If my opponent moves a piece which put his King in check, but he didn’t realize it and took his hand off the piece what happens now when I show him his mistake?
Also say this exact thing happens but I don’t catch the mistake either and move one of my men - does the game just go on?? What happens If I see the mistake after a few moves?
Thanks!
If your opponent has any legal move with the piece that he touched, then he has to make that move. If not, there is no penalty. The TD also should add two minutes to your clock. If you don’t notice, then as soon as either one of you notices, the game goes back to where it was before the illegal move. Your opponent still has to move the piece if there is any legal way to do so. I wouldn’t add two minutes in this case, because both of you made illegal moves.

Remember that your opponent’s move is not completed until the clock is hit. Up until then he has the option of correcting an illegal move without the two-minute penalty, and if you helpfully point it out to him at that time then he can do so. In any case, touch move would apply (if the touched piece actually has a legal move).
If an illegal move in made and then followed by at least ten more moves by each player (two in quick) then the move is treated the same as if it had been legal and no adjustment of the position is made.
I don’t understand the ‘(two in quick)’ part of your last answer.
Thanks for pointing that out. I was thinking of 16D1 and it is actually 2 moves (by the opponent of the moving player) if less than five minutes remains in the time control. This is a modification of 11B.
If a player releases his hand, the move is complete, no?
I might have to look this up when I get home, but I never thought hitting the clock mattered.
I don’t believe there are separate rules for Quick Chess in terms of number of moves. The reality is that with the vast majority of Quick players not keeping score, a move count requirement is more difficult to enforce.
No. The move is determined.
When he releases his hand in regular chess, the moves is “determined”. It is not complete until he punches the clock. This has many distinctions as regards to other rules. An example is the properly timed draw offer is after your move is determined but before your move is complete to offer a draw.
(See that Terry got the rulebook exact quote right before me)
Yes, but every move that leaves a king in check is illegal, therefore the ten move count has to start over every move, if a player leaves his king in check and neither player notices.
Alex Relyea
Which is why there is a TD Tip that discusses leaving the king in check as opposed to other illegal moves that don’t leave an ongoing illegal position (such as Nf3-d5 if no checks are involved).
Right, but that was the specific question of the OP.
Alex Relyea
Actually, the move isn’t even determined unless it was a LEGAL move, right? So in this particular case the move wasn’t even determined.
Rodney is correct, but I was responding to:
dealing with the common misinterpretation that removal of hand from piece completes a move.
It would probably be fair to say that the player making the illegal move determined what move he or she wanted, but it isn’t a “determined move” as it was illegal. Correct?
The other question this raises… Assume there is a good record of the moves, and you revert the board to first move where the King was put in check (or go back as far as one can reconstruct…)
Edited for clarity:
Is the piece which was first moved illegally, putting the King in check, still required to be moved under touch move (10B?) That is assuming that there are legal moves for the piece unlawfully moved. Or would the player be free to choose any piece to move?
I don’t think you can determine an illegal move-- you can just complete one.
Yes, touch move applies.
Alex Relyea
An illegal move needs to be made legal. Also there is the requirement of touch move as well. So as previously stated if a legal move is available with the touched piece, then it must be made. How this would be done when both King and Rook are touched at the same time, but castling is illegal is another question.
As for the earlier comment about adding two minutes to the clock this does not apply in ALL cases. The rules for adding the two minutes only apply in sudden death and time pressure situations. The only place that the 2 minute addition is listed in the rule book is for sudden death or time pressure. So if the illegal move happens 10 minutes into a game played at 40/90, SD/30 on move 15 there should not be any time added to a player’s clock.

1C2a. Standard penalty.
Except where specifically noted in the rules, the standard penalty assessed by the director is to add two unused minutes to the remaining time of the opponent of the player not following the rules of chess.
1C2b. Non-standard penalties.
Except where specifically noted in the rules, the director may assess penalties either more or less severe than the standard penalty (1C2a). It is often more appropriate for a director to issue a warning(s) before applying 1C2a in cases involving young or inexperienced players. A director may assess a more severe penalty in cases involving players who repeatedly do not follow the rules of chess
I just ordered the 5th edition rulebook, so its in the mail.
According to the posts, if there is less than 5min on the clock, you can only rollback an illegal moves if no more than 2 more moves have been made. [ EDIT: I had to edit that line for it to make sense.]
Personally, I think 5min (or variations based on time delay) chess should have its own rating, and rules specific to blitz ches. I don’t want to debate that in this thread though. I believe that some blitz rules state that if an opponent makes a move that puts his king in check, the opposing player is allowed to capture the king, thus ending the game.
So, its technically legal to put a king in check in blitz chess, its not advisable. Now, these are rules specific to playing chess where the entire game from start to finish is 5min. Pretty sure the rules pre-dated time delay clocks, so not sure if using time-delay clocks, it would be advisable to continue the rule that allows a move that puts your own king in check. But like I said… if you put your king in check and the opponent sees it… you’ve pretty much lost the game.
