Queens Gambit Accepted Alekhine Defense Puzzle (Rated 1149): Win Material — Crushing Tactical Refutation

This puzzle is a classic middlegame tactical refutation where White turns active piece placement into a decisive material gain. The key idea is to exploit a pinned and overloaded defender while the opponent’s pieces are awkwardly coordinated. White’s knight jump creates a forcing check that drags the black queen into a vulnerable square, and the follow-up bishop move wins more material by attacking along a long diagonal. It is a strong example of how activity and space can outweigh equal material.
