The chess endgame is the final phase of a chess game, occurring after most pieces have been exchanged. In this stage, players focus on promoting pawns and checkmating the opponent's king. Understanding key endgame principles is crucial for converting advantages into victories. Endgames often involve fewer pieces, making precise calculation and technique essential. Common endgame scenarios include king and pawn versus king, and various rook endgames. Mastering these situations can significantly improve a player's overall chess skills and increase their chances of winning games.
