Learn How to Spot Double Bishop Mate: English Opening Puzzle
This middlegame puzzle comes from the English Opening, where piece activity and king safety matter more than raw material. White is behind in material, but the black king is exposed and the dark-square weaknesses around it are severe. In positions like this, bishops can become lethal attacking pieces because they control long diagonals and coordinate with the queen and rook to restrict escape squares. The key lesson is that a direct mating net can outweigh a material deficit when the enemy king lacks shelter.
