This is the essential element that cannot be measured by any analysis or device, and I believe it's at the heart of success in all things: the power of intuition and the ability to harness and use it like a master.

It's not enough to be talented. It's not enough to work hard and to study late into the night. You must also become intimately aware of the methods you use to reach your decisions.

There is a good chance Donald Trump won't survive four years. Conflict of interest is the biggest danger for Trump. He is destroying one of the pillars of the free world. He is seeking to eliminate the very concept of conflict of interest. A lot of things in America were built on a code of honour. I am confident the damage done by ruling through family and friends will be made impossible by future regulation.

You cannot say, 'Go! Go! Rah! Rah! Good move!' People want some emotion. Chess is an art and not a spectator sport.

The only successor to President Putin is President Putin himself and we could of course dream about President Putin stepping down voluntarily and picking out successor which would be probably as bad as him.

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.

Dictatorships sometimes fall unexpectedly and quickly. And [Vladimir] Putin knows that for him, the loss of power doesn't mean a comfortable retirement, but something completely different.
