Learn How to Fork: Decisive Material Gain
This middlegame puzzle shows how a single forcing move can convert activity into a decisive material gain. Black’s queen enters with tempo, creating a check that also attacks loose pieces and exposes the white king’s limited shelter. The position is a classic example of tactical coordination: the king is forced to move, and then the queen can capture a key piece while maintaining the initiative. In practical classical chess, these moments often decide the game immediately.
