The international repercussions were shattering to some extent - there is no intention to repeat operations of such kind in the future.[Viktor] Yanukovych's electoral victory clearly demonstrated that there are no pro-Russian politicians in the Ukraine, just Ukrainian politicians.

Enormous self-belief, intuition, the ability to take a risk at a critical moment and go in for a very dangerous play with counter-chances for the opponent - it is precisely these qualities that distinguish great players.

When [Vladimir] Putin, a former lieutenant-colonel in the KGB, became Russia's president on December 31, 1999 - eight years after the failed coup attempt against (then Soviet leader Mikhail) Gorbachev, and eight years after the people had torn down the statue of Felix Dzerzhinsky, the hated founder of the KGB, in Moscow - it was admittedly a shock. Nevertheless, I decided to give Putin a chance. He seemed dynamic and capable of learning. But I had to bury my hopes after just a few months. He proved to be an autocrat - and, because the West let him do as he pleased, he became a dictator.

Chess continues to advance over time, so the players of the future will inevitably surpass me in the quality of their play, assuming the rules and regulations allow them to play serious chess. But it will likely be a long time before anyone spends 20 consecutive years as number, one as I did.

Russian Parliament today is a bunch of puppets that just fall in with the instructions from Kremlin.

Ultimately, what separates a winner from a loser at the grandmaster level is the willingness to do the unthinkable. A brilliant strategy is, certainly, a matter of intelligence, but intelligence without audaciousness is not enough. Given the opportunity, I must have the guts to explode the game, to upend my opponent's thinking and, in so doing, unnerve him. So it is in business: One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.

I may play some exhibition games so I don't want to quit the game of chess completely. I just decided and it's a firm decision not to play competitive chess anymore.
