Re: playing a game

Read your opponent's mind and bid a tiny amount higher than him?
I don't think there can be a "universally optimal" strategy, because if there was then you and your opponent would both pick the same number and the game would be tied.


Why did the vector cross the road?
It wanted to be normal.
