I don't know what it is about poker books, but I buy them for the hell of it. I probably have more invested in poker books than basket's networth. Most of these books are worthless, but the latest book I picked up is a true gem. Phil Gordon's Gold Book truly introduces advanced strategy and mathematics, whereas many of the other books in my collection claim to but are really shallow. Check it out....guarantee many of you will enjoy, unless math is too boring for you.
