Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that wins material by exploiting king safety and loose pieces. White’s knight jumps into an active square with tempo, forcing the king to respond while simultaneously attacking multiple high-value targets. The key idea is not a flashy mating attack, but a tactical refutation that overloads Black’s coordination. When the opponent’s queen, bishop, or rook is tied to defense, a fork can convert activity into a decisive material gain.
