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: http://www.chess-dictionary-chesmayne.net/Shatranj.htm.
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.'
May be you find something interesting on http://en.wikipedia.org/wiki/Timeline_of_chess or http://history.chess.free.fr/variety.htm
I get an error message when trying to load Zillions file for Timur Chess (with latest version of Zillions on WinXP): 'bitmap can be loaded: images\Alfaerie\timurboard.bmp'. I checked that the image is there. Is the bitmap corrupted?
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 :-) ?
Thomas, I like Shogi preset with white marble board as well.
Can we expect that Kasparov comes up with a new chess variant, like Fisher did?
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.
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)!.
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 plays software sold on http://www.chaturanga.com ? From screenshot is 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
