Most warriors have a hard time deciding between hitting once hard, or hitting twice quickly. This maneuver makes that choice irrelevant. By kicking your foe just above their center of mass with just the right timing, you can force them to shudder back and forth, causing them to effectively lean into your attack, increasing the effect! Furthermore, targets hard on the outside but soft on the inside (such as armoured foes) are battered against the inside of their own defenses.
