Using the information is easy; there are fairly detailed instructions on our website, and substantial additions are being made to the wagering strategy sections in the next week.
If you happen to live anywhere in the world except the US, Pinnacle is probably a good choice. Given the recent legislation regarding Internet gaming, I strongly suggest you either consult your attorney before investing with Pinnacle, or stick to US sites. It is a big issue, because the lure of "rebates" has attracted the attention of a lot of professionals and betting syndicates. As of the time the Internet bill was signed, the majority of those professionals dropped Pinnacle, Betfair, and a host of other offshores like very hot rocks.
The consensus opinion seems to be that given the "tracking" facilities of the Internet, anyone engaging in activity that could be construed as illegal is wishing a heap of hurt on themselves, for very little (if any) advantage.
Specifically, if you are picking winners, you can do every bit as well--with no problems, present or future--by sticking with the legitimate, licensed-in-the-US venues. YouBet is nearly ideal, the only complaint I have heard is that they don't carry some tracks like Philadelphia Park--which has its own venue for wagering that includes the very lucrative Chicago area harness tracks.
Good Luck
