Hook Mate Intermediate Puzzle (Rated 1181): Spot Hook Mate — Mate in 1

This chess endgame puzzle is a classic hook mate pattern: the enemy king is boxed in by its own pieces and pawns, while a rook delivers the final blow from a key file or rank. In these positions, the mating piece often works because the king has no flight squares and every escape is covered. The position also shows how a pinned pawn and a skewer can create a forced finish in classical chess.
