Dictators are not strategists in the way I normally use that term. All the dictator cares about is survival. That means constantly worrying about the tactical response, "What do I do today, tonight, tomorrow morning, to stay alive?" Vladimir Putin doesn't care what happens a year or five years from now. He just cares about staying in the game. That is all he needs to survive.

All that now seems to stand between Nigel and the prospect of the world crown is the unfortunate fact that fate brought him into this world only two years after Kasparov.

Capablanca possessed an amazing ability to quickly see into a position and intuitively grasp its main features. His style, one of the purest, most crystal-clear in the entire history of chess, astonishes one with his logic.

This traditionally happens in Russia and in every other undemocratic country as well - the quest for a scapegoat won't be long, either. The easiest way to find a scapegoat is to ascribe that role to former governments.

Setbacks and losses are both inevitable and essential if you're going to improve and become a good, even great, competitor. The art is in avoiding catastrophic losses in the key battles.

The sanctions and travel restrictions would have to be far more comprehensive to be truly painful for [Vladimir] Putin and his inner circle. And the new middle class should also feel the effects of what he is doing. For instance, we should ask those who wish to enter the EU whether they have visited illegally occupied Crimea in the last few months and, if the answer is "yes," deny them a visa.

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.
