Query: essential read for home group poker players

The book is all of the above -- but I feel that it is an essential read for anyone hosting a home poker group. The host can't possibly know everyone who shows up every week and the number of available cheating techniques is so vast that simply "cutting the cards" to prevent cheating is nothing short of delusional. For that reason, I rate it highly and could care less if Dickie is fictional or not. The cheating techniques are real enough.
