Boris Nemtsov and I began to argue after Putin's return to the presidency in 2012. In my opinion, there was no longer a realistic chance to achieve regime change through peaceful political means, or real elections. Boris, on the other hand, never lost this hope. He felt that my assessment was premature and said: "You have to live a long time to see changes in Russia." He was deprived of that opportunity.

My opponent is Short and the match will be short.

In Syria, Vladimir pUTIN sees the chance to make millions of refugees and weaponise them. The US has to take a lead in defending the values of the free world.

One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.

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.

I've seen up close the benefits and drawbacks of kids working with super-strong chess programs in their training, and they definitely think differently than past generations thanks to this alien influence. While we are making our machines more intelligent, they are also changing how we think.

Putin is like Al Capone.
