Learn How to Win a Fork: Decisive Material Gain
This middlegame puzzle shows how a single active knight can create a decisive material gain by attacking multiple targets at once. In the Accelerated London System, piece activity and king safety often matter more than static material count, and here Black’s pieces coordinate to exploit loose white pieces and an exposed king. The key idea is a forcing tactical sequence that wins material through a fork, not a quiet positional maneuver. Recognizing these moments is a core classical chess skill.
