Learn How to Spot Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a back rank mate pattern. White’s king is boxed in by its own pieces and pawns, while Black’s heavy piece activity creates a direct mating net. In positions like this, the key idea is to look for the most forcing move first: checks that exploit a cramped king, especially when escape squares are covered and defensive pieces are overloaded or pinned. The tactic works because the king has no safe flight square and the line to mate is already open.
