Blockhead-
I only play unders in the 2H, but I am not taking the under in those games regardless of what happens in the 1H. I anayze each game at halftime before I make a play. I also have some pre-game indicators that alert me to stay away from the 2H, no matter what. So, that leaves me with 3 "potential" plays tonight.
I really like Cleveland -8.5 1H tonight and played it just now. Will keep the 2H record separate from any "side" action plays.
