Bird Opening Defensive Move Puzzle (Rated 1385): Win Material — Tactical Refutation

This middlegame puzzle is about recognizing a forcing tactical refutation when an active enemy queen and knight overreach into your position. White has a clear material edge, but the key is not to play passively: the position contains a direct answer that wins back the initiative by exploiting an undefended piece and the exposed queen. In classical chess, these moments reward accurate calculation, because one strong tactical sequence can convert a small advantage into a decisive one.
