This link is to the Chess Hustler forum. From there it shows you how to download the entire book. The opening below is mentioned on page 3 and is Ruy Lopez [C82].
To this point, I wonder why black on move 4 delayed b6 and why on move 5 white castles rather than protecting e4?What do you think?
Do you play the book line?
