Checkmate and Clock rule?

Sort:

I played in a USCF rated blitz tournament yesterday and a dispute came up on another board. None of us, including the TD knew the rule.

White had 2 seconds on the clock. He delivered mate before the clock ran out but pushed the button just after it hit 0:00.

My feeling is that mate in the board is the end of the game but what is the actual rule?

The game was called a draw since nobody knew.

Lame Arbiter. Move is not over until you punch your clock!

Even if the move is checkmate? Then you could deliver mate with minutes on the clock and still lose if you never hit the button?

If that is the case then the arbiter made the right call because black had insufficient mating material.

checkmate and stalemate ends the game according to the rule book. i guess the other player could lie if no one was watching

Q:What's a chess clock and how do they work?  A:A chess clock is actually two clocks! When you're thinking, your clock ticks down. After making a move, you hit a button at the top of the clock and your opponent's clock starts ticking. If you run out of time, you lose the game, unless there is checkmate on the board or your opponent has insufficient mating material. There are two main types, the digital and analog clock. that is taken from the faq page on uscf website

White loses. I don't know what the TD was doing, but it was wrong. Even if this were clock move, which it wouldn't be under USCF rules if I recall correctly, this would still be a loss. White flagged. It's that simple.

I am a local TD. USCF rules are clear on this, 13A1,2, and 3. The checkmate is valid if the player did not make the flag claim before the checkmate is delivered. He MUST make the claim. If there is doubt whether the claim is made first or the checkmate , the checkmate takes precedence. In fact there is no claim because the player delivering mate is not required to hit the clock. Checkmate immediately ends the game, as long as it was made by a legal move.

Checkmate precedes if clock claim not made first

I agree.

 White must have won the game.  Checkmate prevails over clock.
