| Posted by rich_sposato playcomputerchess.net 6/29/2008 21:32:50 Play computer chess |  Subject: Can you castle onto an occupied square?Message: I looked up the castling rules on Wikipedia and FIDE, and found nothing to prohibit the king from castling onto an occupied square. I assume the king would capture the enemy piece on the target square just as it would capture a piece on any square during normal moves. Wikipedia says: (  en.wikipedia.org)
Castling is permissible only if all of the following conditions hold: 1 The king must never have moved. 2 The chosen rook must never have moved. 3 There must be no pieces between the king and the chosen rook. 4 The king must not currently be in check. 5 The king must not pass through squares that are under attack by enemy pieces. 6 The king must not end up in check (true of any legal move). 7 The king and the chosen rook must be on the same rank. FIDE says: ( www.fide.com)
The right for castling has been lost: 1. if the king has already moved, or 2. with a rook that has already moved Castling is prevented temporarily if: 1. the square on which the king stands, or the square which it must cross, or the square which it is to occupy, is attacked by one or more of the opponent`s pieces. 2. there is any piece between the king and the rook with which castling is to be effected. Has this situation ever occurred in official games? If the king may capture while castling, this would be the only situation in which 3 pieces are touched in a single move. 1. the king 2. the rook 3. an enemy piece | ||||||||||||
| Posted by premium_steve playcomputerchess.net 6/29/2008 21:47:49 Play computer chess | Message: since there is a piece between the king and rook (an enemy piece), i don't think castling would be possible. did this come up in one of your games, rich? it would be a fun move to make, all the same. :) | ||||||||||||
| Posted by rich_sposato playcomputerchess.net 6/29/2008 21:57:41 Play computer chess | Message: Yeah, I see. When I first read that, I was thinking only of the square which the king would cross as between. Now that I think about this again, I see that of course the king will land on a square between the king's and rook's starting positions, so any enemy piece there will prevent that. No, it did not come up in any game I played. Thanks, Rich ——— Title Match Is Tied With One Game to Go in Regulation — There is one more regulation game left in the World Chess Championship match in Sofia, Bulgaria. If neither Viswanathan Anand of India, the titleholder, or Veselin Topalov of Bulgaria, win on Tuesday, they will have to go to overtime. On Sunday, they drew Game 11. It was the seventh draw in the match, though, like some of the other draws, it was not without drama. Anand had White and opened with the English — the first time in the chess match he had done that. No doubt he switched openings to try to catch Topalov off-guard, but it did not work. The players followed well-known theory for 10 moves, and then Topalov deviated from earlier games, though it was a minor ... Posted by chessnovice | playcomputerchess.net 6/30/2008 10:18:33 Play computer chess ...Message: If you check the FIDE link you provided, and you'll see that it says: "Article 3.1: It is not permitted to move a piece to a square occupied by a piece of the same colour. If a piece moves to a square occupied by an opponent`s piece the latter is captured and removed from the chessboard as part of the same move. A piece is said to attack an opponent's piece if the piece could make a capture on that square according to Articles 3.2 to 3.8. A piece is considered to attack a square, even if such a piece is constrained from moving to that square because it would then leave or place the king of its own colour under attack." ——— Anand's missed opportunity — The chess World Championship is on a knife-edge. But Anand could have made a mark in this game. Anand and Topalov go into the 12th game of their chess match today with scores level. If drawn, tie-break rapid games will be played on Thursday. Topalov's declaration before the match that he would neither offer nor accept a draw has clearly had a liberating effect on both players, resulting in one of the most entertaining world chess championship finals we have seen in years. All the games have been long and hard-fought, so it's hardly surprising that tiredness is affecting play. Anand missed several chances to win in game 9, Topalov had a promising endgame in game 10 but ... Posted by cyberknight999 | playcomputerchess.net 6/30/2008 19:15:09 Play computer chess It would be a cool move but...Message: FIDE Article 3.8.2.2.b ——— Playing for the World Title, Minus Any Fireworks — Before a world chess championship match, players spend months looking at their opponent’s games and studying opening systems, often with the aid of chess computers and databases. They also hire trainers, who are called seconds, to help. It is a time- and labor-intensive process. That is one of the reasons that fans look forward to the chess matches. They want to see what the players will do and what new ideas they have discovered, particularly in the openings. The current world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria has been as closely contested as predicted. But there have been no eye-opening innovations. Game ... Posted by kinderboy | playcomputerchess.net 9/01/2008 15:18:46 Play computer chess ITS NOT LEGAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Message: ——— With Another Draw, Chess Championship Match Remains Tied — Game 10 of the world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria, ended in a relatively uneventful draw on Friday. With only two games remaining in the best-of-12 series, the players are tied with 5 points apiece. If the match should remain tied after the last two games — which is a real possibility at the moment — it would go to a tie-breaker of four rapid games (each player starts with 25 minutes and has 10 seconds added to his time after each move). Such a tie-breaker was used in the 2006 world chess championship match between Topalov and Vladimir Kramnik of Russia. After each player won a game, and one ended ... Posted by throneseeker | playcomputerchess.net 10/09/2008 19:35:25 Play computer chess CastlingMessage: The short answer to the question is NO as has been stated in a variety of fashions. ——— Title Match Remains Tied After Champion Misses Win — With the world chess championship match having entered a critical stage, Viswanathan Anand of India, the titleholder, switched openings in Game 9, hoping to recapture momentum and the lead that he relinquished with a loss in Game 8. He almost did. But, with victory in sight, Anand faltered and missed a couple of winning continuations, which allowed Veselin Topalov of Bulgaria, the challenger, to salvage the game and keep the best-of-12 match tied. In each of the previous games he had White, Anand had steered the opening into the Catalan system, which is solid, but not too dynamic. In Game 9, he played 3 Nc3 instead of 3 Nf3 for the first time. That gave Topalov ...

Message: Board! Or at least it used-to-be possible. It may have changed, but I was surprised to actually have personally seen it work in the past. Other than that, as they say, #3 Wiki and #2 FIDE pretty much cover the matter. Tho that would be a fun game alteration for skittles play, to be able to o-o or o-o-o and capture anything the King or Rook land on (or sweep across, on b1 or b8 for eg.!?). Also "Uncastles" can add an interesting twist as a Chess variant. A bit harder to pin that king down ... Does the GK bit still work? Well I don't know offhand. |
