Chess - it's a nonmainstream game. And the irony is that when you look at Hollywood, it kept using chess as the symbol of intelligence for its heroes, for its top characters, all the time. So it's from "Casablanca" to "Harry Potter." You always have chess as a very important element to demonstrate intelligence, while in normal life people think it's just a weird intelligence - like AI.

The biggest problem I see among people who want to excel in chess – and in business and in life in general – is not trusting their instincts enough.

Enormous self-belief, intuition, the ability to take a risk at a critical moment and go in for a very dangerous play with counter-chances for the opponent - it is precisely these qualities that distinguish great players.

I see my own style as being a symbiosis of the styles of Alekhine, Tal and Fischer.

Alexei Navalny, the opposition politician who has led anti-corruption protests, had a blog about a credit line to a company owned by Vladimir Putin's son-in-law, $1.75 billion from Russian state funds; this is one transaction. Putin controls more money directly and indirectly than any individual in human history.

Our skin, our borders, all seem petty compared to alien races and the scale of galaxies. Nobody in the Star Wars universe cares about white or black humans, it seems, and what meaning could physical appearance possibly have when there are sentient beings that look like lobsters or like Jabba the Hutt? Unfortunately, in the real world, such hopeful sentiments are regularly refuted by our stubborn insistence on always finding someone to discriminate against.

The stock market and the gridiron and the battlefield aren't as tidy as the chessboard, but in all of them, a single, simple rule holds true: make good decisions and you'll succeed; make bad ones and you'll fail.
