I'm looking for a couple suggestions--or reviews of any kind, even if they are negative--about literature or books related to sports betting... ideally something I could find at Amazon or at least order from an older used book store. I know a lot of these tend to be pretty hit or miss, and it's especially tough because the one or two reviews you'll find from the big websites are usually by guys just learning the basics for the first time. I'm definitely an experienced gambler, been doing this for years now, so I don't need a "how-to" or a "insider bookies vocabulary" type thing... just something that could potentially offer some more good advice or an extra edge. Any help is appreciated.
