Rule #1: If you are alone and a group of 2-3 guys approach to fight you and are not backing down, get the fuck out of there. Even if you are able to neutralize one of them, there will still be two more that will outnumber your limbs. That shit about one guy beating the crap out of 3 or more opponents works great in the movies. Unless you're a ridiculously talented heavyweight with deadly hands that have one-punch knockout power (i.e. Tyson in his prime), I would NOT take a chance. Even then, I would still advise against it.
That said, if it's just two guys fighting (with no outside influence or friends), I would happily take it to the ground and go for a choke. I would much rather roll on the ground and work on getting his arms, legs, ankles, shoulder or neck in trouble, than I would standing up and taking a chance at possibly getting bruised up or stitches.
It all depends on the situation..
"1"
i sparred with a bjj black belt mind you i have no submission knowledge other than
when you have you opponent laying on his back put your head in his chest
first round my fighting instinct didnt allow him to get any take downs
second round i couldnt keep him off and i gassed lol he was putting me in arm bars
and knee bars and they werent hurting because im double jointed but no one but me knew that
i was faking and screaming I WILL NEVER TAP... GRACIES AINT SHIT lol and the small crowd was shocked
at my "pain resistance".
third round began as he came in for the take down i put all my weight behind this punch and
cracked him in the sternum and he dropped like a sack of shit
moral of the story bjj aint shit in a street fight if you get taken to the ground scratch his eyes
grab his adams apple, bite him, grab his balls and squeeze very hard, elbow his face till he stops moving
or better yet do what mark coleman did and ground and pound his ass
if your in a fight 3 or more against 1 target the guy who started the fight take him to the ground and
you bite pieces of his flesh and choke that bitch untill he starts screaming and instead of his mates stomping you they will try to
break the fight up
