Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical fork that turns activity into a decisive material gain. Black’s rook is ideally placed to create a forcing sequence against the white king and queen, while the white pieces are awkwardly coordinated. The key idea is that a checking move can also attack another valuable target, making defense impossible. In classical chess, these combinations often appear when one side has active rooks and the opponent’s pieces are overloaded.
