today, we learned 4 escape/submissions from a headlock on the ground. basically, just like this EXCEPT both arms are free,.. in this pic one arm is trapped in the legs (sorry, first photo I could find on google): each of them required either getting your upper leg over the person's head (which would lead into a sub), or hooking it inside the person's thigh (rolling over to mount, or getting into some sort of shoulder lock). when we actually live drilled them, i was able to pull them off fairly well on other white belts around my skill, but one of them has been wrestling for a number of years and i just couldn't get him. basically i could keep trynig to get on my side but i could never succeed in getting my legs near him, and eventually he'd quickly flip me into full mount. i also noticed that when I was the one holding him in the headlock, he'd often wrap his arms around my body instead of framing them in front of my head (like we were taught to do with the 4 moves today to push their head back). so... what are some options in this case? he's obviously been doing this in wrestling for a while, so what other ways can i get out of this headlock if he's not letting me get my legs near him?
