One should bet on whatever gives you an edge, be it quarter, half, or full games. Here is an example on betting second halves:
If the strong favorite is down for the first half, and down by a good amount, I will sometimes take them in the second half, since I'm presuming that they will come back, win the game, and might even cover the game spread. In any case, the second half bet in this situation is a very good bet, imo.
I got a line of -11 for Utah last night or -3 1Q. The 1Q bet would hypothetically give a full game line of -12.
The advantage of the 1Q bet is the push on -3 which extrapolated full game equates to a push at -9 and -10 (-9 and -10 are losers on the regular full game bet.).
The cost here is the -12 scenario which the full game bet cashes and the 1Q bet pushes.
All of this is based on the (crazy???) assumption that you can extrapolate spreads.
Also...if tmA has a stronger starting 5 than tmB you get the benefit of this advantage for several (or many...depending on the coach) minutes at the start of the game. Phoenix is a very different team for the first 9 or 10 minutes of the game before Nash goes off for his regular late 1Q-early 2Q rest. We've all seen Nash sub out>Dragic sub in>lead shrink...it's like clockwork.
Also...there is the 'pumped' factor. TmA is in front of home crowd>tmA's coach is the 'foot-on-the-neck' style (ie Gerry Sloan)>tmB wants to ease into the game (rough road trip/bad chemistry/bad work ethic etc.). All it takes is one good run and the 1Q bet will cash.
Wouldn't these (or other) factors give the 1Q bet a slight edge...if you got a line like the one above?
I find 2nd halves to be my best opportunity to cash in the NBA. I'm not great at picking full games unless it's a DUH type of line. 2nd half wagers allow me the opportunity to look at the 1st half stats, score, situation, etc. and make a better educated guess on where the game goes from that point. I think this is especially helpful for any game that features teams with back-2-backs or injuries where you have no idea how they will respond until they hit the court.
Too much anger around here. My point is that I cap the game and make my bet and ride it out. What I see are so many here that bet 1st qtr and when they lose they bet 3rd qtr and so on chasing their losses. If you bet like that good luck to you. I I feel better winning at the end then losing on some nonsense first qtr bs. Peace
