Endgame

The endgame is the phase that usually follows the middlegame after many pieces have been exchanged. Not every game reaches it, and there is no exact threshold. The nature of the position matters more than the move number or the simple absence of queens.

With fewer pieces able to organize a mating attack, the king can leave its shelter and become an active piece. It can block the opposing king, support pawns, attack weaknesses, and occupy decisive squares. This activity still requires calculation because positions with queens or rooks may contain dangerous checks.

Pawns gain importance because reaching the last rank allows promotion to a queen, rook, bishop, or knight. A single square, one move of timing, or the side to move can change the result completely. Endgames therefore demand precision even when few pieces remain.

Ideas such as zugzwang also become prominent. Zugzwang is a position in which every legal move worsens the situation of the player to move. Exchanges must be judged by the resulting ending: simplification can secure a win, but it can also remove the last winning chances or make defense easier.

Endgame technique combines general principles with exact positions. Activating the king and advancing a pawn are common goals, but checks, captures, promotion races, and drawing resources must be calculated first.
