вот как работет Пинакл:
Pinnacle Sports employs the most talented handicappers in the world who open betting lines on a market. Initially the limits are a little smaller than their massive norm, such a $5K or $10K US per bet. They then adjust the lines as they take bets looking for a spot that their known winners have no interest in betting, because neither side is +EV.
The way Pinnacle moves the lines is genius as it involves advanced algorithms that consider: who is the player making the bet, how much is he betting, when and why. In other words, user profiling is just as much, if not more, a factor as how much is being bet on a side. Their confidence level is that they can reach the place neither side is +EV and then profit long term from the small markup which is less than what other bookmakers charge. While this seemed like a crazy idea in 2004/2005 today it's how betting works. Pinnacle discovered that when unrestricted (example: limit collars) betting is a market and functions as such. To make the most profit Pinnacle just needed to find more savvy sports bettors.
