I am not much on flashy martial arts techniques being used in fighting, as most of the time it is just ineffective and a waste of energy.
But, there are rare occasion where you can get lucky and come out looking like a boss, again it is usually just luck.
This is one of those rare occasions where the guy pulls off one of those moves that you normally only see in Kata, one steps, or demonstrations and connects with it catching his opponent off guard knocking him out.
Just goes to show that you really have to be on guard because you never know what your opponent might do.
