Fighting is easy to understand. You just hit the guy as hard as you can.
Fedor has no weakness. I have seen so many fights, and even the best fighters in the world have a flaw in their game but I have yet to find one in Fedor Emelianenko.
As long as you fight, you cannot lose... if you leave everything out there, it doesn't matter if you win or lose. To me you can never lose.
