I just got interested in horse racing(gambling). I've been hanging out at my sportsbook with a friend who is into it($100 each to show on 20 races). What is the best way to handicap races?? There are so many racetracks and so many races going on. My friend hangs out at the sportsbook from noon to 7:00. I'm married so I can't do that and learn. 
Thanks for the help ahead of time.
