Learn How to Win with a Pin: Endgame Tactics
This chess endgame puzzle shows how a seemingly active piece can become a tactical liability when lines are already aligned. The key idea is a pin: one piece is tied to a more valuable target, so capturing it can win material or force a decisive simplification. In classical chess, these moments often arise from strong piece placement, loose coordination, and overloaded defenders. Even in a quiet position, a short tactical sequence can completely change the evaluation.
