Learn How to Spot Back Rank Mate: Mate in 3
This chess puzzle is a classic example of a back rank mate pattern in a sharp middlegame-to-endgame transition. The key idea is that the defending king is boxed in by its own pieces and pawns, leaving the back rank vulnerable to a forcing attack. Even when the material balance looks playable, king safety can outweigh everything else. The attacking side uses forcing checks and a sacrifice to remove the last defender and create a mating net.
