Qxd4 Puzzle (Rated 984): Pin — Material Gain
This Scandinavian Defense position illustrates how active pieces can turn a pin and overloaded defenders into a decisive material gain. White’s bishop on c7 creates pressure around the uncastled black king while also targeting a vulnerable knight. Black’s queen is active but exposed, and its multiple tactical responsibilities make the position unstable. The key idea is to use a forcing check to change the balance immediately, remove a defender, and leave the queen vulnerable to a follow-up capture.
