| Posted by rich_sposato blitzbrain.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 premium_steve blitzbrain.com 6/29/2008 21:47:49 Play online 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 blitzbrain.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 ——— London Chess Classic: Kramnik's lesson in positional play — McShane-Kramnik, London 2009. Black to play. With two rounds to go in the London Chess Classic, the Norwegian chess prodigy Magnus Carlsen looks set to win the tournament. Vladimir Kramnik, his main rival, is in second place. In this game from round three, Kramnik displayed his refined positional understanding. RB I've been following this tournament online, but I missed this particular game, and more's the pity because I can't find a good continuation for Black. Clearly Kramnik has the better game – the two centralised knights look very threatening – but how to convert Black's positional superiority into a winning position? 1...Nxd2 2 Nxd2 doesn't lead anywhere and ... Posted by chessnovice | blitzbrain.com 6/30/2008 10:18:33 Play online 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." ——— Gelfand Wins World Chess Cup — Boris Gelfand of Israel is the 2009 World Cup champion. Gelfand won the title by beating Ruslan Ponomariov of Ukraine in a playoff on Monday. The first four games of the playoff were rapid games (25 minutes per player per game) and Gelfand took the lead by winning the second game. But Ponomariov, with his back to the wall, won the last rapid game to tie the match up again. The playoff then went to blitz chess (5 minutes per player per game) and Gelfand once again took the lead by beating Ponomariov in the first game when he managed to trap Ponomariov’s queen in 21 moves. Ponomariov rallied again, winning the second game. But Gelfand won the third and Ponomariov ...

By the luck of draw, they met in the first round, and Carlsen won. The Norwegian GM was still in a clear lead on Sunday with four points in five rounds, a full point ahead of Kramnik. U.S. chess champion Hikaru Nakamura drew four games and lost one. The tournament concludes Tuesday. The Carlsen-Kramnik duel looked like a perfectly played game by the Norwegian, who took advantage of Kramnik's stranded knight. "If one piece is ...

That is what happened between Nigel Short and Luke McShane of England in the first round of the London Chess Classic, which started on Tuesday. McShane, who had White, got a tiny advantage out of the opening, but Short defended well, and after 60 moves it seemed as if the game would end in a draw. But McShane, 25, persisted and Short, 44, was forced to continue to defend. It took McShane seven hours, and 163 moves, but he finally broke Short and forced him to resign. That ...

When the field of 128 was reduced to the quarter-finals in the current World Chess Cup, all eight grandmasters remaining had their education from Soviet coaches. The final four-game match now in progress to decide who qualifies for the 2010 candidates is between Ukraine's Ruslan Ponomariov, who won the 2002 World Cup as a teenager, and Boris Gelfand, the 41-year-old top seed. In the semi-finals Ponomariov beat Vlad Malakhov 4-2 while Gelfand eliminated Sergey Karjakin 2-0. In both the semi-final and in the game below the Israeli chess veteran defeated ...

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. |
