Learn How to Win Material: Advanced Pawn Fork
This middlegame puzzle comes from the Queen's Gambit Declined and shows how an advanced pawn can create a tactical refutation. The key idea is that a passed pawn on the third rank can become more dangerous than a piece if it attacks multiple targets at once. Here, the position is built around a fork and a forcing sequence that wins material by exploiting loose pieces and an exposed king. In classical chess, these motifs often decide the game quickly.
