In chess, the term "endgame" refers to the final phase of a game, where few pieces remain on the board. This stage focuses on promoting pawns to queens and achieving checkmate. Players must use their remaining pieces strategically to control key squares and create winning opportunities. Endgames often involve specific techniques and principles, such as king and pawn endings or rook endgames. Understanding these concepts is crucial for players to convert advantages into victories or to hold a draw in challenging positions. Mastery of endgame strategies can significantly improve overall chess performance.
