Anatoly Karpov (Black) Puzzle: Mate — Pawn Checkmate
A chess endgame can end abruptly when an advanced pawn joins the attack. Here, Black’s active rook and bishop restrict the white king while the centralized pawn provides the final tactical resource. This is a David-and-Goliath mate: the least powerful unit delivers the decisive blow because stronger pieces have already sealed the escape squares. Material matters, but coordinated king pressure matters more when every legal reply has been removed.
