Zukertort Opening Discovered Attack Puzzle (Rated 1154): Exploit Discovered Attack — Winning Combination
This middlegame puzzle shows how a discovered attack can turn a seemingly active position into a decisive material win. Black’s central pawn thrust opens lines at exactly the right moment, creating a direct threat against the white queen while also forcing a response to the check on the king. The key idea is that one tactical blow can do two jobs at once: expose a hidden attacker and win a major piece. In classical chess, these forcing motifs often decide the game immediately.
