So I've been reading a bit on sports betting and understand the basic concept, but one thing I cant seem to figure out is how some cappers can find out the ending score on a game before it starts. I tryed to average the overall points for each team playing but, I dont think thats correct. Also, I understand you can see a "wise guy" move from watching the lines but how do you know that the line has been purposely moved by the sportsbooks to make it look like a wise guy move? 
Thanks guys.
