Learn How to Spot Double Bishop Mate: Mate in 1
This puzzle is a classic middlegame mating net where active bishops coordinate to attack the king on dark and light squares at the same time. In positions like this, material can be irrelevant if the enemy king is boxed in and key escape squares are covered. The lesson is to look for forcing checks first, especially when a bishop can strike through the center or along a long diagonal and the king has limited flight squares.
