With all due respect for my old friend 'Bobby' from EE....Here's the best advice I've ever rec'd in forum land....7 odd years ago.

Bobby's Halftime Cookbook, chapters 1-4
<hr style="color: rgb(209, 209, 225); background-color: rgb(209, 209, 225);" size="1"> <!-- / icon and title --> <!-- message --> I've been doing OK with halftime bets, and someone asked me how I arrived at my selections. Here's how:
First, I make my number. Then I see what number the books put out. If we're off by more than a point or so, I've got a play.
Before we go into how I make MY numbers, we must first look at how the books arrive at THEIR numbers. Their way is much simpler, and can be summed up in one sentence:
They look at their Don Best screen, and copy the numbers from CRIS and Olympic.
That's how much thought they put into their opening number. ZERO. Mindless copying. They don't know how to discern a bad number from the good ones, so they don't even try. So if CRIS or Olympic makes a bad number, the industry just follows along mindlessly, and can be exploited.
But a mistake by either of these influential books also affects the *other's* line. If Olympic says Pick, and CRIS says -2, then ONE of them has a bad number. And each book, aware of the other's number, will start to lean into each other, in an effort to thwart players who are looking for middles. In our example, Olympic might go to -½ or -1, without taking a bet (why give a middler "pick" when he'll happily take -½?); and CRIS would come down to -1½ or -1.
If they don't eventually arrive at the same number before taking a bet, they will be further pressured by the smart shoppers. The favorite bettors will avoid CRIS' higher number, and bet at Olympic. The dog bettors will pass on Oly's lower number, and bet CRIS'. Neither book will get the balanced action they strive for, and will adjust their numbers. Of course, these adjustments bring the numbers still closer together.
The point is, ONE of these books had a better opening number than the other, but moved AWAY from the right side, and TOWARDS the wrong side.
I've strayed from the topic already? Sorry.
OK then, how do CRIS and Olympic arrive at their (the industry's) opening numbers?
They consider the current score, and the game's pointspread. This puts the Halftime in one of the following catagories:
--Favorite is winning, but not covering
--Favorite is winning, and the current lead is about the same size as the game's spread
--Favorite is winning by more than the spread
--Favorite is winning by MUCH more than the spread (about double)
--Favorite is winning by MUCH more than double the spread
--Game is tied
--Dog is winning by less than the spread
--Dog is winning by about the spread
--Dog is winning by more than the spread
--Dog is winning by MUCH more than the spread
Thought this was going to be easy, huh? I warned you that this would be an "epic".
(Just remember, this "cookbook" comes with no guarantees. It's what I've been using, and it's been working for a VERY short time. It's very possible that I've just been getting lucky.)
Let's take them one by one, starting with the easiest.
THE GAME IS TIED. In general, the favorite should be favored in the second half, and the line should be about 2/3 of the game's spread. EXAMPLE: Duke is favored by -7½ over North Carolina. If the game is tied, the halftime line should be Duke -5.
If the spread is very small (-1, -1½, -2), it's OK to make the HT line the same as the game line.
If the spread is very large (say, -20 or higher), then the HT line should be LESS than two-thirds. Obviously, the big favorite didn't bring their A-game if they haven't pulled away from the 20-point dog yet. In these cases, the number should be a little more than HALF the game's spread.
Got it? Don't read any further if you don't. Go back and read the last 3 paragraphs again. It only gets more complicated from here. If you decide to go no further, then "Thanks for playing." For the rest of you, the next easiest catagorie is:
FAVORITE IS WINNING BY ABOUT HALF THE SPREAD (within a point). This one's easy. If Duke's favored by -7½, and they've got a 4-point lead at the half, what should the second-half line be?
If you said, "Duke -3½", you win! And if the book offers "Duke -2", you've got a play!
Simply put, the second half line SHOULD be half of the game's spread, unless the score dictates an adjustment. When the first half bets "land on the number", there is absolutely no reason to come back in the HT with a different number.
If the first half number misses, then you need to adjust. If it missed by a little, you only adjust a little.
Let's take a 12-point favorite:
If fav is winning by 6, HT # should be 6 (duh).
If fav is winning by 7, HT # should be 5½ (not 5!).
If fav is winning by 5, HT # should be 6½ (not 7!).
If the current lead is any other number, then we will not address it here in the "about half the spread" catagorie.
There's one more "easy" catagorie:
FAVORITE IS WINNING BY EXACTLY THE GAME SPREAD. If it's a small spread (-1 or -2), make the second half pick'em. For most spreads, use a number that is 1/3 of the game's spread. In our "Duke -7½" example, if Duke is winning by 7 or 8 at halftime, the HT line should be Duke -2½.
Why shouldn't the HT *always* be pick'em if the game's on the number now? Because if they want Duke, they're going to have to lay something. Laying half the game's spread is a little heavy; one-third is about right.
**********
If anybody is still reading this, and actually paying attention to the numbers, just post here, and I'll type up the rest of this. But if I've already lost everybody, there's no sense in typing any further.
