Sicilian Defense Closed Fork Puzzle (Rated 869): Fork — Decisive Material Gain

This Sicilian Defense Closed middlegame features a classic tactical fork built on piece activity and king safety. White’s advanced pieces look active, but the position hides a forcing tactical shot that wins material by checking the king and attacking key defenders at the same time. The puzzle is a good example of how a single forcing move can turn a balanced-looking middlegame into a decisive advantage, especially when the enemy king has limited escape squares and important pieces are overloaded.
