PLAYING POKER WITH KOREA
One of the meta-reasons America won the Cold War is that Russians play chess, while Americans play poker.
Chess demands great skill and intelligence, particularly at developing complex long-range strategies and anticipating your opponent's moves. But it bears little resemblance to life in the real world. It is completely static and open. Nothing is hidden. Poker is very different. You have to guess what your opponent has and the extent to which he is bluffing. In business, in politics, in life in general, the folks who know how to play poker will almost always fare better than those who know how to play chess.
