Learn How to Double Bishop Mate: Mate in 1
This puzzle is a classic middlegame mating net where bishop activity overwhelms the exposed king. The key idea is to use coordinated diagonals to attack the king with a forcing check that cannot be met by capture, block, or escape. Positions like this reward players who notice king safety first: loose pieces, an uncastled king, and open lines often make a direct finish possible even when material is otherwise balanced.
