Grob Opening Intermediate Puzzle (Rated 1024): Fork — Decisive Material Gain

This middlegame puzzle shows how a forcing tactical idea can turn a strong position into a decisive material gain. The key is recognizing when a knight jump creates a fork against major pieces while also keeping the initiative. In classical chess, these moments often arise after the opponent’s king is exposed and their pieces are overloaded. The position rewards calculation, not slow maneuvering, because the tactical shot wins time, material, and coordination at once.
