Learn How to Win Material: Queen's Gambit Declined

White’s setup looks active, but Black’s pieces are coordinated around the center and king safety, so the key is to notice which defender is overloaded and which piece is vulnerable to a forcing capture. In classical chess, these short tactical refutations often decide the game immediately.
