I don't see why this is a serious discussion. If I raise with deuces preflop, my opponent pushes all-in for a full buy-in, and shows me A-K, I still fold. I prefer to play poker in cash games, not flip coins.
Also, here's an interesting link about expected value:
http://plato.stanford.edu/entries/paradox-stpetersburg/
"The ‘expected value’ of the game is the sum of the expected payoffs of all the consequences. Since the expected payoff of each possible consequence is $1, and there are an infinite number of them, this sum is an infinite number of dollars. A rational gambler would enter a game iff the price of entry was less than the expected value. In the St. Petersburg game, any finite price of entry is smaller than the expected value of the game. Thus, the rational gambler would play no matter how large the finite entry price was. But it seems obvious that some prices are too high for a rational agent to pay to play."
