3 points

When gravity is against you, maintaining contact is your friend. Two points are not enough, because when you lose one you’re basically hanging on by a thread. If you’ve ever tried to play guard without your hands, you know how difficult it is, and there is no guard without your legs. Look at the guards you play, and watch matches of people who play those guards, watch where they place their body. Grips, hooks, posts, and any other contact you see could be key to a successful guard.
