Defensive Play Puzzle (Rated 1281): Defend — Tactical Refutation

This puzzle is a classic defensive test in the middlegame: one side has active pieces, but the position contains a tactical refutation that turns the tables. The key idea is to meet threats with a quiet, precise defensive move that improves piece coordination and exposes an overloaded enemy setup. Once the first resource is found, the opponent’s active queen and knight become targets, and the position collapses into a winning material sequence rather than a direct attack on the king.
