Learn How to Fork: Winning Material
This puzzle comes from the Pirc Defense and shows a classic middlegame tactical refutation. White’s pieces are active, but Black can turn the tables by using forcing moves that create a fork and attack multiple targets at once. The key idea is to combine check with piece activity so the opponent’s king is forced into a passive square while a major piece becomes vulnerable. In practical classical chess, these short tactical sequences often decide the game immediately.
