Closed Guard

A true closed guard is a position where you are laying on your back or side and both of your legs are wrapped around your opponents torso and your legs are locked together in some way. 

My method of categorizing guards as closed guards is a bit looser. It is a position where you are laying on your back or side and your opponent is positioned between your legs. The legs do not have to be locked. This looser definition allows me to include clamp guard as a type of closed guard.
