Queens Gambit Accepted Alekhine Defense Puzzle (Rated 1426): Win Material — Tactical Refutation
This middlegame puzzle comes from the Queen's Gambit Accepted and shows a classic tactical refutation based on piece activity and loose coordination. White’s knight jump creates immediate pressure on the center and exposes a major tactical flaw: Black’s queen becomes vulnerable to a forcing sequence. The key idea is that active pieces can outweigh raw material when the opponent’s queen and bishop are both tactically overloaded. In classical chess, these moments often decide the game with a decisive material gain rather than a direct attack on the king.
