King's Indian Defense Fianchetto Variation Puzzle (Rated 971): Crush with a Fork — Decisive Material Gain

This middlegame puzzle is all about a crushing fork that wins material by forcing the king to respond while another valuable piece falls. White’s active knight creates a tactical refutation against Black’s loose coordination, with multiple targets already under pressure. The key idea is to notice when an enemy queen, rook, or bishop is overloaded and when a checking move can also attack a second piece. In classical chess, these short combinations often decide the game immediately.
