Learn How to Fork: Decisive Material Gain

This middlegame puzzle comes from the Benoni Defense and shows how a forcing queen check can create a crushing tactical fork. White’s pieces are active, Black’s king is still exposed in the center, and the loose bishop on b4 adds to the tactical vulnerability. The key idea is not a long strategic buildup, but a short, forcing sequence that wins material by combining check, piece activity, and a discovered attack on the queen-side cluster.
