Arbs and Middles or both....

As I mentioned in the previous post, I am starting to get into sports betting a bit.............not what you usually think of sports betting, my main focus are props and other mathematical type bets.........one example is an Arb (short for Arbitrage), this is a position in which you make 2 bets, and between the two bets you secure a profit...here is an example from about a month ago.....Book A had this line Albert Pujols under 2.5 Hits, Runs, RBI +110, Book B had this line Albert Pujols over 2.5 Hits, Runs, RBI +110, in this example, you could bet both of these lines, in equal increments and guarantee a profit.

Here is an example of a middle.....Book A has Team X -2.5 +105, Book B has Team Y +3.5 -105, bet in proper increments this is a perfect middle in which you can not lose, but you can possibly win both bets if Team X wins by exactly 3 (which in the NFL happens roughly 9.5% of the time and in NCAAF happens around 9.0% of the time).

This weekend, I found a few prop arbs, that also included very tiny middles with them, like this one that I found for the Sunday night game, Book A - Hines Ward under 69.5 rec yds +120 & Book B - Hines Ward over 67.5 yds rec -115, bet in proper increments, this is roughly a 1% arbitrage opportunity...............but it also contains a tiny middle............if Hines Ward has 68 or 69 yds worth of receptions in tonights game, you would hit both sides. This type of bet has a guaranteed profit with the chance for a very big gain if you hit a very slim middle.

The next time you are searching your favorite online books be on the outlook for arbs that contain tiny middles to add additional EV to your gamblings.
