| Posted by rich_sposato uskidscompute.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 uskidscompute.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. :) | ||||||||||||

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 ——— Topalov Takes on the Irish National Team — When elite chess competitors take on a number of weaker opponents in simultaneous exhibitions, the stronger chess player has to move from board to board and has little time to formulate strategies. Rarely are the weaker players even on the master level. But in the 1980s, Garry Kasparov, who was then world chess champion, began giving exhibitions in which he took on groups of top-level chess players. They were timed, so Kasparov had to move faster than his opponents. After losing the first of the so-called simuls against a strong club team from Germany in 1985, Kasparov won every other one he played. Between 1987, when he won a return match against the Germans, and 2001, when he beat ...

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." ——— Vasily Ivanchuk seizes on rivals' blunders to lead Grand Slam final — In a rare form upset both the world chess champion, Vishy Anand, and the world No1, Magnus Carlsen, were beaten on the same day at the Grand Slam final which has just switched from São Paulo, Brazil, to Bilbao, Spain, for its last five rounds. Anand got his queen trapped while Carlsen made a mega-blunder which is featured in this week's puzzle. The major beneficiary was Vasily Ivanchuk, 42, who beat both Anand and the world No3, Levon Aronian, and since the chess event is using football-style three points for a win he was briefly six points clear until losing to Carlsen in the final São Paulo round. It seemed that Ivanchuk would have fond memories of São Paulo but next day, as ...

At first, it was looked upon with suspicion: giving white a strong pawn center that could only be tickled by black's dark bishop and other chess pieces didn't seem to be a fair deal. Those who played the Grunfeld defense knew that it could turn into a nightmare in an instant. But the defense also brought them bright moments, tempted them again and again, and they could not live without it. Bobby Fischer created the "game of the century" in 1956 against Donald Byrne and he almost beat the world chess champion Mikhail Botvinnik at the 1962 olympiad in Varna, Bulgaria, with the Grunfeld ... Posted by kinderboy | uskidscompute.com 9/01/2008 15:18:46 Play online chess ITS NOT LEGAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Message: ——— Chess piece value — When I teach a class of beginning players, it is customary to explain the “value” of the chess pieces. If both sides exchange pieces, knowing their approximate value will help explain who gets the better deal. Some things are pretty obvious, like if I capture a queen and my opponent captures a bishop, we both know who is doing better. But some things are not so clear. I try to make analogies when I teach. Some hit the mark, and some confuse the student even more! But before I try to confuse my readers, let us look at standard values: Queen = 9, Rook = 5, Bishop = 3, Knight = 3, Pawn = 1. The king does not have a capture value, since we do not capture the king. (You can’t say, “I captured his knight and two pawns for...

White has come out of the opening with a certain spatial advantage. Now he has to find a plan. Warning: you're not looking for a sacrificial combination – this is Karpovian, it's all about subtlety and strategy. RB: I've nominated Karpov's Strategic Wins 1: The Making of a Champion by Tibor Karolyi (Quality Chess) for our book of the year award. It's a year-on-year account of Karpov's career from 1961 to 1985, nicely laid out and well annotated. Karpov's style is positional, unhurried and exceptionally deep. Constantly alert to the counter-stroke, he likes to make small improving moves. Some of Karpov's choices remain, even with the help of a chess computer, mysterious, as ...

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. |
