Learn How to Win Material: Fork Tactic
This middlegame puzzle shows a classic tactical refutation in the English Opening: one active piece jumps into the center to create a fork and win material. The key idea is that a seemingly strong attacking setup can collapse when the king is forced to move and a loose piece becomes vulnerable. In positions like this, the side to move often has a forcing sequence that combines check, tempo, and material gain rather than a direct mating attack.
