Learn How to Spot Opera Mate: Mate in 3
This middlegame puzzle is a classic mating attack built around an exposed king, a pin, and a forcing sacrifice. White’s king is stuck in the center, and Black’s heavy pieces are lined up to exploit the open files around it. The key idea is to use a forcing check that drags the king into a worse square, then bring the rook in with tempo. Once the defender is overloaded, the final mating net becomes unavoidable.
