Learn How to Fork Long Mate: Mate in 3
This middlegame puzzle is a classic example of tactical pressure turning into a forced mating net. White’s active queen and knight coordinate against the enemy king, while the defender pieces are overloaded and unable to cover every threat at once. The key idea is to use a forcing check that also creates a fork-like threat, driving the king into a cramped defensive setup. Once the king is restricted, the attack finishes with a precise queen-and-knight sequence.
