I am having trouble when someone is in my guard and they get in real tight on me. They put their elbows on the ground and their arms on my sides, head/body into my chest and legs up real tight on me. I don't know what to do from this position because I always attack with a foot in the hip pretty much. I can't get my knee under him to sweep, I can't really do anything until he changes his position. Any ideas on what I should be trying to do from this position?
