Queens Indian Defense Fianchetto Traditional Puzzle (Rated 1498): Win Material — Tactical Refutation

This middlegame puzzle is a classic example of a tactical refutation based on loose pieces and king safety. Black can exploit the fact that White’s knight is overextended and that key defenders are tied down or undefended. The position rewards concrete calculation over general plans: once the first forcing move lands, White’s king is dragged into a sequence where material drops quickly. In classical chess, these are the moments where a small tactical detail decides the game.
