King's Indian Defense Fianchetto Variation Puzzle (Rated 978): Win Material — Tactical Refutation

This middlegame puzzle is about spotting a tactical refutation when the opponent’s queen and knight become overextended. White can use the active queen and knight coordination to force a favorable simplification and win material. The key idea is that a seemingly strong black piece on e4 is vulnerable because it is tied to tactical pressure on the queen and the surrounding pieces. In classical chess, these moments often decide the game by converting activity into a concrete material edge.
