Incidentally, Richard Garfield, designer of Magic, once wrote on the topic of luck in games. He said that there is, in fact, luck in chess, because we cannot predict the outcome with certainty. He went on to explain that if he sat down to play chess against Kasparov or some other world-class chess champion, he'd expect to lose, but there's still a possibility (however small) that he could happen to stumble upon a superior line of play, perhaps without even realizing it, and end up winning.
