The Soviet Union tried to sell a set of ideas, very left wing, and focus on so-called peace. Vladimir Putin doesn't care who helps him to push his agenda. He is equally comfortable with the politics of Nigel Farage and Corbyn in Britain, Le Pen and Jean-Luc Mélenchon in France. Whether far left or nationalist, he doesn't care, as long as they support chaos and destruction and the undermining of existing institutions.

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.

Ultimately, what separates a winner from a loser at the grandmaster level is the willingness to do the unthinkable. A brilliant strategy is, certainly, a matter of intelligence, but intelligence without audaciousness is not enough. Given the opportunity, I must have the guts to explode the game, to upend my opponent's thinking and, in so doing, unnerve him. So it is in business: One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.

At the northern border of Azerbaijan, Daghestan by no means contributes to the democratization of the Caucasus.

There are many ways of showing your protest and discontent without the actions of Kremlin.

Throughout my chess career I sought out new challenges, looking for things no one had done before.

All experiments that are related to the games when you have humans versus machines in the games - whether it's chess or "Go" or any other game - machines will prevail not because they can solve the game. Chess is mathematically unsolvable. But at the end of the day, the machine doesn't have to solve the game. The machine has to win the game. And to win the game, it just has to make fewer mistakes than humans. Which is not that difficult since humans are humans and vulnerable, and we don't have the same steady hand as the computer.
