Lots of folks have said all the right things about real street fights, and real fights in general. I'm not going to repeat them, other than to say that the best thing to bring to a street fight is a gun. The second best is a big friend, or 12.
But I'm going to guess that maybe we have someone a bit young and immature, who hasn't had the benefit of formal training, and is trying to ask a completely different question from what we're reading it as. So, I'm going to answer the two questions I see as maybe being his real goal. First one: what he really meant was "what's a good opening move in a sparring situation?" Lots of threads on that; to me, there are 3 ways to start while sparring. You can be defensive, and react to their first move (way #1). If you have to be offensive, you can use speed; quick jabs with feet or hands. That's number 2. Or you can be deceptive; throw a jab to sucker them for a kick or a different punch, for example. That's 3.
The other question I can see the OP as trying to ask is "what should I do if someone is about to fight me?" Lots of different threads on that, too. I'm not going to reiterate them, either. Sometimes, you do want to act before they act upon you. If so -- act quickly, decisively, and with intent. Or, you can wait, and respond to what they do. If so -- you REACT quickly, decisively, and with clear intent.
