Pivotal Chop (3.5e Maneuver)

Capitalizing on your foe’s forward inertia, you swiftly plant one foot and spin away too quickly for him to adjust, dodging his attack and slipping behind him before unleashing a vicious chop to his exposed backside.

When attacked in melee, you may execute this counter to make a Sense Motive check. If the result of the check equals or exceeds your attacker’s attack roll, you dodge the attack and switch places with him. In addition, once you have moved in this fashion, you may immediately make a melee attack against against the foe who just attacked you against which they are both flat-footed and flanked.
