My bookie allows me to bet every over/under at -110. As you know, many games will have over/under lines sitting at -130 / +110. I'm not a mathematics guy but I figured in the long run I should do well if I only bet the games that are at -125 or higher since I'm getting a good price at -110 when the real line is -125 or higher. I would love to hear from the experts on how to take advantage of this.
