New guy question

[The Truth]

I am new to this sports betting thing.

I would like to know something about the books.

Is the goal of Las Vegas Sports consultants to get 50% of all money on each side of given game? Or do they try to use their superior knowledge of the teams and their knowledge of public opinion to make the house more than the vig.

In other words, will they set the line at +5 when they know that the true line is probably around +12 simply because they know that more people will bet the other way, and they will make the house more money?


My opinion is that they try to get 50% on each side, however I have been told by sports guys that I know that this isnt the case.

Is this similar to "party is rigged" theories?


thanks alot
