world cup and game theory

Always nice to see a bit of game theory make it a little closer to something people actually read:

Game theory, applied to the problem of penalties, says that if the striker and the keeper are behaving optimally, neither will have a predictable strategy. The striker might favor his stronger side, of course, but that does not mean that there will be a pattern to the bias.The striker might shoot to the right two times out of three, but we cannot then conclude that it will have to be to the left next time.
