There is only a handul, less than 20 in my opinion, that really cause the Don Best screen to turn black. Fade those guys and you will go broke. If they lay 4 and you lay 4 or 4.5 you should win. But what happens is they lay 4, the followers lay 4.5, 5, 5.5 and maybe even 6. Now if someone comes in and takes the 5's and above he has tremendous value and has a great shot of winning.
The other problem with steam is the false moves. Billy Walters will make a bet to turn the screen black, followers steam the line from 4 to 6 when the whole time he wanted the dog. Once the line moves to 6 he will bet + 6 for 10 times what he laid the 4.
There is no easy way to earn at sportsbetting especially the American sports and just subscribing to Don Best and watching line moves is not the key to the vault.
