Learn How to Win Material: Pin Refutation
This puzzle comes from the Queen's Gambit Declined, Janowski Variation, and it shows a classic middlegame tactical refutation. White’s queen is active, but it becomes vulnerable because the bishop on b4 creates a powerful pin against the queen and king line. In positions like this, activity alone is not enough: one accurate defensive tactic can turn the tables and win material. The key idea is to recognize when a seemingly strong queen move is actually overloaded and tactically loose.
