Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical refutation based on a knight fork. White’s active knight jumps into the enemy camp, creating a direct check while simultaneously attacking major pieces. The key idea is that one forcing move can overload the defender and expose a trapped queen or rook. In positions like this, material balance matters less than piece coordination: a well-timed fork can turn a losing-looking position into a winning combination with decisive material gain.
