Learn How to Mate in 1: Back Rank Mate
This chess endgame puzzle is a classic one-move finish built around a back rank mate pattern. White’s rook has access to the open d-file, and Black’s king is boxed in by its own pieces and pawns. The key idea is that the checking piece lands on the back rank with no escape squares available. The position also features a pin on the queen, which helps keep the defense from coordinating in time.
