I can tell you that when it is a real fight, there are not much fighting capacity differences between two men who can be considered as peers.
Boxing needs to be watched as psychology. You can predict the winner very early based upon the results of the psychology dominance that takes place. Istanbuller is right in this regard. You can not totally disregard natural reflexes and training, but it is secondary to the psychology of the moment.
For example, you throw a left jab at your opponent just to feel him out. Instead, you get a solid connection and he stumbles back 3 feet. You have not hurt him physically, but you now have the dominant psychological position. On the other hand, you throw a knock out punch and the balance is all wrong and you end up giving him a light tap on the jaw. The psychology is all against you now. You have instilled fear of your own abilities.
I dream of the United Citystates of Earth, where each Citystate has a standardized border such as one whole degree of Latitude by one whole degree of Longitude.
