Throughout my chess career I sought out new challenges, looking for things no one had done before.

The most hopeful approach to peace in Ukraine is the Minsk Agreement, which includes Moscow.

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.

If we look at statistical data, we see that Protestant countries in terms of economic development are more successful than those observing Catholicism.

I have some security that could protect me against provocations but of course there are more terrible actions that could not be stopped by any security.

Tactics involve calculations that can tax the human brain, but when you boil them down, they are actually the simplest part of chess and are almost trivial compared to strategy.

Donald Trump is a catalyst. People care now in a way they didn't. The American institutions were rusting; now they are being revitalised. Trump is a lightning rod. They are getting engaged and the American liberal media that spent too much time on PC issues can focus on Vladimir Putin and Recep Tayyip Erdogan.
