You are so well-trained in fighting from your horse that you are able to effectively flank a target while mounted – without the need for an ally on the target's opposite side.

Prerequisite(s): Mounted Combat, Ride 10 ranks and base attack bonus +6 or higher

Benefit: Whenever you are mounted, your horse is able to distract a medium-size or smaller opponent to such a degree that your target is considered flanked against any attacks which you or the mount make. Your horse may not move more than a 5 foot step during any round in which a target is virtually flanked in this way.

Normal: A target is normally only flanked when two or more opponents are on opposite sides of the target.
