Learn How to Fork: Decisive Material Gain
This middlegame puzzle shows a classic tactical refutation in the Sicilian Defense: a knight jump creates a fork against the queen and rook while also exposing loose pieces around the king. The position is not about a mating attack, but about forcing a decisive material gain through piece activity and king safety pressure. When the opponent’s pieces are uncoordinated, a single forcing move can turn a balanced game into a winning one.
