Barack Obama took over after Vladimir Putin's first aggression, in Georgia. In 2009, he did the reset policy because they had these stupid ideas about former president Dmitry Medvedev. They thought he would be the leader, not Putin. Everyone played this game with Medvedev as their bet, Berlin, Paris, London, the idea of smoothly transferring to something more acceptable. It was always a charade, a Putin project to solidify his power and come back after four years of nominal occupation of the office by Medvedev.

Boris Nemtsov and I began to argue after Putin's return to the presidency in 2012. In my opinion, there was no longer a realistic chance to achieve regime change through peaceful political means, or real elections. Boris, on the other hand, never lost this hope. He felt that my assessment was premature and said: "You have to live a long time to see changes in Russia." He was deprived of that opportunity.

For young players, their minds are not overloaded. I am 54 with four kids and I do many other things. Even if I stopped everything else, spent months working just on chess, for a long match against most of the top players, a classical match, six hours, say, I don't stand a chance. I have a better chance in shorter matches. Rapid is 25 minutes, or blitz events where you have five minutes to make a move, or bullet games, where it is one minute. For blitz, five-minutes chess, I would be top ten, top five. But longer games, no chance.

Do as little as necessary to appear to be doing something without actually committing to a cause or course of action.

I am between the Tories and the Lib Dems. I am fiscally conservative. I'm for strong foreign policy, but socially very liberal. I am not religious. That makes me feel uncomfortable with American Republicans. I don't feel at home anywhere, really. Labour under Tony Blair was not something I would associate myself with, but I didn't have a big problem with it. I have to make a choice between fiscal and the role of the state and social freedom.

Chess is not dominoes

Ultimately, what separates a Winner from a Loser at the Grandmaster level is the Willingness to do the Unthinkable.
