I've travelled around the world, I've lived in Germany, I've lived in the United States, I've visited many countries, I can question why such a good country, such huge potential, why we don't develop in the right way.

Chess is similar to boxing. You need to develop a strategy, and you need to think two or three steps ahead about what your opponent is doing. You have to be smart. But what’s the difference between chess and boxing? In chess, nobody is an expert, but everybody plays. In boxing everybody is an expert, but nobody fights.

I know that and I feel that.

Chess and boxing have a lot in common, as both sports rely on the right strategy.

There is one thing that I feel I still have to do and that is gain revenge over Lennox Lewis. If Lewis came back I would find the motivation to return to boxing and beat him.

I was actually very surprised, and I told myself wow, I want to fight this guy.

As a champion, I can't fight against weak fighters.
