Queens Gambit Accepted Classical Defense Puzzle (Rated 1397): Win Material — Decisive Middlegame Tactics

This puzzle is a classic middlegame example of winning material through tactical pressure rather than a direct king attack. Black’s queen activity creates multiple threats at once: it attacks loose pieces, exploits a pin on the c-file, and targets a bishop that is not well defended. The key idea is to notice when one tactical shot forces a recapture and leaves another piece hanging. In practical classical chess, these positions often decide the game by converting activity into a large material gain.
