French Defense Knight Variation Puzzle (Rated 968): Crush with a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a crushing fork that wins material by forcing the king into a bad square and then exploiting the loose pieces around it. Black’s active pieces coordinate against White’s king and queen, creating a tactical sequence where one forcing check opens the door to a decisive capture. The key idea is not just the fork itself, but the follow-up that keeps White under pressure and converts the initiative into a winning material edge.
