How do I spot a tactical refutation in the middlegame?

What is a pin in classical chess?

The key idea is to use a check to drag the queen onto a vulnerable square, then exploit the resulting alignment and piece activity to win material. It is a classic example of converting initiative into a decisive advantage.
