A grandmaster needs to retain thousands of games in his head, for games are to him what the words of their mother tongue are to ordinary people, or notes or scores to musicians.

Donald Trump envies anyone who can do things he can't.

The Russian Dept of Tourism has declared Ukraine its most dangerous destination. Many Russian tourists have disappeared there.

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.

I would say that when you go to the very, very top, it's an ability to come up with new ideas, with something new, to make the difference. Every world champion, every player who was traversing this universe, managed to bring something new to the game. This ability to always find some unconventional ways. That makes the final difference.
