Learn How to Spot Mate in 1: Bishop Checkmate

This middlegame puzzle comes from the English Opening and shows how a single bishop can finish a game when the enemy king is exposed. The key idea is that checkmate is possible because the king’s escape squares are restricted and the attacking pieces already control the critical lines. In classical chess, these patterns often appear after development leads to a direct king-side attack, especially when the opponent’s pieces are too passive to help defend.
