, x = 2. Now you might find a shortcut solution method
that gives you this answer, and as long as it gives you the
answer, let's say you convert them to y = mx + b form,
y = -1/2x +10 and y = 2x + 5 and you graph them and note
where they intersect. Or you might solve them directly
as simultaneous equations, but you might have a criterion
that ease of solution counts for something. Thus, the
inner workings don't matter. You actually are not (I
don't think) solving a system of 34 simultaneous equations
in 34 unknowns anyway. The only question is whcih shortcuts
you take.

Some may be far out, others might not. That's my point.

No one solves a truly pure simultaneous algorithm.

Hi Randy,

Thanks for your thoughtful reply. I apologize if I gave the impression
of dismissing your arguments.

At one point in your message, you suggest that either the main
Scenario 1 or one of the "what if" scenarios is a direct violation
of the rule book. I would like to focus on any direct and obvious
violations on the rule book, as not only are these easier to
understand, but if my adjudicated result is in direct violation of
a clear and obvious rule, then that is something I need to
know about unambiguously and be totally aware of.

I will get out the Diplomacy board (though not necessarily
right at this very instance), all the rule books (as I have copies
of almost every rule book), and review your posting with
an eye for finding any clear and obvious violations of the
rule book that my adjudication resulted in.

If I am "blind" and unable to find any, or lack the experience
to interpret your statements correctly, then I will request your
help in isolating them.

Thanks very much.

Hi Randy and Everyone,

As far as I am aware, no one person has stated
explicitly and directly that they consider my
adjudication of Scenario 1 to be one valid
adjudication of many, given that it is assumed
that everyone may interpret the rules in different,
though valid ways.

To say this another way, if it be assumed that
there exists any one that believes the rules
could potentially be interpreted in different,
valid ways, no one has specifically and clearly
said, to my knowledge, that my adjudication of
Scenario 1 is one such valid adjudication
result.

So, let's assume that my adjudication of
Scenario 1 is simply wrong because it clearly
and directly violates a rule, and that this rule
can be found and spoken of. [This paragraph
is not meant to be flippant; it appears to
be a valid assumption until some person,
other than me,
explicitly says that my interpretation is at
least potentially valid given the rules or
given how the rules might be interpreted.]

I am using the year 2000, fourth edition
rule book, as it is freely available on the
internet and because it has diagram's showing
maps and units, and arrows showing how they
moved, and so forth, so I can read it and
reason about a diagram without setting up
a scenario on the Diplomacy map on my
desk.

Let's consider now Scenario 2:
Scenario 2:
Italy:
Army in Trieste to Venezia (supported in its move by two other units
not shown).
Austria:
Army in Venezia to Trieste (supported in its move by two other units
not shown).
France:
Army in Piemonte to Venezia (supported in its move by one other unit
not shown).

Because Scenario 2 does not involve the cutting of supports,
we need not detail every unit, nor make the scenario
symmetrical.

The issue is not difficult to understand. The
statement of the majority view is, for this
given scenario, that the Italian army's action
of attacking Venezia bounces the French
attack on Venezia, with the result that the
Austrian army in Venezia is not dislodged.

Let us further assume that this is not just
a majority view, but that it is the only correct
way to adjudicate the position using the
rule book.

So, we now need to find what rules in the
rule book bear upon this situation.

The rule book, I might add, does not seem
to have a lot of the "weird" positions, such as
Scenario 2, in it. This is very unfortunate,
because these weirder positions are often
revealing about how many of the rules work
together.

The closest diagram in the rule book that I
can find is Diagram 25 on page 14 of the
year 2000, fourth edition rule book. Note
carefully some of the descriptive text:
"In most cases, this supported attack from
Silesia into Munich would beat the unsupported
attack from Ruhr."

Note also that it does not state the following:
In most cases, this supported attack from
Silesia into Munich would beat the unsupported
attack from Ruhr AND THE UNSUPPORTED
ATTACK FROM TYROLIA.

[The ALL CAPS letters are the words I added to
the sentence]

Can one now extrapolate from this example and
say the following: The attack from Tyrolia into
Munich was canceled because it was met by
an equally apposing attack from Munich into
Tyrolia? For if the attack from Tyrolia to
Munich had any merit worth mentioning, why
wasn't it mentioned in the descriptive text?

I'm not saying what we should or should not do.
I'm just pointing this out because I noticed it
while I was reading through the manual.

In Scenario 2 above, it will be noted that for the
most part, we are not dealing with unit dislodgement.

So, I will now read through the year 2000, fourth
edition rule book beginning on page 6, and note
what I can find that might have some bearing on
Scenario 2 above.

Note that in Scenario 2, we have unequal forces
pressing into Venezia from both sides: the
Italians with a strength of 3, and the French
with a strength of 2. Note that the discussion
of standoffs on page 6 would appear not to
be relevant with respect to the Italians and
the French in our scenario.

Diagram 6, on page 6, is a diagram which is
similar to the dynamic between Austria
leaving Venezia and Italy leaving Trieste:
that is, two units in neighboring provinces
attacking into each other. The rule clearly
says that neither unit moves. And, we can
safely extrapolate, that if the units attacking
into each other were equally supported, again
neither would move.

So far in our adjudication of Scenario 2, we
can very safely say that the Austrians will
not move from Venezia to Trieste, nor will
the Italians move from Trieste to Venezia.
Both sides agree on this point.

Now we come to page 14 and it deals only
with the topic "Dislodgment in Standoff,"
and includes three digrams: 12, 13, and 14.

As this page is often quoted, even though
our Scenario 2 doesn't involve dislodgement
using the majority viewpoint, let's read it
over carefully and see if we can find anything
that bears upon our Scenario 2.

Before reading page 14, let's first decide
which military unit even has a chance of
being dislodged. Certainly the Italians
in Trieste have no chance of being
dislodged from Trieste. Certainly the
French in Piemonte have no chance
of being dislodged from Piemonte.
The majority view says that the Austrians
in Venezia will not be dislodged. The
minority view says that the Austrians in
Venezia will be dislodged. So, the only
real question about dislodgement bears
on the Austrians being or not being
dislodged from Venezia.

As far as I can tell, none of the diagrams
on page 9, Diagrams 12, 13, and 14,
address our Scenario 2 directly and
unambiguously.

So, we will now go over page 9 carefully.
Of course, I may not, being a beginner,
go over it carefully enough, so further
comment will be welcome.

I don't see how Diagram 12 relates to
our discussion.

Concerning the last paragraph in the
left column of page 9, it discusses the
dislodgement of the Turkish army
in Bulgaria. This does not directly
and unambiguously relate to our
Scenario 2 above, because in Scenario 2,
the Italian forces in Trieste were not
dislodged.

Diagram 13 does not directly and
unambiguously relate to our
Scenario 2 above, because the
attacking forces coming from
Sevastopol and Bulgaria are of equal
strength of 1, and because the
unit "in the center province", that
being Rumania, did not even stay
there, but instead dislodged the
unit directly to its south.

So, there are many aspects of Diagram
13 which do not have any relationship
at all with what actual is happening in
our Scenario 2.

Diagram 14 simply is a repeat of Diagram 13,
but in Diagram 14, they add supporting
units.

Tthe last paragraph in the right-hand column
of page 9, it says: "There was no standoff".
But this is under the scenario where the
Russian army was NOT ordered to
attack Rumania from Sevastopol. So, this
is clearly not relevant to our discussion,
for if two armies are not ordered to attack
the same province, obviously there is
no stand-off.

In the last paragraph in the left column
on page 9, it says, "That Turkish Army,
and the Russian Army in Sevastopol are both
ordered to Rumania, which would normally
cause a standoff."

This quote is flawed in that it does not give
a complete description of the new scenario
being discussed. In this new scenario, is
the Russian army in Rumania holding?
In this new scenario, is the Russian army in
Rumania attacking Bulgaria with no support
or with support of 1, 2, or 3? None of these
details which would bear upon our Scenario 2
are mentioned. So, "normally cause a standoff"
can be seen as a very generic type of statement.
Yes, normally, if you don't talk about any other
units, such as in Diagram 4 on page 6, a
stand-off occurs. The text does not address
any specific scenario in detail, but is simply making
a broad, general statement.

And, the same quoted text above continues,
"However, because Rumania dislodged the
Army in Bulgaria, it has no effect on Rumania
at all."

We can re-write this, if we want: "However,
because the Russians attacking from Rumania
dislodged the Turkish Army in Bulgaria, the
Turkish army in Bulgaria was not involved in
a stand-off with the Russian army invading
into Rumania from Sevastopol." And, we could
continue, just for clarity: "Unlike Diagram 12
where the German army attacking
from Munich to Silesia WAS involved in a
stand-off even though it was dislodged, that is
not the case in Diagrams 13 and 14, because
in these later diagrams, the attacking and
dislodged military unit was dislodged by
the very unit it was attacking."

Note, by the way, that that added clarity is
all that this quoted phrase means: that is,
this phrase: "which would normally cause
a stand-off" is referring to a totally different
case as found in Diagram 12 or Diagram 4
on page 6.

After all, the point of the discussion is
"Dislodgment in Standoffs." To take the
phrase, "it has no effect on Rumania at all"
and blow it out to mean far more than it
meant to mean is not justified in the text.

In fact, the "at all" tacked on to the phrase,
"it has no effect on Rumania at all" is nothing
more than simple emphasis; it is an attempt
to emphasize the differences between the
scenarios presented in Diagram 12 verse the
scenarios presented in Diagrams 13 and 14.

My reading of the document now suggests to
me more clearly, now that Randy has encouraged
me to investigate, and I appreciate it, that this
is one, badly written rule book! Could they not
have one "advanced" example to tie together
a few threads? What a mess!

I'd say, and everybody can have their own opinion,
that the year 2000, fourth edition rule book does
not clearly and unambiguously preclude my
interpretation: namely, that in scenario 2 given
above, the French dislodge the Austrians from
Venezia.

Now, did I actually think about this before I came
up with my minority opinion? No. But, now that
Randy has invited me to study this issue, I have
to admit that I am quite surprised that there is,
in my opinion, still breathing room for the
minority view.

Please remember that the above are my interpretations
and opinions. And, Randy, I do appreciate your good,
sound writing, which has forced me to re-examine
the rule book, and, I have enjoyed doing so.

I welcome hearing responses to my analysis.
Thanks all, and thanks Randy
