Queens Gambit Declined Vienna Variation Puzzle (Rated 1178): Exploit a Pin — Discovered Attack
This puzzle is a classic middlegame tactical refutation built around a pin, a discovered attack, and a forcing check. White’s queen and knight coordinate to overload Black’s king safety and queen placement, while the pinned pawn structure limits defensive resources. The key idea is that one active piece can force a response, opening a line for another attacker to win material. When a queen is trapped and the king is exposed, tactical precision often decides the game immediately.
