You even have an advantage over the bookies to help you. That’s the advantage of not having to bet. Bookies are expected to make markets on a whole host of sporting events, and honour those prices if someone tries to bet on them. You don’t have to do that. You can focus on the stuff that you can understand better, that you have good data on, that you have models that provide good odds estimates on. You can sit and wait for the times the bookies get it wrong, because among all the noise they do get it wrong sometimes. You wait, and you wait, and you wait as long as you need to wait. Then you bet. And you do so with the odds in your favour and vig eliminated as much as possible.

All gambling is mathematics, even games of chance. If you understand the math behind the game, you understand the game and can give yourself an advantage. For many games, like penny slots or poorly placed roulette bets, are so bad that smart bettors earn their advantage by avoiding them altogether. In sports betting, the math is more complicated. Depending on your favorite sport, you may need to think about things like bye weeks, underdogs, quarterback ratings, and injuries with the same fervor other connoisseurs reserve for fancy winces.
The sports books line is flawed if it does not attract the same action amount on both sides. From a smart handicapper’s point of view, the line is flawed when it does not compute to his predicted outcome of the game. A weaker team can actually become the favorite if public sentiment is with that team. When this happens the underdog presents a huge overlay for the seasoned handicapper tilting the odds in his favor. This is the contrarian principle and why many smart handicappers go against the general betting public.
