Stan ( Goose ) McDowell, ( Mizerak Sr.'s partner for 30 years or more ), told me once "Never bet on another guy's shot." What he meant was, if some guy tells you "I can make *this* shot..." ( which of course seems *impossible* ) "Gimme 50 shots at it and you can bet it up." then, in all probability, the guy CAN make that "impossible" shot, or he wouldn't be asking you to bet on it. So, by extension, if a good player offers you a game that seems he *can't win* at? As the old saying goes ( and, according to Stan, literally ), "Don't bet on it."
Give them what they want,not what they need.
