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.

In chess the rules are fixed and the outcome is unpredictable, whereas in Putin's Russia the rules are unpredictable and the outcome is fixed.

Losing can persuade you to change what doesn't need to be changed, and winning can convince you everything is fine even if you are on the brink of disaster.

It was an impressive achievement, of course, and a human achievement by the members of the IBM team, but Deep Blue was only intelligent the way your programmable alarm clock is intelligent. Not that losing to a $10 million alarm clock made me feel any better.

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.

Vladimir Putin mainly has friends in Europe among the extreme right, such as Marine Le Pen's Front National in France.

Excelling at chess has long been considered a symbol of more general intelligence. That is an incorrect assumption in my view, as pleasant as it might be.
