Neo Grunfeld Defense Fork Puzzle (Rated 1046): Win with a Fork — Decisive Material Gain

This middlegame puzzle is built around a forcing knight jump that creates a decisive tactical fork. White’s active pieces coordinate against the black king and loose kingside pieces, while the black bishop and knight are vulnerable to tactical pressure. The key idea is to use a check to drive the king into a worse square, then win material by striking a hanging piece. In practical classical chess, these are the moments where activity outweighs static structure.
