Never .. Ever
a false checkmate is when someone calls "checkmate" in a chess game and if you can move without getting out then it is a false checkmate. If they call it you get to go 2 times. :) enjoy your chess game!
Checkmate is a possible outcome for a game of chess.
The word checkmate in chess comes from the Persian phrase "Shah Mat" which means: 'the king is dead.'
Checkmate your Opponents King
George Koltanowski has written: 'Adventures of a chess master' -- subject(s): Chess, Schaken, Blind schaken 'With the chess masters' -- subject(s): Chess 'Checkmate!' -- subject(s): Checkmate (Chess)
The last move in chess is a checkmate. A checkmate is when you have trapped the king to where it cannot escape in anyway. Then, you win the game.
