Castle after check...?

Sort:

Hi...just played a live game...opponent on the 5th move was in check...he later castled...is this allowed?...the computer allowed it...but I thought it was illegal?...I'm probably wrong as I lost, but was relying on him not being allowed to castle? http://www.chess.com/livechess/game.html?id=202265801

Having been checked does not strip castling privileges down the road.

Giving check doesn't necessarily take away your opponent's castling rights for future moves.  However, when he does castle, he cannot be in check, go through check or end up in check.

You can't castle when you are in check, you can't castle across check, you can't castle when your King or the Rook has moved, but you can castle when you have previouslly been in check.

Four requirements must be fulfilled in order to castle:

1) The king and the rook used for castling must not have moved previously, even if they are at their initial positions;

2) All squares between the rook and the king must be empty;

3) The king must not be in check and

4) None of the opponent's pieces can control any square between the king and his destination square (included).

Just a remark for the fourth requirement: only in the long castle there is a square between the rook and the king which can be under control by an enemy piece, which is that next to the rook (the king doesn't "pass" there, but this idea of passing doesn't please me, as the king doesn't move "while" castling. Castle is one of the three special moves in chess, along with en passant and pawn promotion, and happens all at once - you "replace" the king and the rook in the same move).

But the King can't "move" through check because it would be as if he had landed on those squares, so it is "passing"? Isn't it? If it was "replacing" then the King wouldn't need to worry about "moving" through check. The same with en passant, which of course means in passing. I am just making this comment for the sake of logic and interesting discussion tongue.png

Old timers: Has this rule changed in living memory? I was 100% certain you couldn’t castle after previous being in check!

The rules around that haven't changed since the 1800's as far as I'm aware. Some people confuse actual rules to mean something they don't. For example, they heat "can't castle out if check" and think that means that castling isn't possible after check
