Learn How to Spot Mate in 1: Bishop Check
This middlegame puzzle shows how a single bishop move can end the game when the enemy king is underdeveloped and boxed in. White has a major development lead, active pieces, and pressure along the e-file and dark squares, while Black’s king remains exposed in the center. The key idea is that a quiet-looking bishop placement can become a direct mating move when every escape square is covered and the defending pieces are too passive to help.
