Gata Kamsky (Black) Puzzle: Mate — Back Rank

A back rank mate occurs when a king is trapped along its home rank by its own pawns or pieces and cannot step away from a rook’s check. In this chess endgame, White’s active rooks combine to restrict the black king while controlling vital escape squares. The key tactical point is not material alone, but recognizing that Black’s weakened king shelter and limited mobility create an immediate mating net.
