Learn How to Fork: Decisive Material Gain
This middlegame puzzle from the Dutch Defense shows how a forcing check can expose loose pieces and create a winning tactical sequence. White’s active queen and knight coordinate against the black king’s position, while Black’s pieces are overextended and poorly coordinated. The key idea is to use tempo-gaining moves to keep the defender tied up, then exploit the forked targets and the trapped piece on the queenside. It is a classic example of converting activity into decisive material gain.
