French Defense Queen's Knight Puzzle (Rated 1121): Win Material — Tactical Refutation

This middlegame puzzle is a clean example of a tactical refutation based on forcing exchanges and overloaded defense. White’s queen is tied to several important duties, while Black’s active queen can exploit the loose kingside and the vulnerable h-pawn. The key idea is to use a forcing check that drags the white queen into a position where it can no longer defend everything at once. After the dust settles, Black’s king can recapture and convert the advantage through simplification.
