We see threats to liberal democracy coming from lots of directions. We have to create something new, a common response, because in so many places - the UK, France, Germany - ultranationalists and the far left threaten the free market and liberal democracy.

When I was on an American show in 2015, I tried to talk about the threat Vladimir Putin posed to the free world. The interviewer said, "Wake me up when he takes over Poland." We heard something similar from years ago and we ended up with World War Two. Putin decided to skip Poland and went straight to Wisconsin. Putin is at war, a hybrid war, with the free world. His domestic propaganda is based entirely on a strong man challenging the free world. When the demonstrations around Russia began, the harsh response was because it was more important to show strength.

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.

I'm not in favour of a regulation-free world. I align myself with Teddy Roosevelt, who broke up the trusts. Regulation is necessary, but it should be in favour of the consumer, the citizen, and freedom.

I would not draw definitive conclusions from that. If we look at South and North Korea, it is pretty hard to believe that we're dealing with the same people. Half of the people are forced to live in a concentration camp; the other have created one of the most dynamic economies in the world.

I'm still number one and I just recently won a major tournament ahead of my toughest rivals so I think I had a few years ahead of me if I decided to stay.

I say we should praise Donald Trump for existing and for winning, because it has woken people up. For many years, I have been trying to say to Europeans, and especially to Americans, that Vladimir Putin is a problem for the world. And they have swatted me away. "It's your problem, we have our democracy." Suddenly, because of Trump, they are learning about separation of powers, independence of the judiciary and that Ronald Reagan was right when he said, «Freedom is never more than one generation away from extinction».
