English Opening Adorjan Defense Puzzle (Rated 1500): Pin and Win Material — Tactical Refutation

This middlegame puzzle is a classic example of tactical refutation built around a pin and a hanging piece. White’s active bishop creates pressure on the enemy queen, and the key idea is that the queen cannot simply move away without dropping material or allowing a decisive simplification. The position rewards accurate calculation: once the pinned piece is forced to capture, the follow-up wins material and leaves White with a clear advantage. It is a strong example of classical chess tactics in action.
