If you just hold on your opponent's ankle and keep running forward, your opponent cannot do any back flip to escape. I find that ankle hold can easily turn into a foot twist lock in the ground game if you don't release it.I used to use it in wrestling where no one throws kicks. It’s quite effective. I’ve seen a guy do a cartwheel kinda somersault kinda thing to get out of it once. Better way to describe it, he did what would look like a jumping crescent kick with his planted foot while the other guy was lifting his leg, and landed on his hands, then rolled out before his opponent could recover.
Only saw that one once, and it was beautiful. Never saw it again. And I couldn’t pull that off if I tried.
