Earlier in my career, I never thought of boxing as a chess game, but I confirm that they are, in fact, very similar. You can plan your fights and strategy just like you would in chess.

After Chernobyl, thousands and thousands of people, if not millions, were given a death penalty and had to pay the price, our father among them.

Mental strength is really important because you either win or lose in your mind.

And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

I think a fight with David Haye, even if he is not American, is going to give positive vibes about the heavyweight division for the American fans and fans worldwide.

I think we have tremendous media covering the sport of boxing, even if boxing is a little bit lost in popularity with MMA sports.

I swim a lot. I train very hard at things that mimic boxing. I have to do mostly sport-specific training, such as lots of sparring.

I know he's retired, but I'm a big fan of Shaquille O'Neal, his game and his personality. I have a pair of his shoes in my office. You see the size of his shoe and think, 'This is not real, this couldn't belong to a human being.' But he is human!
