Opening Puzzle (Rated 1457): Spot a Tactic — QGA
This opening puzzle features a tactical refutation in the Queen's Gambit Accepted, Central Variation. Black has created serious pressure around the white king, but an advanced bishop becomes vulnerable and the queen's attack is not fully supported. The key idea is to challenge the invading piece immediately, turning Black's king-safety initiative into a decisive material gain. This is a classic opening lesson: active-looking threats can fail when a piece is left hanging or an overloaded defender is exposed.
