I have played 7 2nd half lines tonight. It looks like I will go 1-6. The interesting point about it is that I bet the 2nd half on the teams that I liked before the game started. In all 7 of those games the team I bet to start the game was down and looking to double up on big 2nd half. I have seen that in 6 of these games the game resembled the one similar to the first half. Which leads me to the question, is smart to first bet 2nd half lines? Second, if you do, do you use it to hedge your original bet or to double up on your original bet? It seems to after tonight that the only time to bet a 2nd half bet is to hedge against your original pick. Any thoughts?
