Carlsen will be ridiculously difficult to play against. (on the 2013 World Championship match)

Each match I play is the most important one yet.

There are some aspects of work you need to keep working on and no matter what environment you are in. Continuous learning is very important. It's what I call 'competitive tension', which is about having a competition around.

Intuition in chess can be defined as the first move that comes to mind when you see a position.

Psychology plays a big part but I always say psychology will only be a differentiator when the players are of equal technical strength.

When I started out playing chess as a kid I thought I should be world champion. As a kid you have no idea what that means and you only sort of picture it. It is hard to imagine that I waited all those years and it happened in a late stage of my career.

I like to keep myself physically and mentally fit before any important match. I usually take a short nap just before the game and do not practice immediately before the tournament.
