Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Queen's Gambit Declined, where piece activity and tactical awareness outweigh static structure. White has a strong kingside setup and active knight play, but the position contains loose pieces and a vulnerable queen-side cluster. Black can exploit the coordination problem by creating forcing exchanges and tactical pressure against the queen and knight. The key lesson is that a seemingly active attacking position can collapse if one piece is overloaded or left hanging.
