I started betting on the first half of basketball and football games and it has become a nightmare for me. Only advice I can give anyone is not to do it. I won lots of money on the full games. Today I had the Bengals under 21.5 for the first half. The 49ers got a lucky fluke touchdown with 9 seconds left in the half. THat cost my parlay that I had with Saint Louis in college basketball. This was not the first time that I should have been going under on the entire game. I got greedy and want to cash in at the half time of the game. THis was my downfall for the last 2 weeks. I also started chasing 2nd half of games which was also a major mistake. Lets not make this mistake on betting on the first half of games and not chasing 2nd halfs. It is too hard to predict what is going to happen in the first half of games.
