Learn How to Exploit a Pin: Scotch Game Theory
This puzzle comes from the Scotch Game, where rapid development and central tension often create tactical chances in the middlegame. The key idea is an advantage-opening pin: one piece becomes tied to a more valuable target, limiting defense and creating a forcing sequence. In positions like this, king safety matters as much as material, because active pieces can turn a small lead into a decisive attack. Look for lines where a pin also improves coordination and opens hidden threats.
