Mate In 1 Puzzle (Rated 888): Spot Mate in 1 — Chess Endgame

This chess endgame puzzle is a pure tactical finish: the side to move has a direct checkmate available, so calculation matters more than long-term strategy. Even in a simplified position, king safety can decide everything when the enemy king is boxed in by its own pieces and pawns. In classical chess, these moments reward players who scan forcing moves first, especially checks that restrict escape squares and exploit weak king shelter.
