Learn How to Win with a Pin: Tactical Advantage
This puzzle shows how a single pin can turn a promising position into a tactical collapse. In the middlegame, the key idea is to use a bishop to line up pressure on a defended piece so that moving it would expose something more valuable behind it. That kind of tactical advantage often appears when the king, queen, or rook is tied to a vulnerable square. Once the pin lands, the opponent’s pieces can become overloaded and short of useful squares.
