Learn How to Win with a Pin: Chess Endgame Tactic
This puzzle shows how a pin can turn a balanced-looking middlegame into a winning endgame-style attack. The key idea is that one piece is forced to stay on a line because moving it would expose something more valuable behind it. When that defender is overloaded, the attacking side can create a direct threat against the king and win material at the same time. In practical play, these positions often look quiet until a forcing move opens the file and the pin becomes decisive.
