If critics and competitors can't match your results, they will often denigrate the way you achieve them. Fast, intuitive types are called lazy. Dedicated burners of the midnight oil are called obsessed. And while it's obviously not a bad idea to hear and consider the opinions of others, you should be suspicious when these criticisms emerge right on the heels of success.

Dictatorships can exist with free markets - not that China is really a free market - especially in poor countries where the regime insists that it's a choice between food and liberty, a false choice. But increasing affluence will inevitably result in political pressure.

It's quite difficult for me to imagine my life without chess.

If you're already in a fight, you want the first blow to be the last and you had better be the one to throw it.

One lesson is to not to play desperately if your position is worse but still reasonable. Lashing out wildly in an inferior position usually only hastens defeat. Meanwhile, solid, stubborn defense can demoralize the attacker, make him lose confidence. When that happens, the tables can turn. Keep fighting, stay steady, keep morale high - and public protests are good for all of these things.

[Vladimir] Putin wants to keep [Bashar] Assad in power and expand his own military base in Syria, whatever the cost. I even believe he has an interest in more and more people fleeing the country. The flow of refugees improves his negotiating position toward the West, including the German chancellor.

The legend of the best player of chess has been destroyed.
