Shah Mat, commonly known as checkmate, is a term used in the game of chess to indicate that a player's king is in a position to be captured and cannot escape. The objective of chess is to checkmate the opponent's king, thereby winning the game. This situation arises when the king is under direct attack and has no legal moves to evade capture. The term "Shah Mat" originates from Persian, meaning "the king is dead." It reflects the game's strategic nature, where players must anticipate their opponent's moves while protecting their own king. Mastering the concept of checkmate is essential for success in chess.
