Vassily Smyslov (Black) Puzzle: Back Rank Mate — Rook
A back rank mate occurs when a king is trapped by its own pieces or pawns and an enemy rook or queen delivers check along the home rank. In this position, Black exploits White’s restricted king, active rooks, and a pinned bishop near the king. The key tactical idea is to use a forcing check that removes a defender and creates an unavoidable second attack. Material advantages become irrelevant when king safety allows a direct mating pattern.
