RULE #3 - Watch 5Dimes
All books use .10 lines, except for Matchbook which is an exchange. However, in an exchange, you simply can't put down whatever bet you want. It has to be matched to be accepted.
There is one book (excluding Pinnacle's .08 lines) that feature lines less than .10 where your bet is instantly accepted. That's 5dimes, and that's only overnight.
If you're a professional bettor looking for the cheapest lines where you can put a large amount on one side and allow it to be accepted, you would go to 5Dimes, and you would bet overnight.
5Dimes changes overnight lines back to .10 around 9:00am EST. They frequently move the line in favor of one team as money has come in on this team overnight. Bet on that team.
Here's the PHI-SDG game (this would indicate a PHI bet)
06/03 12:20AM: +106 / -111
06/03 07:56AM: +100 / -110
Here's the CLE-MIN game (this would indicate a CLE bet)
06/02 11:53PM: -107 / +102
06/03 08:47AM: -114 / +104
Make sure the line move is significant. When the line moves 3 points in one team's favor, and 2 points in the other team's favor is not significant.
