Learn How to Exploit a Pin: Decisive Material Gain
This puzzle comes from the Catalan Opening and shows how a pin can turn into a decisive material gain. White’s queen is exposed on the c-file, and Black’s rook activity creates a tactical net around the king and queen. The key idea is that one piece can be overloaded, so a forcing move can win material by attacking multiple targets at once. In classical chess, these short combinations often decide the middlegame before any endgame begins.
