Learn How to Spot a Fork: Decisive Material Gain
This middlegame puzzle comes from the Sicilian Defense and shows how a single active piece can create a decisive material gain. Black’s pieces are coordinated against a weakened king position, and the key idea is to use a forcing check to drag the king into a vulnerable square. Once the king is displaced, a follow-up fork wins major material by hitting both the king and a high-value piece at once. It’s a classic example of tactical pressure converting into a winning advantage.
