Learn How to Spot Mate in 1: Bishop Mate
This puzzle is a classic middlegame mate in 1, where the attacking side has already built a mating net around the enemy king. The key idea is not material, but king safety: the defending pieces are overloaded, the king has limited escape squares, and a bishop can deliver the final blow on a diagonal. In classical chess, these short tactical finishes often come from active pieces coordinating against a centralized king.
