Learn How to Win Material: Tactical Refutation
This puzzle comes from the Queen's Gambit Declined and shows how a seemingly active piece can be punished when it is overextended. White’s position is built around activity and central control, but Black’s last move creates a tactical weakness that can be exploited immediately. The key idea is to notice hanging pieces, pins, and the value of forcing moves. In classical chess, a small tactical detail can outweigh the static material balance and turn the middlegame sharply in your favor.
