Learn How to Win with a Pin: Middlegame Tactics
This middlegame puzzle shows how a pin can turn a seemingly equal position into a winning attack. The key idea is that one defender is overloaded, so a tactical strike on the pinned line creates a direct threat against the king and the queen. In classical chess, these moments often decide the game because king safety matters more than material count. Look for pieces tied to the king, especially on open files and diagonals.
