So I've run into something lately that's made me wonder. When it comes to side control escapes, I have no problem getting out from under whites and blue belts (unless they have very strong wrestling backgrounds or a significant size/strength advantage) even then I can still usually get out from under them. But with my instructor, who is a very experienced purple belt I just can't get out from under him. Its not like I don't know what to do, and essentially the same side control escapes you use against a white belt you'd use against a purple, but the guy just shuts me down. I have about 20-30lbs on him and I'm an experienced blue (many think ready to make the jump to purple) but frankly its embarrassing just getting owned from the top like that. Most people I roll with (the majority really) can't pass my guard so working side control hardly ever comes up, but with my instructor I just get tooled if he ever manages to pass my guard. Thoughts? Advice?
