In chess you see everything. Every piece of information you need is available on the board, so what is being tested during a game is your ability to process all that information. In politics things are different: we never have all the information. People often compare politics to chess, but in fact politics is more like a game of cards, poker perhaps, in which winning means relying on guts, instincts and strength.
Which is why, in the terrible international game being played over Syria, Vladimir Putin is currently the master. Although — as I will explain — his winning streak may not last, at least for the time being he has outplayed all his opponents, largely because President Obama and other western leaders have left the game wide open for him.
