Learn How to Spot Back Rank Mate: Mate in 1
This middlegame puzzle is a classic example of a back rank mate: the king is boxed in by its own pieces and cannot create luft, while a rook on an open file can deliver the final blow. The position also shows how hanging pieces and pinned defenders can make a seemingly active defense collapse instantly. Even when one side is materially ahead, king safety can outweigh everything if the back rank is weak and the key escape squares are covered.
