Black To Move Puzzle (Rated 1396): Win Material — Tactical Refutation
This middlegame puzzle is all about spotting a tactical refutation when the opponent’s king safety is compromised and key pieces are loose. White’s queen activity creates pressure, but Black has a stronger concrete shot: the queen can invade for a direct material win while keeping the white king under control. The position rewards calculation over general plans, because the best move sequence converts activity into a decisive material edge and leaves White unable to keep everything defended.
