I am getting my butterfly guard passed by this high purple belt ALL the time.....he does the pass where he keeps his elbows down, head to one side, and does a head/handstand jumping over my legs to one side and ending on perfectly in side mount. I know its coming but he pinches my heels to my ass and basically gets his elbows to touch his knees so he is doing the pass perfectly and I can't stop him at all! I know you are going to say "Dont let him get that tight" but he is really good. SO is there anything I can do to stop him from doing this once he gets tight? Or what can I do to not let him get that tight? Thanks!
