Learn How to Pin: Crushing Middlegame Tactics
This puzzle is a classic middlegame example of a pin turning into a decisive tactical gain. The key idea is that one active bishop can create immediate pressure on the enemy queen and king at the same time, forcing a response that leaves a major piece vulnerable. In classical chess, these positions often arise when development is ahead and the opponent’s king safety is already compromised, so a single forcing move can collapse the position.
