IMPROVED PIN [GENERAL]
Prerequisites: Dex 13, Improved Unarmed Strike, Improved Grapple
Benefit: You can use advanced grappling techniques to pin an opponent more effectively. Once you get an opponent in a pin, you are at +4 to all Grapple checks against that opponent.
In addition, while you have an opponent pinned you may make an opposed grapple check instead of a Strength check to trip the opponent. If the opponent is prone while pinned, you may not move the grapple.
Normal: Without this feat, there are no modifiers to Grapple checks to maintain a pin, and you may not render the opponent prone with an opposed Grapple check.
Special: A fighter may select Improved Pin as one of his fighter bonus feats.
A monk may select Improved Pin as a bonus feat at 2nd level, but only if she meets the prerequisites.
