Michael Konik wrote in "Smart Money", that Billy Walters would have him bet a basketball line at 11, but not touch it if it was 11 1/2. I am curious how much the half point is worth? For example, if a pro says the line should be 11, then if the line is 11, you would assume a 50% chance of winning. Would 11 1/2 then be worth 52%, and 12, 54%? I am curious how you guys analyze this.
