Learn How to Win Material: Tactical Refutation
This puzzle comes from the Nimzowitsch Defense and shows a classic middlegame tactical refutation. White can exploit a pin, a hanging piece, and a loose defender to win material and keep a decisive advantage. The key idea is that one active capture can force the opponent into an unfavorable sequence where a pinned piece cannot recapture freely. In classical chess, these short tactical wins often decide the game before any endgame is reached.
