Learn How to Spot Back Rank Mate: Chess Endgame Tactic
This puzzle is a classic back rank mate pattern in a sharp middlegame-to-endgame transition. The defending king is boxed in by its own pawns, leaving the back rank vulnerable to a forcing attack. Even though the material is close, king safety is the deciding factor. The key idea is that a forcing check can drag the king onto a weaker square, after which the final mating move lands with no escape squares available.
