If someone makes a move that exposes their king to check, and this is not noticed, and it is now several or more moves later (and you don't remember exactly what the moves were) and this king is sitting there in check, what do you do?

Here is the FIDE rule (from http://www.fide.com/official/handbook.asp?level=EE101)

If during a game it is found that an illegal move has been made, the position immediately before the irregularity shall be reinstated. If the position immediately before the irregularity cannot be determined the game shall continue from the last identifiable position prior to the irregularity.

It seems like there is not a very good way to deal with this. If it is my move, and the other player's king has been left in check, I don't take the king and end the game? I hate the idea of having to "guess" where pieces where, because you know the game got screwed up at this point. I wonder if it would be better to just start a new game

This happenned to me in a blitz game recently - I thought that my opponent made a bishop move with his knight. Then we realized that neither of us knew where the knight had come from. Starting a new game was all we could do.
For longer time limits writing down the moves gets round the problem.

No.. you can't take the king and end the game, because you were to announce check .. there is no sneak king captures in chess.. both players must know that the king is in check, and any moves after that doesn't remove the check situation is considered illegal.

A lot of people I know play blitz without saying check. If you don't spot it they take the king and the game is over.

Then they're not playing chess.

You don't have to announce check, but when your opponent moves while he's in check you can either:
- capture the king (don't know if this is legal)
- claim (probably only some time)
- hit the clock and tell him to make another move

You dont have to announce check. Infact if you were doing it everytime say when you had my king on the run id ask the arbiter to tell you to shut up :-)

I never announce check, if they cant see there king is in check and they pick up another piece im going for touch move rule. With any luck they might have to drop there queen infont of their king for my bishop or something to snap up :-)

Maybe announce check was incorrect.. what I mean though, is that the person can't make a play until the check has been removed.. so.. if they don't know they are in check, someone has to tell them.. else all moves after that are invalid..

my way:

fast play ... just take the king; and consider it a win ... there can be no time for negotiation: the wrong players clock is ticking ... you can play a whole new game instead.

slow play ... try to encourage "touch piece - move piece" style of play, and avoid taking back moves ... some opponents insist on taking back moves: i say ok, but dont play them often again ... if a check is not noticed in a slow game then i wonder at our levels of keenness and concentration and intoxication.

No it is chess. Official FIDE blitz rules specifically state king captures end the game. Check does not need to be announced at any time control. You can check the rules and which time controls constitute blitz on www.fide.com.

That's been the rule of blitz for as long as I can remember.
