Caro Kann Defense Hillbilly Attack Puzzle (Rated 1399): Refute a Fork — Win It

Black's last move created a classic middlegame fork: the knight attacked your queen and a pawn at the same time. Rather than retreating and conceding tempo, the winning idea is a tactical refutation — a forcing countercheck that also targets the forking piece. When the forking knight is undefended, this turns Black's aggressive move into a decisive material gain. The check brings the queen to an active square, presses Black's weakened kingside, and leaves the attacker as the piece that actually falls.
