In the game of chess, checkmate occurs when one player’s king is under immediate threat of capture (check) and there is no legal move to remove that threat. Checkmate signifies the end of the game, with the player delivering checkmate declared the winner.
While various pieces can contribute to checkmate, a particularly notable scenario involves using a rook and king. A rook is a powerful piece that can move horizontally or vertically any number of squares, while the king can move one square in any direction.
