There are 2 equally important parts of handicapping - Who to bet and When to bet them.
Who to bet involves math models, algorithms, analytics, and a gathering of information to put a price or a line on every game. Then compare your line to what's available in the market and bet the games you have an advantage in.
Who to bet can obviously be a lengthy discussion, but When to bet is the next step that most handicappers never take. Let's take the Colts vs Chiefs game as an example. The line is Chiefs -5 or -5.5. The Chiefs are a public darling because of their offense so the public is going to be on them. Then look at the early money showing up on the Chiefs and all indications are that this number is going to -6 eventually. When looking for this information, only use Bookmaker or Pinnacle. Money coming in at BetOnline or 5dimes or anywhere else doesn't matter.
So anticipating the number going to -6 means those looking to bet the Chiefs should do so now at -5 or -5.5. But those looking to bet the Colts should wait for the line to move to get a better number. Now once the line goes to +6 for the Colts doesn't mean you bet right away. Instead, you should look again for where the money is going. If it's still piling in on the Chiefs, continue to wait. Might get +6.5 or possibly +7. The idea is to continue watching line movement and where the money is going at each new number.
But now take a look at the picks on this game here at PM. Two-thirds of the picks are on the Colts. Why would these guys do that? Even if you had no idea which way the line was going to move, why would anyone bet a dog at +5 or +5.5? If the line moves down, you will still get +5 or +4.5. There's no difference between +5.5 and +4.5 because 5 is a dead number in football. But if the number moves up to +6, that's a big difference. So by waiting, there's everything to gain and nothing to lose. Then do some work to discover which way the line is likely to move, and waiting to bet the Colts will be valuable.
Learning When to bet is a step most handicappers never reach because it takes a lot of time and work, but it's very valuable to get the best number possible.
