I weigh 130 pounds, and I am constantly rolling with a guy weighing 190. He's a cop, so some how or another I end up in the awkward "knee on face" position, much like what they are trained to do. ^^like this, except with a gi. Now...I have a decent ammount of time to ponder what to do next, because it takes me a good few seconds to escape from this annoying position. Is there something I can do to "make pain" for him in the -knee on face- position. Its pissing me off that I'm trapped in this position intill I kill my face trying to get out of it, I look like I drag my head across carpet. Is there a submission, or a good escape from it? or is it one of those "just dont get in it" things?
