I don't see why people dont put their knee up straight through the guard. You don't get hit in the face because you pin the guys arms while you bring your knee through. And then when you have your knee all the way through, it's not like he can close a full guard around you again. You could sit there pretty stable and GNP the guy and he can't close his guard around you. Why doesnt anyone ever try this? I think I've only seen it once.
