Queen's Pawn Game Accelerated London System Puzzle (Rated 1280): Win a Queen — Hanging Piece Tactics
This middlegame puzzle is all about recognizing a hanging queen and converting it with forcing play. White’s pieces are active, the king is safe enough to calculate, and the opponent’s queen is exposed on a vulnerable square. The key idea is that tactical moves can win material immediately when the enemy queen is both attacked and poorly defended. Once the queen is taken, the follow-up uses check and coordination to keep the advantage and simplify into a winning position.
