Learn How to Spot Mate in 1: Back Rank Mate
This puzzle is a classic mating net built around king safety and piece coordination. Even in a material-down position, a single forcing move can end the game when the enemy king is boxed in by its own pieces and the escape squares are controlled. The key idea is to look for direct checks on the back rank, especially when rooks or queens can invade with support from long-range pieces. In chess endgame and middlegame positions alike, tactical geometry often outweighs material.
