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.

Attackers may sometimes regret bad moves, but it is much worse to forever regret an opportunity you allowed to pass you by.

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.

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.

Many Republicans who traditionally were for a positive role in the world, anti-Russian, now they want to defend their party and leader, and they don't care about real arguments. The paradox is the Democrats were so timid in criticising Vladimir Putin. Barack Obama appeased him and now they are criticising Putin's interference in American democracy. It is a strange reversal of the roles.

When considering the Islamic world, Turkey is the best example of a country where democracy irreversibly gained a foothold despite religious and cultural traditions still respected today. With some reservation, this can be said about Pakistan, too, where we can observe dynamic political processes going on [and] governments change as a result of elections. In my opinion, it is up to the ruling elite to initiate cardinal changes.

Many people think they are too refined, or too rational, to entertain a real sense of wonder in themselves or in others. This is preposterous to me, since the natural world is full of endless wonders, both on Earth and especially in space, no matter how you think it was created.
