I mean, knee-on-belly with x2 wrist-control would allow you to do WHATEVER you wanted to a person in a fight to the death, its easy/natural to acheive, and they have *no options* to gouge your eyes or break your fingers. They could spit at you while you bitch-slap them to death, but no real damage. . . and you could always slip to full-mount- unless you're going to argue that's not BJJ-based. Also, head-butts. I think you and many others on here actually believe someone trying to snap your fingers or low-blow you is going to waver someone who'd mid-adrenaline fighting to the death. BJJ/Wrestling would still be the most effective forms, assuming you have any kind of (even sloppy) ground offense, like gnp, chokes, head-butts, etc.,
Also, real people in real street-fights/fights to the death get choked out all the time. Both wrestling and JJ's ability to easily nullify an opponent would be worth their weight in gold.
