Learn How to Win with a Pin: Tactical Refutation
This middlegame puzzle is a classic example of how a defensive move can turn into a tactical refutation. The key idea is to exploit a pin on the enemy queen and force a sequence where the opponent’s king safety collapses. Even though White appears active, the exposed king and loose coordination make the position fragile. In classical chess, these moments often decide the game immediately because one accurate forcing move can convert a small edge into a winning attack.
