Queen's Gambit Declined Exchange Variation Puzzle (Rated 1163): Win Material — Discovered Attack

This middlegame puzzle is a classic example of a discovered attack combined with a forcing check. Black’s active pieces coordinate against White’s queen and king, creating immediate tactical pressure. The key idea is that one piece can move with tempo, uncovering a stronger line for another attacker. In positions like this, the side to move often wins material by forcing the opponent into a sequence where defense is impossible and the queen becomes overloaded.
