| Posted by rich_sposato goclub.org 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 goclub.org 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 goclub.org 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 ——— Endgames, part 1: Rook against Bishop — A superb lesson from Magnus Carlsen in endgame technique. It's been a while since we looked at the endgame, so this week we begin a short series on this often neglected area with a terrific demonstration of endgame technique from the ever-improving chess world No 1 Magnus Carlsen. Although White has the advantage of rook against bishop, Black has an extra pawn and a solid position on the chess board. How did Carlsen make progress? RB I'm pretty sure the answer lies in g4. The question is whether to nudge the pawn forward immediately or whether some preparation is needed first, perhaps exchanging on d5 or advancing the king to e3. The only way is concrete calculation, so let's see what ... Posted by chessnovice | goclub.org 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." ——— Dortmund Begins — The Sparkassen Chess-Meeting (an odd name, to be sure) began Thursday in Dortmund. Though the chess tournament is not at the level of Linares or Corus, it still attracts top players, notably Vladimir Kramnik, the former world chess champion from Russia. Kramnik has been associated with Dortmund, as the chess event is often referred to, for many years because he has won the tournament nine times, far more than any other. He first won it in 1995 and is the defending champion this year. The tournament is a double-round robin this year, meaning each competitor plays all the others twice, once with each color. In addition to Kramnik, the No. 4 chess player in the world, the field includes ...

The two chess tournaments are being held concurrently at the Chess Club and Scholastic Center of Saint Louis. Zatonskih had shared the lead for the last few rounds with Irina Krush, the top seed. But in Round 5 on Wednesday, Zatonskih beat Iryna Zenyuk, while Krush only drew against Camilla Baginskaite. Zatonskih now leads with 4.5 points, while Krush and Tatev Abrahamyan, who beat Abby Marshall on Wednesday, have 4 each. In the junior championship, Zhao, who ... Posted by kinderboy | goclub.org 9/01/2008 15:18:46 Play online chess ITS NOT LEGAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Message: ——— A Chess Odyssey — One single square can make a big difference in a chess game. It helped me to launch one of my longest combinations against Anatoly Karpov in Caracas 40 years ago. It was a memorable chess tournament for both of us. Karpov arrived in Venezuela as the reigning world junior champion. He played well enough in Caracas to become the world's youngest chess grandmaster at that time, at age 19, and his brilliant career began to take shape. In 1971 in Moscow, he clinched the first major tournament victory, sharing first place with the three-time Soviet champion Leonid Stein at the prestigious Alekhine Memorial tournament. In 1975 he was crowned the world chess champion. This year ... Posted by throneseeker | goclub.org 10/09/2008 19:35:25 Play online chess CastlingMessage: The short answer to the question is NO as has been stated in a variety of fashions. ——— Fast Pace Continues at Two U.S. Chess Championships — The top two seeds in the U.S. Women’s Chess Championship could make no headway against each other and drew their Round 3 game on Monday. But their two nearest competitors lost, so Irina Krush and Anna Zatonskih now lead the chess tournament by half a point over Tatev Abrahamyan, Alisa Melekhina (who lost to Abrahamyan on Monday) and Iryna Zenyuk, who lost on Monday to Beatriz Marinello. In the U.S. Junior Chess Championship, which is being held concurrently at the Chess Club and Scholastic Center of Saint Louis, Warren Harper, the seventh seed, is the surprising leader after three rounds with a perfect score. His play so far has been stellar and on Monday he demolished his ... Posted by tugger | goclub.org 10/10/2008 09:45:34 Play online chess NO Message: Posted by ccmcacollister | goclub.org 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. |
