Learn How to Win a Fork: Decisive Material Gain
This puzzle comes from the French Defense and shows a classic opening tactic where active piece placement creates a decisive material gain. White’s bishop and knights coordinate to pressure the black king and the pinned knight on c6, turning a normal-looking development battle into a tactical problem. The key idea is that when a piece is pinned to the king, it often cannot move to defend other targets, so a forcing check can win material by exploiting that restriction.
