What is checkmate meaning?

Checkmate is a term used in the game of chess to indicate a winning position where the opponent's king is under attack and there is no legal move to avoid or block the attack. It ends the game and the player who achieves checkmate is declared the winner. The term checkmate comes from the Persian phrase "shah mat," which means "the king is defeated" or "the king is helpless". It is an important concept in chess strategy, and players often strive to create situations where they can deliver checkmate to their opponents.
