I have come to the conclussion that this book is mainly for the players over 2000 not for lower rated players. You must be able to follow the variation in your head.
Otherwise you must have a board at least two boards with the game set up so that you can see the moves and then revert back to the original board.

Do you actually know? Or do you play Against it by the hair of your chini chin chin? . . . . . Like I do? , , , , ,
Playing against D4 has been a puzzle to me since I began playing 63 years ago and playing it I seldom did. Although just this year I have made it a demand of myself to play D4 whenever I play white even if I lose.
I could nothave written a review of this book that I purchased in 2013. I kept trying to force myself to read and play it. But it is not amature friendly. It is a hard book to play and remember all the variations.
"The Chess advantage in Black and White" Printed in 2003 By Grandmaster Kaufmann.
I didn't want to pay $30.00 so I kept waiting. One day I decided I would get it anyway.
By luck I found it for $10.00 but by then it was an old version.
So I got a new used version of the NEW 2012 hard copy on Amazom
I like a hand held book better that e copies. It came immaculate just like new. What a bargain.
The Black part is on one side and you flip the book and the white side is there.
The only problem I dislike that it is not for amatures. It's mostly directed to players over 2000+. It is focused on the D4 opennings but it covers some E4 opennings on the black side.
So the front part WHITE is tries to show the play that gives you the advantage as white using the D4 openning. Then on the BLACK side it gives the best suggested play as a defender playing against the D4 openning.
I thought it would be a great book but I have not even gone through one game of the White instruction. It says it is user friendly but I must not be that user friendly.
The description uses several styles of annotation.
It puts a little photo of the piece and its location and where it is to be moved.
b2-b4 Ng8-f6 photo of the piece with location for the
N . . . .. If it's a Queen etc.
Normal it's 1. b4 Nf6 and that is easy.
I just dislike all the little photos with the location where it is at before the actual move. What a pain the whole book is.
Kaufman a grandmaster uses computers and his experience for variations. He also covers E4 suggestion variations in current use.
I would look at the book first for FREE before buying.

I keep buying books because I like to read hand held copies. I have two kindles but I never read books like that. So in a few years I probably will give my books away again.
Tell me about openning books might you have read and played.
