I have been lucky betting 2nd 1/2 lines the last 2 weeks. I have no formula, I watch a first half, get a feel for how the teams are playing and if the books have what I think is the wrong number or in some cases the wrong favorite I bet it. Today when I logged on my account there was a note for me to call Customer Service. I was told that I have to play more than 2nd halfs or they really dont want my business. They even implied that only PROS bet 2nd halves and not the game. What do the posters here think about this?
