Learn How to Win Material: Fork Tactic
This middlegame puzzle is a classic example of a tactical refutation based on king safety and piece activity. White’s queen invades with tempo, forcing the black king to respond while also targeting loose material. The key idea is that the checking move creates a fork-like pressure on multiple vulnerable pieces, leaving Black unable to defend everything at once. In practical classical chess, these positions often arise when one side’s king is slightly exposed and the opponent’s pieces are already active.
