Learn How to Spot Mate in 1: Back Rank Tactic
This puzzle is a classic example of a forcing tactical finish in the middlegame, where king safety matters more than material. Even though one side may be ahead on the board, an exposed king and limited escape squares can decide the game instantly. The key idea is to look for direct checks first, then ask whether the king has any legal flight squares or defensive interpositions. When those resources are gone, a single rook or bishop can end the game immediately.
