French Defense Queen's Knight Puzzle (Rated 884): Win Material — Tactical Refutation
This middlegame puzzle is a classic example of a tactical refutation in a position where one side has a decisive material edge. White’s active pieces and strong outpost create a forcing sequence that targets an undefended queen and exploits the alignment of the rooks on the e-file. The key idea is not a flashy attack on the king, but a clean conversion: win the exposed piece, force simplification, and leave the opponent with no compensation.
