[Vladimir] Putin spoke unabashedly about the importance of national sovereignty in Syria, a concept apparently near and dear to his heart, unless it comes to the sovereignty of Georgia, Ukraine or any other country in which he intervenes. Then he offered his cooperation, but without making any concrete concessions at all. And he didn't have to, either. He knows what he can rely on. He has assets that are more valuable than words: He has tanks in Ukraine, fighter jets in Syria - and Barack Obama in the White House.

I don't really like discussions about a supposed Russian national character.

Chess is a unique cognitive nexus, a place where art and science come together in the human mind and are then refined and improved by experience.

Thanks to the Polgars the adjective 'men's' before events and the 'affirmative action' women's titles such as Woman Grandmaster have become anachronisms.

Chess is an art and not a spectator sport.

Vladimir Putin has this animalistic instinct of all dictators: He smells weakness. To quote Winston Churchill's definition of appeasement: "An appeaser is one who feeds a crocodile, hoping it will eat him last."

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.
