Double knee backbreaker

 is a type of Backbreaker.

Description
This move was innovated by independent wrestler Chi Chi Cruz, who calls it the Cruz Control, and is also referred to as a Lung Blower. This backbreaker involves an attacking wrestler going behind an opponent and putting both of their hands round an opponent's head for a rear chin lock or on both of the opponent's shoulders while jumping up to place both his/her knees against the opponent's back; both wrestlers then fall backward to the ground, forcing the wrestler's knees to push up into the back of the opponent. Carlito of the WWE performs a version of this which he calls the Back Cracker or more recently the Back Stabber.
