Modern Defense Standard Defense Fork Beginner Puzzle (Rated 991): Win a Fork — Decisive Material Gain

This middlegame puzzle is all about tactical refutation and exploiting a hanging piece. Black’s pieces are active around the white king, and the key idea is to use a forcing check to drag the king into an awkward square. Once the king is displaced, a knight fork wins material by attacking multiple targets at once. The position shows how a single tactical sequence can turn a large material deficit into a decisive advantage by coordinating checks, piece activity, and a trapped piece.
