Learn How to Spot Mate in 1: Bishop Check
This puzzle comes from the King's Gambit Declined and shows a classic middlegame mating net where piece activity matters more than material. White’s queen and bishop coordinate against the black king, which is stuck in the center and short of safe squares. The key idea is to recognize when an active bishop can deliver a direct finishing blow because the enemy king’s defenders are overloaded, pinned, or simply too far away to help.
