Learn How to Spot Mate in 1: Bishop Sacrifice
This puzzle is a classic middlegame mating pattern where a bishop sacrifice finishes the game immediately. The key idea is that the enemy king is boxed in by its own pieces, so a checking move can become an epaulette mate: the king has no safe escape squares and no way to capture the attacking piece. Even though material may be uneven, king safety overrides everything when the mating net is already complete.
