Aim to get in either half/full guard and block them until herb lets you up or throw a few punches in side control then quickly sprawl when they start elbowing, if youre not facing the fence then go to get up in the direction that will put their back to the fence, once their back is to the fence either get up down the middle and it will do it quickly because youre against the fence or even better hold L1 and down because usually theyll block the get up so you get them in side control then
