Learn How to Win Material: Tactical Refutation
This puzzle comes from the Queen's Gambit Declined, Three Knights Variation and shows a classic middlegame tactical refutation. White has active pieces and a lead in development, but one central piece is overextended and can be targeted by a forcing sequence. The key idea is to look for a move that creates a direct threat against multiple pieces at once, especially when a queen, rook, or pawn can attack a defended knight or bishop. When the opponent’s last move leaves a piece loose, tactics often decide the game immediately.
