Learn How to Exploit a Pin: Tactical Refutation
This puzzle comes from the King’s Indian Defense and shows how a single tactical shot can turn a middlegame into a decisive material gain. Black’s active pieces create a direct threat against the white king and also expose loose coordination in White’s camp. The key idea is to use a forcing move that checks the king while improving piece activity, then win material from the resulting pin and trapped-piece motifs. It’s a classic example of how initiative can outweigh static material.
