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

Dictatorships sometimes fall unexpectedly and quickly. And [Vladimir] Putin knows that for him, the loss of power doesn't mean a comfortable retirement, but something completely different.

A machine helps us to annihilate our weaknesses. We don't have a steady hand. We can lose all vigilance. We can be distracted by something that is not that relevant. But we have intuition. We can feel certain things. And with a machine you can check whether it's right or wrong. That's why by bringing the two together, you create a very, very powerful combination.

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.

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.

We see threats to liberal democracy coming from lots of directions. We have to create something new, a common response, because in so many places - the UK, France, Germany - ultranationalists and the far left threaten the free market and liberal democracy.

Quite frankly, I have to admit that with regard to the enormous financial assets and funds of Russian leaders in Western banks and on stock markets, the chances for the West to exert influence on Russia are quite low. I doubt that Western leaders are willing to exert pressure. I would not exclude an intervention in case of a crisis.
