Learn How to Win the Queen: Long Pin Tactic
This puzzle shows a classic long pin idea in the Petrov's Defense, where a seemingly active queen becomes vulnerable to tactical pressure. White’s queen is overextended in the middlegame, and Black can use a bishop to create a pin that also doubles as a skewer. The key point is that the pinned piece cannot move freely because doing so would expose a more valuable target behind it, turning activity into a decisive material gain.
