Here's another one-- in "Grand Game", what would you do if, having made it to $1000, you were given the choice of taking that and stopping or risking it against picking the last item that was under the target price (which, I believe, is the choice that is always given in that game)?
Me, I'd say, "Bob, I'm really not sure, as I've never played this game here before, much less any game, but I believe that I should stand and take the $1000 I already have, because any one of them could go either way. I don't want to risk $1000 against a 1/3 shot of winning $10,000 or a 2/3 shot of losing the $1000. If I stand, I have $1000, but if I risk and I am wrong, just like you said, I lose the $1000, but then again, there is a $10,000 prize to be won; it is still probably not worth the risk to me though."
