Learn How to Crush with a Fork: Pin Tactic
This middlegame puzzle shows how a forcing check can expose a loose king and overloaded defenders at the same time. The key idea is a crushing fork: one piece gives check while also threatening a major material win, and the follow-up keeps the opponent tied down by a pin. In positions like this, the side to move often has a clear tactical edge because the enemy king cannot safely ignore the threat, and the pinned piece cannot move freely to defend.
