Learn How to Win With a Pin: Middlegame Tactics
This middlegame puzzle is built around a powerful pin that turns a seemingly active piece into a tactical liability. When a queen or rook is tied to the king’s safety, every capture, check, and skewer becomes more dangerous. The key idea is to notice when an attacked piece cannot move freely because doing so would expose a more valuable target behind it. In practical play, these positions often decide the game immediately.
