Learn How to Spot a Mate in 1: Bishop Trap

This puzzle is a classic middlegame mating pattern from the Queen's Gambit Declined, where Black’s pieces coordinate against a vulnerable king in the center. The key idea is not material, but king safety: one bishop can create a direct mating net by using the open lines and weak squares around the white king. In classical chess, these motifs often appear when development leads and the opponent’s king has no safe escape squares.
