Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a fork tactic creating a decisive material gain. White’s active knight jumps into the enemy camp with tempo, forcing the king to respond while also attacking a valuable target. The key idea is not just the check itself, but the follow-up that keeps the initiative and converts activity into real material. In practical chess, these tactical shots often appear when the opponent’s pieces are loose and the king is slightly exposed.
