Obviously you didn't read what the blood choke was.
I'd go with the blood choke, preferably the rear naked choke. I've used it in almost every fight I've ever been in and it's good for incapacitating an opponent. I like to step in and grab their waist while using a leg sweep and pushing off with my other leg to throw them off balance. Then you want to be behind them and wrap your arm around their neck so that your elbow is at their adams apple and your bicep is on the carotid artery. Now wrap your legs around their torso so that your body is scrunched up a little. Now your going to stretch your body out while simultaneously flexing your bicep and pulling on the arm that is around the victims attackers throat at the place where your hand is locked onto your wrist. That's how I did it anyways.
