Occasionally, when I've passed someone's guard, the defender will take a death grip on one of my pant legs with his near-side arm and try to drag me back into half guard or just stall out with a stiff arm. Usually, they'll grip the bottom leg at the knee, so I'm stuck using my bottom arm to block the reguard, which limits my options for transitions. So the position I end up in is like this (sorry no photo): I have the crossface and his near side leg wrapped up, I'm sprawled out, driving into him. He has the grip on my bottom knee with his near-side arm. Does anyone have any options/ideas as far as what to do in this situation? With their arm fully extended like that, it would seem I could try to attack it somehow... Any ideas would be appreciated. Thanks.
