Caro Kann Defense Breyer Variation Puzzle (Rated 891): Win a Queen — Tactical Refutation

This middlegame puzzle is about recognizing a forcing tactical refutation when an enemy queen becomes overextended. White’s king is exposed in the center, but Black’s queen on d4 is the real target: it is active, yet vulnerable to capture because it is also tied to other loose pieces and weak squares. The key lesson is that a strong-looking attack can collapse instantly when the opponent can win the queen by force and simplify into a winning material edge.
