Learn How to Spot Mate in 1: Bishop Checkmate
This puzzle is a classic mate in 1 example from a middlegame position, where king safety matters more than material. White’s pieces are already aimed at the enemy king, and the final blow comes from a bishop on a powerful diagonal. The key idea is that a checking move can also be a mating move when every escape square is covered and the king cannot capture the attacker or interpose a defender.
