Ever since I messed up my knees real bad (well, they had been messed up, but I took that to another level a few months ago) I've found myself doing little things differently. One thing is, that whenever I'm under side control, I almost always bridge/shrimp and recompose guard something like this: That is, I never bring my bottom knee through any more. I sneak my top knee in just enough to catch their hip bone, and then I stretch out and regain guard. Unlike the picture above, my bottom leg would not be all the way through initially--it's the top leg that first gets between me and my opponent. Any thoughts on the merits or demerits of this technique?
