Blumenfeld Countergambit Other Variations Puzzle (Rated 1192): Exploit Discovered Attack — Winning Combination

This middlegame puzzle is a classic example of a discovered attack turning a stable-looking position into a decisive material win. White’s advanced pieces and active queen create pressure, but the key tactical idea is to use a forcing check that opens lines for the queen. Once the defender is dragged away, the follow-up wins material immediately. The position rewards calculation, because the tactical sequence also exposes a trapped queen and a vulnerable king-side structure.
