You can take advantage of a distracted foe.

Benefit: When you attempt a combat maneuver check against a foe you are flanking, you can forgo the +2 bonus on your attack roll for flanking to instead have the combat maneuver not provoke an attack of opportunity. If you have a feat or ability that allows you to attempt the combat maneuver without provoking an attack of opportunity, you can instead increase the bonus on your attack roll for flanking to +4 for the combat maneuver check.

Special: This feat counts as having Dex 13, Int 13, Combat Expertise, and Improved Unarmed Strike for the purposes of meeting the prerequisites of the various improved combat maneuver feats, as well as feats that require those improved combat maneuver feats as prerequisites.
