Learn How to Win with a Fork: Decisive Material Gain
This puzzle comes from the Petrov's Defense and shows a classic opening tactic where active piece placement creates a decisive material gain. Black’s knight jumps into the center with tempo, attacking multiple white pieces at once and forcing the king into an awkward response. The key idea is that a single forcing move can combine check, fork, and piece activity to win a major piece. In classical chess, these tactical shots often decide the middlegame before development is complete.
