FStep said:whats a good way to stop this/get out of it once its locked in but before the person pulls guard
Cardio said:1. Palm face in, grab his wrist or thin part of his forearm (like a one handed chinup) to take some pressure off your neck.
2. Now throw your far arm over his shoulder and as deep down his back and center as you can.
Now he can yank, crank and pull all day - now he has to lift your entire bodyweight and there is no pressure on you at all.
Actually this was taught to us at a seminar by BJJ RED BELT Carlson Gracie Sr.
