I'll add <b>Ruddigore Chess</b> to my 'to do' list, but since that's already 1.83 miles long, don't expect it this quarter. But I will almost certainly write a Zillions Rules File for it, and bully poor Tony Quintanilla into playing it with me by e-mail so I can see if it works or not before publishing. Someday. <p> (I realize I don't <em>need</em> Zillions to play the game by e-mail, but it makes it more convenient and enforces rules that might get missed. Also, I find programming a game a good way to examine a game's rules in details.)

John Lawson wrote on Wed, Apr 3, 2002 06:54 AM UTC:
So, given the amount of chatter about Chatter Chess and Ruddigore Chess and
so on, do we need 'virtual' comment pages so we can discuss variants that
haven't actually been posted?  Then, going forward, the comments will be
where they belong.  I mean, who's going to think about looking for comments
about Ruddigore Chess attached to the Archoniclastic Chess page?

Also, to David, I like the little subtle link to the recent comments at the
top of the What's New page, but I don't think in GMT.  Maybe we could
include the current time in GMT, or the time elapsed since the last
comment, or something like that.

John Lawson wrote on Wed, Apr 3, 2002 07:26 AM UTC:
Peter, I've recently been playing Grand Camelot in another venue.  Grand
Camelot is a four-player version of Parker Brothers Camelot game.  (To the
peanut gallery: Yes, I know it's not a chess variant; let me finish.)  

Grand Camelot has two unusual features for a four-player game:
1 - Partners sit side by side.  Translating to this game, Red and Green
would be partners against Yellow and Black.
2 - The turn sequence is a 'figure-8'.  Translated to Chaturanga 4-84, that
would be Red - Yellow - Green - Black (repeat)

This small change works surprisingly well, and I've wondered if it would be
as successful in a 4-player CV like this.  I generally find 4-player
abstract strategy board games annoying, but Grand Camelot is lots of fun
and very exciting.

Also, the comment about the ZRF being double-dummy brought an idea to mind.
 Has there been a CV (e.g. Bridge Chess or Whist Chess) where the players
bid to achieve a certain outcome?  The partner of the 'declarer' sits out,
and the defenders play without communication.  This might be a possible
thing to design.  One could even play a Feeback version with ones
physician, attorney, and accountant.

<P>A CV in which the players have goals is my Hi-Lo Chess, in which each player secretly selects one of the goals W, L, D, WL, WD, LD, or WLD.<P>In order to get more variety in the selection, we used to write a pack of paper slips with goals and require the players to shuffle and use the top goal from the pack.<P> There must be a 'mate me' rule and a 'perp me' rule -- if at the end of your move your opponent has a mate in 1 or a perpetual check, you can require that it be played.<P> Scoring: if you have one goal and achieve that goal you get 1 point for the game; if you have 2 goals you get 1/2 point if you succeed.

Well, the game has been played a fair number of times against the computer and at least once by e-mail vs a human opponent, and it seemed to play fairly well (of course, there might be something wrong with it, after all I <em>lost</em> :)). <hr> A play order of AABB instead of the more usual ABAB for a four-player partnership game transforms it into a limited double-move variant, rather like one whose name I can't recall, where you get to move a piece on the left side of the board and one on the right side each turn. Limited double-move variants tend to be fun and exciting, so I can see the appeal, and spliting the double-move between partners has some piquant aspects, particularly if communications are restricted and reading minds is not at least one of the partner's strengths. I think I may add an AABB variant as to the Chaturanga 4-84's ZRF (still double-dummy, alas). <p> As for bid multiplayer Chess with a dummy . . . Could be done. Should it? :) <hr> Thanks for the kind words, Tony.

While I agree that discussions of new game ideas are valuable, I don't think they are appropriate for the feedback and rating system. It's better to keep the discussions relating to a particular page on our internal feedback system, and use our discussion group when the commentary digresses to new game ideas. The discussion group has many more features than my crude feedback system, so I think it's better to use that. That is, unless you want me to build a discussion group system that lives on the chess variant pages... :)

John Lawson wrote on Fri, Apr 5, 2002 02:09 AM UTC:
I fall between Peter and David here.  When I write a comment, I don't
really plan it.  Something in the page, or another comment sets me off, and
I just start writing.  If it leads somewhere not completely germaine to the
page being commented on, so be it.

BUT, the result is that discussions that are potentially interesting or
inspiring get buried attached to pages that effectively conceal them from
later browsers.  (Look at the recent discussion attached to the
'Archoniclastic Chess' page.)

To do the thing properly, comments should be limited to the variant they
are attached to, and any flight of fancy should be moved to the discussion
group.  I think this is against human nature (at least mine) and I would
probably never make 50% of those posts.  Furthermore, the discussion group
posting may be cryptic outside of context of the variant page that inspired
it.

On the other side, the number of people 'misusing' the comment system are
relatively small.  It would be a huge waste of time and resources to build
a parallel discussion system for a handful of 'chatterers'.  Also, the
public discussion board has a better possibility of attracting random
searchers.

Maybe a compromise is possible.  Let me note here that I am no programmer,
and I have no idea how difficult any particular idea would be to implement.
 An idea that seems simple to me might be to allow the writer of an
extended comment to select a small set of keywords ('Ruddigore',
'double-move') which the comment system could also search for.

Better ideas?

The comment system allows you to see the whole discussion on one page,
instead of needing to access (and then page down past all the garbage) a
new page for each message.

This is a huge advantage, and I expect that people will abandon the yahoo
thingy and flock to the chessvariants.com comment pages.

📝David Howe wrote on Fri, Apr 5, 2002 04:13 PM UTC:
Ok, I'll look into extending the feedback system to allow some sort of message threading based on something other than existing pages. I understand why people do not like the yahoo group system, although it does have some nice features. Give me a few days to come up with something.

Chatter Chess. Variant based on the idea of line chatter where rider pieces can switch to other friendly pieces' lines of movement. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Peter Aronson wrote on Fri, Apr 5, 2002 05:40 PM UTC:Excellent ★★★★★
You know, I can't see any reason (aside from restraint) why stepping pieces couldn't take advantage of chatter even if they can't create it (sort of like a low-power line mixed in with higher-power lines). Then, if a stepper could move to a square containing a rider's line, it could ride away on it! In that case, castling and Pawn-double-step could definitely generate chatter lines (and we'd have to distinguish between capturing and non-capturing chatter lines). Of course, chasing down a King supported by a Bishop could be rather difficult . . . <p> The above would probably result in a fairly crazy game, but it would also come closer to working with different armies. <p> And for the list of possibly unplayable games, I'd like to add <u><a href='../d.betza/chessvar/confu01.html'>Confusion 1b</a> Chatter Chess</u>.

gnohmon wrote on Sat, Apr 6, 2002 02:21 AM UTC:
That was an excellent chatter response.

Responsible usage of the rules tells us that a piece which takes only one
step ends its move after that one step and therefore is not eligible to
chatter. However, your idea sounds like a lot of fun!

One can always arbitrarily restrict Kings and Pawns from participating in
the fun; and I think this would be necessary, not only because it appears
to be too difficult to chase down a King supported by multiple riders (note
that 'a K supported by a Bishop' can only run towards the Bishop), but also
because the offensive uses of Chattering Pawns would dominate the game, as
they do in N-Relay II.

Decimal Chatter Chess, on a 10x10 board, would become quite interesting if
you had the Pawns on the third rank, all Riders on the first, and a second
rank full of weak steppers -- the usual suspects, W, F, Crab, Barc, A, and
D -- because the early play would be dominated by the weak pieces being
thrown forwards by the power of the riders. You'd need to arrange your
pieces very carefully, making room for the weak pieces to get past the
Pawns, setting up intersecting lines for the riders, and putting the
weakies where they could join in the fray but not get in the way. All the
while trying to maintain a defense against the pesky foe.

People should know that the excellent diagram that makes it so easy to
visualize the chatter moves was added by the editor, not the author.

I would like to announce that I am going to be running an Omegachess
tournament by email on Richard's Play By Email server at
http://www.gamerz.net/pbmserv
In order to play in the tournament you must have a PBM userid.
Check out http://www.gamerz.net/tutorial.html and
http://www.gamerz.net/commands.html 
if you are new and want to sign up for a free userid and password
on the server. You do not have to have ever played Omegachess before
on the server to compete in this tournament. If you would like to play
in the event please email me your PBM userid to DavidNYJfan@hotmail.com
I have not yet decided exactly how I am going to structure the Omega
tournament. It will probably be a round robin tournament, with between
4 to 8 games in the first round, and a certain number of players 
advancing to a second and final round.

I would also like to announce that I am also going to run a chess
tournament on PBM too. This is traditional orthodox chess!
This tournament is open to the first 25 players who email me to enter.
I will be creating five 5-man sections. Each player will play a total
of 4 games, 2 as white and 2 as black, one game against each of the
other players in the tournament. The 5 section winners will then
advance to a final 5-man section for the championship of the tournament.
In the event of a tie for first place in a section the first tiebreaker
is head-to-head result. In the event of a draw or a 3-way tie where
A beat B, B beat C and C beat A, all tied players advance to the finals
and a larger final section will be created. Again, to compete in this
tournament you must have a PBM userid. You may enter both tournaments
if you like. When emailing me please make sure to specify which
tournament you are entering. Thanks again and good luck!!

Just as a note from the author: Ed's variant of doing queen attacks does
work well, also. But don't get too trigger-happy- it's good defense. Make
sure you don't get blindsided by a bishop in the classic variant!

The major downside to the queen shot variant is that then you can't
reasonably use a bishop to move in for the kill; you pretty much have to
lose two pieces to the shotgun, unless you use knights well...

I'd like to see this article expanded to include other types of ...er..
cursed pieces and cursed players.

For example, how about Restless (or Hyperactive or Flying Dutchman)
pieces that have to be moved each turn (e.g., the King in Triplets)?

Or how about the Ruddigore Chess curse that requires a player to
capture an enemy or discard a friend at each turn?  (By the way, a similar
curse is imposed on the players of Sudden Death Chess.)

Perhaps you could also include Hesistant (or Hamlet?) pieces that
require two or more turns to move (somewhat like Ralph Betza's
Inchworms).

Finally, how about Cuckoo pieces that can only capture friendly 
pieces? (Some species of cuckoo place their eggs in nests of birds of 
other species.)

More than excellent, superb!

Harry Bird is one of history's greatest non-GM chessplayers. His
originality combined with his longevity (he played against Morphy, and he
played against Lasker, maybe even against Vidmar, if I remember rightly)
combined with his strength (not a world champion, but surely stronger than
me) make him one of the more interesting personalities in modern chess
history.

I have often heard of this book, but was never fortunate enough to find a
copy. Now I can read it at last.

More than superb, optimal!

Bird lost a match to Steinitz by a mrer 7 to 6. 

'Bird is one of history's greatest non-GM chessplayers.' I said, but I was
wrong.

Steinitz was a tough cookie. Losing 7-6 makes Bird a GM in my estimation.

The book itself is very disorganized and tough to read, with many passages
that are repetitive and uninteresting.

However, enough of Bird's personality shines through that I am glad to have
made his acquaintance.

To correct what I said earlier about the time of his career -- it was from
before the first tournament up to the times of Lasker.

Chatter Chess. Variant based on the idea of line chatter where rider pieces can switch to other friendly pieces' lines of movement. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Peter Aronson wrote on Sun, Apr 7, 2002 11:18 PM UTC:
I think I was a little unclear about my idea. A stepping piece would move on a chatter line if one of the squares that it could move to was on that chatter line. Thus, a player with a King on <b>a3</b>, and a Bishop on <b>a1</b>, with the Bishop having a clear move to <b>h8</b> could move the King all the way to <b>h8</b>. Which is why it could be hard to run down the King without disposing of the Bishop first. <p> But in any case, your suggestion to exclude the King and Pawns from this behavior is probably wise, leaving it for various Faerie and CDA pieces in their stepping moves.

This appears to be an excellent game, with a lot of thought and effort.

Is it a chess variant? Not really, even though it uses chess pieces. It's a
mathematical (topology) abstract game, and you might find many fans for it
in rec.games.abstract -- give it a try!

Many abstract mathematical games become popular and widely played, but the
market for them is not 'chess variant' people. 

I haven't tried Chain of Fools, but if it's as good as it looks you'd be
doing yourself a big favor by taking the game over to rec.games.abstract,
where you can find folks who will really appreciate it.

Overprotection Chess. If an attacked piece is more often defended than it is attacked, it gains extra powers. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Peter Aronson wrote on Mon, Apr 8, 2002 07:37 PM UTC:Excellent ★★★★★
This looks like fun! I particularly like that once you overprotect a Pawn by two (easy enough -- just take an unattacked Pawn and give it two supporters), suddenly it captures forward and to the side. <p> I find myself wondering if overprotection is calculated recursively. That is, when determining overprotection, is overprotection taken into account? <p> Consider the following: <blockquote> White Pawns at <b>a3</b>, <b>b4</b> and <b>c3</b>; <p> Black Pawns at <b>a6</b>, <b>b5</b> and <b>c6</b>. </blockquote> Assume white's move. Can the white Pawn on <b>b4</b> capture the black Pawn on <b>b5</b>? If you apply white's Wazir capture first, then it can (since it is overprotected by two, black not having a Wazir capture as it is only overprotected by one), if you apply black's Wazir capture first, it can not (since then the white Pawn will only be overprotected by one). Curious, no?

A Pawn or piece must be attacked in order to be overprotected. I said that,
right?

'and dynamic' ... 'where checkmating the opponent could also checkmate
you!' means that the enemy K is defended several times (but of course not
attacked) so that when you attack the enemy K it becomes overprotected and
gives check to your nearby King. I could have made that clearer, right? But
you're correct, even the closest reading of this doesn't really say whether
it's recursive. Yes, why not recursive, gosh darn it and gosh darn it
again?

If you could overprotect an unattacked piece, this would 'merely' be a new
(and perhaps an excellent) form of Relay Chess.

So, should add a line that the powers gained by an overprotected piece can
be used to overprotect another piece.

Should add a line 'therefore you can destroy your opponent's overprotection
by moving your attacker away'.

And should add the explanation of how giving check[mate] can check[mate]
yourself.

Better now?

But there's still a lovely paradox here. <p> Consider: <blockquote> White has Pawns on <b>a3</b>, <b>b4</b> and <b>c3</b>, and a Rook on <b>b1</b>. <p> Black has Pawns on <b>a6</b>, <b>b5</b> and <b>c6</b>, a Rook on <b>b8</b>, and a Bishop on <b>d6</b>. </blockquote> The white Pawn on <b>b4</b> is attacked by one piece, and defended by three, so it can move and capture as a Wazir. Which means it attacks the black Pawn on <b>b5</b>. The black Pawn is then attacked by one, and defended by three, so <em>it</em> can now move and capture like a Wazir. But this reduces the white Pawn on <b>b4</b> from being overprotected by two to being overprotected by one, which means it can no longer capture the black Pawn at <b>b5</b>. But if it can not capture the black Pawn at <b>b5</b>, the black Pawn isn't attacked, and so can't capture the white Pawn which suddenly overprotected by two, which means it <em>can</em> capture the black Pawn. But it can't . . .

I've heard vague rumours that this game, or a game very much like it, is
still played at Miskatonic University...

The excellent rating applies to presentation and originality. I have not
playtested this game (yet). Truth be told, I'm not sure I *want* to! :)

This is something new in a way, or at least something not often done. It is a game where the two sides, while having the same movement, have different board topologies to deal with in the opening and midgame, and I think it an interesting idea. Now, if there was just some way to determine if it was balanced . . .

Apart from the paradox problem, the need to take into account temporary
powers makes assessment of overprotection a bit complicated. 

I would suggest ignoring temporary powers in assessing overprotection.

Wow!!  

Who said theme doesn't count in abstract games?  I want to play this, but I
think I'm going to be disapointed when the pieces remain silent.  I want to
see a ZRF, but not too soon.  Whoever does it needs to do a good job on the
graphics, not to mention audio, to do the game justice.

You have trapped me and won the game of game-making!

You suggested recursive, and I said 'sure, okay', and then you hoisteded me
with me own petard by pointing out a most ingenious paradox, more ingenious
than Doctors Einstein and Schweitzer. I am bereft, like an apprentice to
Pilate.

Where can I find an mp3 of busy editorial beavers whistling the 'Happy
Editor' song as they undo a previous change?

Shall we go with Tony Paletta's suggestion, and avoid all temporary powers when calculating overprotection? It does make it simpler, and importantly improves clarity.

'Favors Black, you think? Then perhaps you will be willing to offer me
substantial odds as we play a game for some enormous stake of money, 
perhaps a penny on a1 doubled on each successive square?'

I had almost put the above statement into the story of getting a regular
chessplayer to play Chigorin Chess, somewhere after the part where 'variant
rhymes with deviant and that starts with d and rhymes with t and stands for
trouble.', and way after the part where the regular chessplayer says with a
sneer is that some kind of fairy chess.... (I'm not suggesting that
you're
the offensive non-PC 'regular chessplayer'; the misinformation
about relative values of N and B is part of general unwisdom, that's
all.)

Read any monograph on the Chigorin Defense. You'll find that many 
players now believe the N to be superior in the early stages of the game,
which agrees with my findings on the theory of chess values so I think
it must be right.

Given the advantage of the first move to go with the advantage of fast
development, the *white* side in Chigorin Chess probably has a large
advantage. In order to Castle K-side, Black needs to move two Pawns and two
Bishops; and one of those P moves looks suspiciously like a weakening
move.
White can go 5.O-O at the earliest, but Black can choose to go 3...O-O;
think about it!

And, of course, this is the whole point of Chigorin Chess! You can get a
'regular chessplayer' to play, because he will want to prove that the
Bishops are so much superior...

Yes, I'm afraid that recursion (drat and drat again) must be explicitly forbidden, which is too bad because it sounded like fun.

It recently occurred to me that I might have named the Zombie an Iron

But perhaps that would have been inappropriate after all. Lovecraft never
played a game of Nethack in his life.

Very interesting.

1. At first sight, the board seems unbalanced because a Black R at b6
attacks
both b2 and c2, but a WR b3 does not get its power doubled.

I would suggest that in the long run this advantage is much greater than
W's advantage of first move.

2. The Bf1 can't go to c4, right? Perhaps Bishops should be replaced by
something else. (Not zFF, that would increase Black's advantage.)

3. A Knightrider on a6 attacks both f2 and e2, right? And a Rose on h6
attacks both d3 and e3, and therefore... interesting.
