I have a problem when bigger guys get thier posture broken in my closed guard. At least one of my biceps gets controlled and the guy will tripod up and go for the log splitter (force the knee through the middle). Now when the higher belts go for it, the head is lower on my stomach and I feel like I can push the head off center and work an attack. I'm not particularly bothered by this. However, when the newer guys go for it, thier weight is much more directly over me in a bad posture. I feel like I should be able to exploit this is some way. Often times because they haven't worked my hips higher, they can't get the knee though and just sit there and crush me, crossface me or (my favorite) work a forearm across my throat. I'm fine with exploiting the position if I can push his elbow past my face (like when he goes for a forearm choke) but if that fails I usually just open my guard and use the butterfly hooks or put the feet on the hips to get his weight back. The only sweep I could see hitting from there is perhaps an elevator sweep if I get my hips out a bit. I've always been taught to keep your hips lower than your head and not put too much weight on your oppoent or you will get swept over. Well, people are blatently not following the warnings and yet I feel like I can't exploit the opening. What is worse is I feel like since the whitebelts have success with the Tripod Crush of Doom they continue to do it which is a bad habit to develop. It is my duty to sweep the Tripod crushers for thier own good! Just like it is my duty to armbar the Mount Chest Pushers to show an incorrect behaviour. Any help?
