[David Sklansky]

Goodness. What is wrong with everybody? The question was simply how should you change your strategy in a five game match when you have to win one game compared, to a one game match where you have to win one game.

And the answer is that unless your opponent changes his strategy, the strategy that works best for one game works best for all five. I don't care if its poker, chess or tiddliwinks. If you insist on math, you simply need to minimize the other guys one game chances, taken to the fifth power. x to the fifth gets smaller as x gets smaller. Duh.
