Learn How to Use a Pin: Decisive Material Gain
This middlegame puzzle comes from the Pirc Defense and shows how a well-timed pin can turn a normal-looking position into a decisive material win. White’s pieces are active, but Black has a tactical resource that targets the queen and king alignment. The key idea is that a pinned piece often cannot move because doing so would expose something more valuable. In classical chess, spotting these hidden relationships is often more important than counting material alone.
