Query: Not good

The problem with the other customer reviews here are that they are all by beginners who don't know any better. I ordered this book as a beginner and started to believe what the book was saying. Later, I searched for info about the book on the backgammon newsgroup. The overwhelming response from experts was that it is a horrible book for learning backgammon. Much of the info in the book SOUNDS like good advice, but is simply wrong. He makes the "rollover" rule that he introduces sound like a very common and accepted rule. That is just not the case. He also over-simplifies things and makes blanket statements that are only true some of the time. I would suggest finding a copy of Magirel's "Backgammon" instead.
