Learn How to Use a Pin: Middlegame Tactics
This middlegame puzzle is built around a powerful pin and the pressure it creates on the king’s shelter. When a pinned pawn or piece cannot move, the defender becomes overloaded and tactical shots appear quickly. In positions like this, the best move often forces the king into a worse square and then wins material with a discovered or double attack. The key idea is to use forcing moves to keep the opponent tied down.
