The stock market and the gridiron and the battlefield aren't as tidy as the chessboard, but in all of them, a single, simple rule holds true: make good decisions and you'll succeed; make bad ones and you'll fail.

Dictators are not strategists in the way I normally use that term. All the dictator cares about is survival. That means constantly worrying about the tactical response, "What do I do today, tonight, tomorrow morning, to stay alive?" Vladimir Putin doesn't care what happens a year or five years from now. He just cares about staying in the game. That is all he needs to survive.

The regime is in trouble economically and can no longer offer anything to its citizens. That's why [Vladimir] Putin has to pursue an aggressive foreign policy, so he can serve his people the fairy tale of Russian pride and regaining its strength as a major power.

If you wish to succeed, you must brave the risk of failure.

Few things are as psychologically brutal as chess.

My mother lives in Moscow, and I would like to visit her. Now she always has to travel to Finland or a Baltic country to meet me.

Somehow, AI is playing an important role of breaking up the ice of complacency. We have a comfortable life, we just don't want to take risks. AI is threatening too many comfortable jobs to make people think about taking risks again.
