@shallow-blue saidDid you get the hardcover or the softcover? I have both, and it is far easier to beat your computer with the hardcover version.
I don't know what the greatest chess book ever is, but I've recently started dipping back into what may well be the largest: Susan's father's Chess Training in 5333+1 Positions. If it doesn't help you beat your opponent over the board, you can use it to break his skull.
