| Posted by rich_sposato play-chess-online.com 6/29/2008 21:32:50 play online 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 rich_sposato play-chess-online.com 6/29/2008 21:57:41 play online 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 |

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." |

| Posted by ccmcacollister play-chess-online.com 10/10/2008 10:07:28 play online chess | ...YES~! 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. |
Chess news: Victory Caps Breakout Year for a Player From Brooklyn -- In most chess games between top players, victory is usually determined by a few minor errors by one of them. Blowouts are rare. That was not the case at the 93rd Marshall Chess Club Championship, which ended last weekend. The chess club, on West 10th Street in Manhattan, is one of the oldest and, based on its membership, strongest in the country. The club is named after Frank J. Marshall, the United States champion from 1909 to 1936. Marshall was a swashbuckling player, and he would have appreciated many of the games at this year’s tournament. The field included eight grandmasters and three international masters. The runaway winner was Alex Lenderman ... Chess notes -- The month of December has produced considerable drama and new champions for chess archives. First, the 128-player World Chess Cup field was, after knockout play, finally reduced to Ruslan Ponomariov of Ukraine and Boris Gelfand of Israel (formerly of Belarus), both of whom had survived six rounds. The subsequent struggle between Gelfand and Ponomariov was a real nail-biter. They drew their first four games at normal time controls. The rapids also produced a tied score. Play then moved on to Blitz, a full game in five minutes for each player. Here, both competitors played queen side openings, but Gelfand excelled, winning the first game by trapping Ponomariov’s queen, resigning ... Great intuitive sacrifice -- The exchange sacrifice -- trading a rook for a knight or a bishop -- is a magnificent tool in today's chess. It seldom wins outright. It is played for positional gain and calculation is often not required. Former world chess champion Tigran Petrosian loved it because he used it to get squares from which he could suffocate his opponent. The sacrifice is best suited for the black pieces in the Sicilian defense where the semi-open c-file tempts the black rook to eliminate the white horse on c3 before it can gallop off and do some damage. White is left with an unpleasant, immobile double-pawn and with holes into which black pieces can easily slide. Sometimes it destroys ... | |
