What is a Clearance Sacrifice?

A Clearance Sacrifice is a tactical motif where a piece (often with a sacrifice) moves to vacate a square or open a line (file, rank, or diagonal) for a more powerful piece to use.

How does it differ from a Discovered Attack?

While similar, the primary goal of Clearance is to 'make room' for another piece to enter the attack, whereas a Discovered Attack uses the moving piece to unleash a hidden threat from behind.
