Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a forcing tactical shot that turns activity into a decisive material gain. The key idea is to use a check that also creates a fork, so the opponent’s king is forced into a narrow response while an important piece becomes vulnerable. In positions like this, active pieces and loose defenders often outweigh static material, especially when the enemy queen or knight is overloaded and the king’s escape squares are limited.
