Bishop's Opening Boi Variation Puzzle (Rated 899): Fork — Winning Material

This middlegame puzzle is a classic example of a tactical fork that creates a decisive material gain. Black’s knight jump hits multiple high-value targets at once, exploiting loose coordination and a vulnerable king zone. The key idea is that a forcing check can also be a fork, turning defense into damage. Once the king is forced to move, the follow-up wins a major piece and leaves White unable to untangle the position.
