Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Nimzo-Larsen Attack and revolves around a tactical refutation that wins material. The key idea is to notice when a central pawn is loose and a piece can be captured with tempo or with a forcing sequence. In positions like this, classical chess calculation matters more than long-term plans: one accurate tactical shot can overturn a small edge and leave the opponent’s king and pieces badly coordinated.
