Ah Yes...MATHPROF is right BUT did you read his caveat: over many occurances. The law of large numbers is not on your side, though. Although the words of Mathprof ring true, the problem is the 'over many occurances.' You are in a position to guarantee yourself profit. Maybe one way that you could take into account the Mathprof's suggestion is to use his approx 40% 60% breakdown and do this: Actually, I would have to think about this a bit longer, but it has to do with expected values. IN short HEDGE. THere absolutely is a mathematically optimum HEDGE amount, but it AINT not hedgin at all!!! Trust me on this. You should obviously hedge such that if Minny wins you receive far more than you would if Chi Sox wins because Minny is the odds on favorite! I would do the $500 play. $400 (chi sox win) to $1000 (minny wins) seems to me to be 'about' right, but I know there is an optimum amount given expected values of what you are receiving. (nothing against Mathprof, and I love his posts) tulsa
