There are two situations in which I would fight 2/3 people at the same time. The first would be by choice, as in, sparring class when factors are controlled (for the most part) and I am training. We do not do this regularly, but it is something we do. The second would be if I was attacked by more than one person, and I suppose it is possible as I spend a lot of time walking/out on my own, although it has not happened yet and I do not expect it to. If that should happen to me, I would fight 2/3 people at the same time. My other option is to curl up in a ball and take it, and, I would never do that. Ever. Would I stand over two bodies at the end of the fight without a scratch? Hardly likely. Would I "win"? What is your definition of winning? Getting some technically brilliant hits in? Standing over the bodies? As I said before, for me it is getting away as fast as possible with as little damage as possible. I am a fairly lightweight small person, I can't use my body size or strength to my advantage, I have to use speed, technique and accuracy. And that is one of the reasons I train kung fu, to improve in these areas. It also depends on who attacks. I think it would be easier to fight 2/3 women of my height/weight range then 2/3 men who are 6 foot 200 lbs. It would be easier to fight someone with no martial arts experience. This is why I asked you to rephrase your question, because I see so many factors involved.
I watched the brawl in Turkey..that guy in the black jacket did a great job keeping people away from him while keeping his hands up. He was alert and on his toes - the other guys were mostly taking wild swings.
