Vegas uses 55 to 60 cents on average to move a line 1/2 win up or down. Comparison shopping can get you out at 40 cents.
Never compromise by letting a tie become a loss.
If you like over on a play and the #'s are 7 -150 or 7 1/2 at =, do the 7. If the #'s are 7.5 and 8, I do the 8 unless I get a good price on 7.5.
The reverse happens on unders (use under 8, not 7.5, but can do under 7 vs 7.5)
ROCK THE BOOK!
GOOD LUCK!
