    I wrote about this in July, 2001, at this URL:

    The problem is that for his paradox to work, the games have to be set
    up so that the payoff depends on your cash balance. No real games work
    that way, so the paradox is artificial. In my posting above I came up
    with a trivial example which demonstrates that.
