Honestly I weigh a few factors...first I look at home court and the overall line. If the overall line for the full game is low, I usually go with the first half line for that home team only because its supposed to be a close game (according to the small point spread), and the home team usually comes out revved up in those situations. Now, if it is a point spread that is big, for full game, I usually go opposite and take the away team, with the idea that the home team will not be as pumped up early on. However, on that side though, I also weigh the other factors with a big spread such as stats for the home team etc.
