What would you do if you face your fighting opponent at first?

Everyone might have some experiences of fighting his friend or someone he does not know. Otherwise, everyone must have experience to see someone fight another. Let's suppose you are in that situation and you didn't know special fighting skills like usual, at first.

You must be standing watching your opponent and he must be watching you too. In real fighting, one of you has to attack the other any way. If you attack first, what would you do? Usually almost everyone punch at his opponent in his attack. Consider this case in order to investigate the best punching skill and the defending against it.

Let me notice two faults of common man's punching. First, comman man pulls back his fist a little bit unconsciously before punching like the first <picture 1> in almost cases. Second, he punches like swingning his whole arm like <picture 2>. Why? Both result from his intention to make powerful punch because he hates and fears his opponent in real case. He draw his fist back in order to make powerful punch, and since he intends to make use of body motion for the power of fist he come to turn his upper body swinging his arm, which results the curve orbit of his final fist motion. However, in spite of his hate and fear, these faults cause his attack to fail. You can often see scenes in a movie that someone defend his opponent's punch like <picture 3>. When you swing your arm ambiguously your opponent can block it with ease merely holding up his arm and he can be the hero in the movie in real.

Seeing this tells you that defending and counterattacking common man's punch is very easy. But, in real, it would not be so easy as can be imagined, the reason of which will be explained later.
