It was not about losing my mental power; it's about not feeling good about my contribution to the game.

A very strong player can manage and can just know how to manage a thousand positions. I get it; it's a very arbitrary number. So then you have the world champion who could do more. But, again, any increase in numbers creates, sort of, a new level of playing. And then you go to the very top, and the difference is so minimal, but it does exist. So even a few players who never became world champion, like Vassily Ivanchuk, for instance, I think they belong to the same category.

It is rather difficult to envisage a scenario that could change the domestic situation in the countries of the South Caucasus without solving the problems constantly hindering normal cooperation in the region.

The sanctions and travel restrictions would have to be far more comprehensive to be truly painful for [Vladimir] Putin and his inner circle. And the new middle class should also feel the effects of what he is doing. For instance, we should ask those who wish to enter the EU whether they have visited illegally occupied Crimea in the last few months and, if the answer is "yes," deny them a visa.

Many people think they are too refined, or too rational, to entertain a real sense of wonder in themselves or in others. This is preposterous to me, since the natural world is full of endless wonders, both on Earth and especially in space, no matter how you think it was created.

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.

Dictators are not strategists in the way I normally use that term. All the dictator cares about is survival. That means constantly worrying about the tactical response, "What do I do today, tonight, tomorrow morning, to stay alive?" Vladimir Putin doesn't care what happens a year or five years from now. He just cares about staying in the game. That is all he needs to survive.
