Sacrifice Puzzle (Rated 1435): Spot Mate in 2 — Back Rank Mate

This chess puzzle is a classic forcing finish where the attacking side uses a sacrifice to drag the enemy king onto a vulnerable square and then deliver mate on the back rank. The key idea is attraction: the king is lured away from safety so a rook can invade with decisive force. Even in a middlegame-like position, the pattern feels like a clean chess endgame tactic because the pieces are coordinated and the king has almost no escape squares.
