Improved Grapple

Improved Grapple (Combat)
You are skilled at grappling opponents.
Prerequisite: Proficiency in unarmed strikes
Benefit: You do not provoke an attack of opportunity when performing a grapple combat maneuver. In addition, you receive a +2 bonus on checks made to grapple a foe. You also receive a +2 bonus to your Combat Maneuver Defense whenever an opponent tries to grapple you.

(BAB +6): You receive an additional +2 bonus on checks made to grapple a foe. Once you have grappled a creature, maintaining the grapple is a move action. This feat allows you to make two grapple checks each round (to move, harm, or pin your opponent), but you are not required to make two checks. You only need to succeed at one of these checks to maintain the grapple.
