Pin is part of Actions After a Grapple on B370 which says:
- You may only attempt a pin if your foe is on the ground
This caused some confusion where some thought it might apply to Crawling or Sitting opponents.
This was clarified in DF where it says they must by Lying.
In GURPS Martial Arts: Technical Grappling there is no longer a pin, instead it happens when control points reduce ST to zero.
