Queen's Gambit Declined Puzzle (Rated 967): Win Material — Tactical Refutation

This middlegame puzzle is about converting activity into a decisive material gain. White’s advanced knight and active bishop look dangerous, but the position also contains loose pieces and tactical targets around the queenside and kingside. In classical chess, the side with the initiative must calculate accurately because active pieces can become overextended. Here, Black’s defensive resources are limited, so a forcing sequence can remove key defenders and leave White’s position collapsing into a simple material win.
