Boxing and chess are similar. It’s about the choice of means. Sometimes I need a pawn, a bishop or a knight to defeat my opponent. It’s about finding the best way. A good boxer has to be variable. He doesn’t just need to know how to punch. He must also know how to protect himself, how to defend, how to avoid the opponent’s punches. Only a complete fighter can become champion.

I am going to have one Klitschko for breakfast and one Klitschko for lunch.

[Kirk] Johnson throws some heavy punches and is a knockout fighter. This is what people want to see. They want to see a fight, they want to see punches and they want to see action.

In boxing, if you think you will lose... you're already halfway there.

I play chess about four hours a day in training camp. You have to decide what move to use, or what combination of moves. I think less when I box because the reaction time is a lot quicker, but some people call me the chess boxer because they say I think too much in the ring. I take my time and they don't see the action they want. Some boxers just go in there and just throw punches and hope to win.

It's a very interesting fight [Klitchko vs Tyson Fury] because this is the first time [Wladimir] Klitschko is fighting someone as big as him and with longer arms. He will have to be a little bit more aggressive, otherwise the younger guy will have more speed and more energy and I think that may be the difference.
