Queens Pawn Game Accelerated London System Fork Beginner Puzzle (Rated 851): Win a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a tactical fork that wins material by exploiting piece activity and king safety. White’s active rook and bishop create pressure, but Black’s counterplay comes from a forcing knight jump that checks the king and attacks key pieces at the same time. In classical chess, these moments often decide the game because a single forcing move can turn a balanced position into a decisive advantage.
