Yes, now I noticed that color settings are stored per specific game type. I
think, it would be nice to have possibility to apply the color changes to
all game types (may be with an option to apply only to one game type as
now). By the way are there any reason to restrict the number of available
colors to 48? With more available colors it is easier to find a nicer
color scheme.

I also found a bug in Bird's Chess. ChessV castled out-of-check in
position after:

d2d4 f7f6 i1h3 g7g5 g2g3 g5g4 h3i1 h8g7 f2f3 i8h6 f3g4 h6g4 h1f3 e8g6 i1h3
d7d6 e2e4 c8d7 e1e2 e7e5 d4d5 f6f5 b1c3 h7h6 h3f2 g8j5 f3g2 j5i6 f2g4 i6g4
g2f3 g4f6 c1d2 g6f7 d1f2 j8g8 f1c1 f5e4 f3e4 j7j5 h2h3 b8a6 g1j4 a6c5 e4g2
i7i5 j4i3 f6i3 f2f7 d8f7 j2i3 g7f6 j1j5 g8g3 d1f1 c7c6 j5j8

ChessV played 0-0-0 here, despite King being in check by rook on j8.

On Wikipedia http://en.wikipedia.org/wiki/Buddhi_Chal you read:

Buddhi Chal is a Himalayan variant of chess. The name means mind game in
Nepali, and is from the same root word as Buddha (the Pali word budh,
meaning, 'to know').

Does anybody heard about this chess variant?

Would be nice to have possibilty to move by clicking with mouse on starting postion in diagramm and then on the destination position. This is how most of other game sites work.

Interesting and rich content, however there are something which can be
improved:
* images are missing in many articles (for example in
http://www.chess-dictionary-chesmayne.net/Chaturanga.htm)
* background sometimes make the text difficult to read (for example
background in red color)
* some articles use too much links, for example:

Would be nice to have Alfaerie Graphics for this preset. This is my favorite graphics and I always select it when playing other chess variants here.

Please look at http://en.wikipedia.org/wiki/Judit_Polgar
'...In 2004 Judit took some time off from chess to give birth. She was
consequently considered inactive and not listed on the January 2005 FIDE
rating list, meaning that her sister Zsuzsa temporarily became the world
number one woman player. Judit is expected to return to chess at the Corus
chess tournament in January 2005.'

Will we play in tournament a balanced version of Marseillais Chess or regular one? I would prefer balanced version.

Which piece is stronger, General or Elephant? Is it worth to exchange General or Elephant for two pawns? Are there any writings from 1000 years ago about piece values in Shatranj :-) ?

Can we expect that Kasparov comes up with a new chess variant, like Fisher
did?

Andreas Kaufmann wrote on Fri, Mar 11, 2005 08:34 AM UTC:
I just recalled that Kasparov actually already invented a kind of new chess
variant: 'Advanced Chess' (see e.g.
http://en.wikipedia.org/wiki/Advanced_Chess).

Is it possible to switch ChessVariants pages to some kind of <a href=http://en.wikipedia.org/wiki/Wiki>Wiki</a> system, like used by Wikipedia? Then there would be no shortage in authors, editing articles in Wiki system is very easy, every reader is a potential author!

Another variation would be that the player, who reaches initial position
first, wins. The game can start e.g. with white King on a1 and black one
on h8 (or other postions to deversify the game). Then black starts with
undoing the last move. As 'uncapturing' of pieces is disadvantageous and
would never made otherwise, then it should be obligatory to 'uncapture',
if possible. So the game could start (black moves are shown before white
also in notation):

-1. kg8 (*Qh8) // black uncaptures white queen, undoing the last move
kg8xh8.
-1. ... Qf6 (*nh8) // white undoes Qf6xh8
-2. nf7 (*Rh8) Rh1 (*bh8)
-3. bg7 (*Rh8) Rh2 (*rh8)
. . . etc.

I need to think something more about uncapturing of pawns, but may be no
restriction should be made here, so that if e.g. white leaved with doubled
pawn and all black pieces already on the board, then white can't win
anymore. If black in the same situation, then it is a draw. 

There should be probably a rule for uncapture of bishops to forbid that
two bishops e.g. on light squares are produced.

Andreas Kaufmann wrote on Fri, May 27, 2005 09:32 PM UTC:
No restriction on pawn uncaptures (except that it can't be done on first
or last rank) could probably lead to a too drawish game. A player just
needs to delay pawn uncaptures until all other pieces are uncaptured and
than try to uncapture all opponent's pawns on the same file. 

So, I would suggest the following rules:
* Pawn uncapture is not allowed on the file where there is already pawn of
the same color. For example, black can't uncapture white pawn on g-file if
the file already contains another white pawn.
* Uncapture is also not allowed if it produces a pawn, which is behind
player's pawn. For example, black can't uncapture white pawn on g7 if
there is already black pawn on g2. 
* A player can't uncapture more pieces then present in usual chess setup
(light and dark-colored bishops are considered as different pieces).
However if a player unpromotes one of his pieces, that piece becomes
available for uncapture again. 

The game finished when:
* A player reaches starting postion with his pieces (this player wins).  
* A player can't make a legal unmove (this player loses).

There is already a ZRF file for this game without any restriction on
uncaptures: 'Unplay Chess' by  Karl Scherer (can be downloaded from
Zillions of Games pages:
 
http://www.zillions-of-games.com/cgi-bin/zilligames/submissions.cgi/26414?do=show;id=966

I slightly modified it to place white king on a1 and black on h8 in
initial position. Here is my first game against Zillions (I played
black):

-1. kg8 (*Rh8) // black uncaptures white rook: kg8xh8
-1. . . . Pg7 (*rh8) ?? // white unpromotes the rook and uncaptures the
black rook, undoing the move P g7xh8 R. This move loses the game.
-2. rh7 (*Qh8)! // undoing rh7xh8. Black wins as white doesn't have any
unmoves which wouldn't leave black king in check by queen on h8.

Another short game against Zillions:
-1. kg7 (*Qh8) Qh4 (*rh8) ??
-2. rh7 (*Bh8)!

White loses, as it can't remove check by bishop h8 to king on g7. I first
thought that -1. kg7 (*Qh8) quarantees win for black, but then found the
only defense: -1...Qh4(*bh8)!.

Andreas Kaufmann wrote on Fri, May 27, 2005 10:05 PM UTC:
One more game. I played it against myself, trying to find a forced win for
black. As surprise, white won!

1. kg7 (*Bh8) Ph7 // white unpromotes bishop, there were no uncaptures
possible, so a regular unmove is allowed
2. kh8 (*Pg7)?? Pf6 (*pg7)!

White wins as black doesn't have any legal unmove now.

See Wikipedia's article on <a href=http://en.wikipedia.org/wiki/Time_control>Time control</a>: <br><br> <i>In tournament chess the most common time controls for professionals are at 40/2, SD/1 time controls, which means that the first 40 moves must be made in two hours and then all remaining moves be made in an hour. Any extra time from the original two hours carries over to the sudden death time.</i>

After this match with Adams is especially amazing failure of Hydra in <a href=http://www.chessbase.com/newsdetail.asp?newsid=2461>Freestyle Chess Tournament</a>, where human players were allowed to consult computers. Hydra didn't even made it into quarter-finals and the winners were two amateur players, not even masters, who used three average desktop computers!

Are there a ZRF on this game? Does anybody already tried out how strong

looks quite professionally made.

Greg, this was not me who added a link to BrainKing.com. You can check this
by yourself, see history of the page:
http://en.wikipedia.org/w/index.php?title=ChessV&action=history

In case of 'edit war' you should describe the situation on the
discussion page of the article and ask other editors for mediation. By the
way I just removed the link to BrainKing.com.

Thanks for creating a preset for this interesting game! One small remark: the preset can't yet detect a checkmate, see <a href=http://play.chessvariants.org/pbm/play.php?game=Balanced+Marseillais+Chess&log=rlavieri2003-andreas-2005-207-126> this game</a>.
