Parasyte - the maxim

[shinta|hikari]

You can, somewhat, by analyzing their movements and stance.

Luck will always be a factor in fights, but it is a minor one. Would you bet on a high schooler sucker punching an MMA champion and winning that fight? Yeah, it is possible, but it is astronomically improbable. The idea that "spontaneous ideas" and "luck" can reliably overcome training and experience is utterly absurd and is obviously an inexperienced (in fighting or martial arts) opinion.

EDIT:

To clarify, I'm simply saying that fighting or combat is not any different from any other activity. It is affected by luck, but honed by training. Natural skill plays a part, but meaningless in the face of practical experience. Those "spontaneous ideas" actually come from experience. Ideas cannot randomly pop out from nowhere. You cannot expect someone to realize that leaping into an armbar is a faster way of disabling someone's arm if they did not even know what an armbar and how to do it was in the first place.
