Learn How to Spot: Double Bishop Mate
This puzzle is a classic middlegame mating net where bishop coordination overwhelms the king. The key idea is that two bishops can control adjacent escape squares and create a direct checkmate when the enemy king is exposed. In positions like this, material count matters less than king safety, piece activity, and the geometry of the board. Even a seemingly modest move can become decisive if it attacks the king on a vulnerable diagonal and removes every flight square.
