Elephant Gambit Hanging Piece Puzzle (Rated 1015): Spot Back Rank Mate — Mate in 1

This middlegame puzzle is a classic example of a back rank mate pattern, where the enemy king is boxed in by its own pawns and pieces. Even when material is uneven, the decisive idea is often a direct mating attack on the first rank. Here, the key tactical motif is a forcing rook move that exploits the open file and the vulnerable king position. It is a great reminder that king safety can outweigh material in classical chess.
