Learn How to Win Material: Tactical Refutation
This puzzle comes from a Queen's Gambit Declined middlegame where Black can turn piece activity into a decisive material gain. The key idea is to notice when a defended-looking piece is actually vulnerable because of alignment, loose coordination, and tactical pressure on the king side. In positions like this, a forcing capture can remove an important defender and leave White’s pieces overloaded. The result is not a mating attack, but a clean winning combination that shifts the evaluation sharply.
