Queens Gambit Declined Albin Countergambit Beginner Puzzle (Rated 1262): Win Material — Queen Pin Tactic

This middlegame puzzle comes from the Queen's Gambit Declined, where a pinned knight and an exposed queen create a tactical opening. Black’s bishop pressure on the kingside and the queen alignment on the d-file combine to force a simplification that leaves White unable to keep material balance. The key idea is not a mating attack, but a forcing sequence that wins the queen and converts the position into a clearly favorable endgame for Black.
