I started playing chess when I was five years old. I learned the moves from my mother, then worked with my father - and later trainers. My style became very technical. I sacrificed a lot of things. I was always hunting for the king, for the mate. I'd forget about my other pieces.

I don't have enough information, and enough courage, to come up with a definite version of events. And I think it is too dangerous for me to do so.

I wouldn't place much stock in numbers. I don't believe that they reflect Putin's true popularity. Just think about how the pollsters proceed. They call people and they ask them questions on the street. In today's Russia, it takes a lot of courage to tell a stranger something critical about the head of the Kremlin. And yet more than 20 percent do so nonetheless.

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.

The regime is in trouble economically and can no longer offer anything to its citizens. That's why [Vladimir] Putin has to pursue an aggressive foreign policy, so he can serve his people the fairy tale of Russian pride and regaining its strength as a major power.

If people are being left behind, impoverished economically or even culturally, they will always be easily targeted by demagogues of any stripe, exploiting their hate and fear and making impossible promises. That impoverishment is more likely if we fight a doomed battle against automation and new technology, when what those people need most is the ambitious new tech that is the only proven way to create sustainable industries and jobs.

Like Dvoretsky, I think that (all other things being equal), the analytical method of studying chess must give you a colossal advantage over the chess pragmatist, and that there can be no certainty in chess without analysis. I personally acquired these views from my sessions with Mikhail Botvinnik, and they laid the foundations of my chess-playing life.
