Learn How to Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a mating net built around king safety. White’s heavy pieces are active on open files, and the black king is stuck in the center with limited escape squares. When a rook can invade the back rank, the defender’s pieces and pawns often become irrelevant because the king is boxed in by its own army. These positions reward fast calculation and a sharp eye for direct threats.
