Pinning combination

In addition to square clearance, there is also such a thing as line clearance. With 'line cleareance' we do not clear a square, but rather a line (file, rank or diagonal). Clearing is particularly strong when it comes with tempo . Example 1 shows how we can combine a preparatory clearance move with a pin.

What do you have to do?

Clear a line (file, rank or diagonal) with tempo and then win material by creating a pin.
