Learn How to Win with a Pin: Chess Endgame Tactics
This puzzle is a classic example of how a pin can decide a chess endgame or simplified middlegame. One piece is forced to stay on a line because moving it would expose a more valuable target behind it, and that restriction creates a tactical win. The key idea is not just the pin itself, but the follow-up: once the defender is immobilized, the attacker can win material or force a decisive exchange. In classical chess, these quiet tactical motifs often decide games between strong players.
