So, to restate my question... How much of effective fighting is just pure instinct and how much of it is legitimate "ancient Chinese secret"?
There are some people whose attributes, attitude, and enviroment will get them experience in fighting. But "instinctive" fighters aren't necessarily good fighters compared to trained fighters. Mike Tyson was by every report an aggressive badass streetfighter when he started boxing training, would anybody bet on Mike Tyson without training versus Mike Tyson with training? I wouldn't.
