Four Knights Game Scotch Variation Pin Puzzle (Rated 1382): Spot a Mate in 1 — Back Rank Mate

This chess endgame puzzle is a classic example of a back rank mate, where the enemy king is boxed in by its own pieces and pawns. White’s rook is ideally placed on the open file, and the black king has no safe flight squares because the back rank is cramped. In positions like this, active rook placement and king safety matter more than material count, turning a quiet-looking board into a forced finish.
