One thing (of many) to consider if you are working to cap games is to bet the lines early. Review them as soon as they are posted to find an edge. This only applies if your not chasing steam or applying some other method.
The lines listed as "Opening" aren't really the very first lines created. Market making books (
Pinny, Circa,
Bookmaker,...) give their lines to their clientele of
sharps who are allowed to bet on them (with limits) so that the books can get better information and make adjustments before posting them as "Opening Lines" for everyone else. But, those "Opening Lines" are as fresh as you or I will ever see.
There still can be an edge that has not been beaten out of the lines. But, as they age/move, the edges will disappear.Why? Because there are smarter people than you and I seeing the same information and will bet and move the lines.
There are hundreds of other things to consider on how to beat the CLV (closing line value) but getting in early is one of them. Of course you have to be on the correct side not matter what.
