Pinnacle Sports is a large bookmaker who advertise themselves as a bookmaker who welcome winners - basically they won't close your account if you are a long term winner as they use sharp bettors betting patterns to sharpen their markets which would seem to be a winning strategy as although their revenues are kept private it is estimated that their gross revenue is in excess of $1bn.
In order to further this company image they post short but quite informative articles on their website to help betters educate themselves and become more profitable.
