Illegal move in blitz games

[Erwin Casareno]

I brought up this topic here in chess talk so that the knowledgeable people on this topic can reply to this post and clear up things.

Blitz is my favorite game and with plans brewing up for an every Friday night blitz tournament in downtown Toronto, we need to make things clear.

1. Case 1: The opponent plays an illegal move, which exposes the king to a check/ or has ignored a check, and has punched his clock.

Question: Can i claim a win here?

In the Brampton chess club, their rule is to replay the move and 2 minutes added to your clock as penalty to your opponent.

On the second infraction, a win is awarded.

In the Netherlands, you have to claim the win immediately. You do not need to move any piece. This is a win even if the opponent has not punched the clock.

Note also that, in the Netherlands, you are not allowed to take/capture the king in blitz play. Otherwise, you are the one charged with the illegal move. This happened to me once against Raymond Liem 2200+ on the En Passant coffee house in The Hague.

2. Case 2: The illegal move is caused by a knight moving like a bishop, or a bishop changing color of squares as it moved, or other cases which does not involve a king check.

Question: Can a win be claimed? What is the normal rule to this case?

In the Netherlands, an illegal move is an illegal move, and a win is claimed right away.

Thank you to anyone to reply who has knowledge of FIDE rules.

If you are replying based on your opinion, please clearly indicate that this is an OPINION only.

Re: Illegal move in blitz games

It looks like Netherlands uses FIDE blitz rules, which are usually used in Montreal blitz tournaments (unless an announcement is made allowing King chops).

Another situation: a player knocks over one (or more) pieces, and replaces one (or more) on the wrong squares, and completes his move by pressing the clock. Can the opponent claim that the player made two moves (the original legal move, and a "move" made by replacing a piece on a wrong sqaure)?

In both cases the illegal moves were made (assuming that in the Case 2 the clock was pressed too). The results depend on concrete positions, see FIDE rules

"B.3
3. An illegal move is completed once the opponent’s clock has been started. The opponent is entitled to claim a win before he has made his own move. However, if the opponent cannot checkmate the player’s king by any possible series of legal moves, then the claimant is entitled to claim a draw before he has made his own move. Once the opponent has made his own move, an illegal move cannot be corrected unless mutually agreed without intervention of an arbiter."

This probably might be ruled with

7.3 If a player displaces one or more pieces, he shall re-establish the correct position on his own time. If necessary, either the player or his opponent shall stop the clocks and ask for the arbiter’s assistance. The arbiter may penalise the player who displaced the pieces.

Re: Illegal move in blitz games

For blitz, the outcome of an illegal move depends on the supervision. For supervised blitz, we use the rules of regular game : plus two minutes to the opponent for the first two illegal moves and loss of the game for the third illegal move by the same player during the same game.

For unsupervised blitz, a properly claimed illegal move loose instantly unless the claimant cannot checkmate his opponent by any series of legal moves in which case the game is drawn. An unclaimed illegal move cannot be corrected later unless both players agree without the intervention of the arbiter.

B.3
Where supervision is inadequate the following shall apply:

a. Play shall be governed by the Rapidplay Laws as in Appendix A except where they are overridden by the following Laws of Blitz.

b. Article 10.2 and Appendix A.4.c do not apply.

c. An illegal move is completed once the opponent’s clock has been started. The opponent is entitled to claim a win before he has made his own move. However, if the opponent cannot checkmate the player’s king by any possible series of legal moves, then the claimant is entitled to claim a draw before he has made his own move. Once the opponent has made his own move, an illegal move cannot be corrected unless mutually agreed without intervention of an arbiter.
