Tarrasch's 'dogmas' are not eternal truisms, but merely instructional material presented in an accessible and witty form, those necessary rudiments from which one can begin to grasp the secrets of chess.

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.

I don't really like discussions about a supposed Russian national character.

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.

Constructs like race will decline in relevance in a roboticized world. That how well one human subset or community - a race, a nationality, a religion - is doing will be secondary to how well humanity in general is doing in face of the robot revolution.

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.

From Ukraine to Syria, he [Vladimir Putin] is behaving like the world's new general and celebrating victories, while the American president sits on the sidelines and Europe sleeps. The West's behavior toward Putin is political and moral capitulation.
