Learn How to Spot Mate in 1: Back Rank Mate
This middlegame chess puzzle is a classic example of king safety deciding the game immediately. White’s rook is active on the seventh rank, the bishop supports the attack from a long diagonal, and Black’s king is boxed in with limited escape squares. When a rook can invade the back rank with support, even a material deficit can disappear in a single tactical blow. These positions reward alertness to mating nets, pins, and overloaded defenders.
