Learn How to Mate in 3: Intermezzo Pin
This middlegame puzzle is a classic example of a forcing kingside attack where tactical geometry matters more than material. White’s pieces coordinate to exploit a pinned defender and an exposed king, turning a seemingly active black position into a mating net. The key idea is an intermezzo check that forces the king into a narrow defensive setup, after which the attack continues with a bishop sacrifice and a final queen invasion. It is a strong example of how pins and discovered threats can decide the game immediately.
