Hi everyone,
Grandmaster David Smerdon just wrote a detailed, lengthy, and balanced review that was complimentary (with critiques as well) of Ludmil Tsvetkov's book, The Secret of Chess.
I'll take a second look at the book after reading that review
The review is also available here:

Well, chess is still mostly in its infancy, believe it or not.

Lets look at a random review of this book from Amazon:
"This is a very bad book. The author had not shown his knowledge in computer chess, everything was just random guesses. The author claimed he's a very strong GM+ level player in the book. Do you believe it? An untitled player suddenly playing at GM level?? Unless you believe Lyudmil Tsvetkov (the author) is really a grandmaster, nothing in the book should convince you. If the author can't even properly self-introduce himself, why would you think the contents are worth your time?
Throughout the book, Lyudmil is trying to show how he plays better chess than Stockfish, an 3000+ ELO chess engine. We don't know if the games are real, in fact my Stockfish 8.0 don't agree the Stockfish moves in the book. Apparently, the games are fake - anybody with a laptop can make a PGN with some random moves, then change the player name to "Stockfish".
The contents have not been proof-read - grammar, spelling mistakes everywhere, but that's not the problem. For example, the author claims the advanced French variation is a "forced" loss for Black. Are you serious? 1.e4 e6 2.d4 d5 3.e5 is a win for White?? Are you serious? Unfortunately, there're many other similar examples. The authors has made countless random guesses in chess.
There's no "secret" in this book, and there's no value. Please don't bother, and waste your time."

No, but does that matter when the book is not written by a GM ?

How are you not ashamed?
This review was posted by a 13-year old boy, who did not even buy the book(his purchase is not verified). He posted 4 1-star reviews for all my books, because he hates me for some reason. But I guess they will get deleted soon, I am awaiting a response from Amazon.
Where do you see spelling mistakes everywhere? Illegal positions everywhere?
He is lying, just like you, because you are both very weak players and envious of anything new and original.
Because, to write something original, it takes strength, courage, knowledge and an unbelievable amount of hard work. As you possess none of those, you simply prefer to denigrade instead...
Why did not you post another review, from a person with a verified purchase(that is one, who indeed has read the book):
Mr. Tsvetkov is a Bulgarian chess player and computer chess expert and author. A few years ago he published a Chess Evaluation Compendium and more recently the book The Secret of Chess, followed by his Human vs Machine series, which I'm reviewing here.
In these latest books, Mr Tsvetkov publishes some his best wins against top computer programs. The author shows himself to be not only a very skilled chess player, but also an expert anti-computer specialist. It is well known that today's top chess programs have been far stronger than the best human players, and defeating them is no mean feat, regardless of the playing conditions. Mr Tsvetkov's strong playing ability and high-level chess understanding come through very clearly when going over the games, which feature lucid and instructive annotations.
The games themselves are masterpieces of strategic attacking chess, and I can't help but notice how the authors strategies can be relevant when facing both human and computer opponents. Although the opening systems adopted work best mostly when facing a chess program, they are very sound and effective enough to be deployed against anybody, so the student of the game can learn a lot from reading these books and then proceed to apply this refined knowledge in his own games. Here I am speaking as a strong player myself. There are a lot of good, even titled, chess players that do not excel at defeating computer opponents, and in fact struggle mightily, who could find this work inspiring, as well.
I should add that Mr. Tsvetkov is not the first author to be renowned for writing a book about beating the strongest computer engines. Years ago, Dr. Ernest F. Pecci, M.D., a chess amateur, wrote a book on how to defeat Fritz, the top chess program of his day, and the foreword was written by none other than world champion Garry Kasparov. It should clear that playing against computers requires specialized skills, which these books do an excellent job of teaching. It is for this reason and many others that I find the negative reviews here, that seek to detract from these fine works, and by people who have never bought or read the books, very suspect as they don't do justice to the author's works.
The author has shown himself repeatedly to be a computer expert and knowledgeable about the programs' playing weaknesses, with his helpful suggestions being incorporated into Stockfish, the world's top free program, and contributing to its further success, and also praised by Mark Lefler, programmer of top commercial chess engine Komodo. Mr. Tsvetkov does have a track record and his books and other contributions to computer chess speak for themselves. He has basically uncovered and exploited the chess engines' hidden weak points, but also shown and suggested working solutions to remedy these problems. This is a remarkable achievement, in my opinion.
All in all, I highly recommend these books. You'll know more about chess as you read them.
That person has read my books, you know, and is not just spiteful and envious.
No matter how low-thinking one must be, one should first check things.
I forgot to mention, he posted 4 1-star reviews.
Why did he bought a second book of mine, when the first was so awful?
And then, a third? Does not make sense, does it?
So, you have faith in a random malicious boy rather than GM Smerdon?
Of course, my book is difficult to understand, it is not for everyone.
You will not understand it even in 20 years' time.

Yes, it does.
A 1400-player like you can not review much stronger players, I think this is clear.
I am completely disgusted by you, I know some people are shameless, but to such a horrendous degree...
You have the right to review a book, when you have read it.

An unrated player like you who never played a single game of chess can NOT write a chessbook. Yes, I read the preview on amazon. The preface was enough to convince me what a scam it is.

Like the author said " how can you judge if you have not read the book". Least we forget that a plumber proved the most renowned physicist in the world wrong. So GM should not mean so much. Smurfo gave it a interesting review. I'll take his word on that it was interesting and fresh. So before you try and discredit someone have a little more than the superficial ammo or you are the one who seems dumb!!!!!!!!
Ok, after reading all that I can say that this guy is a total scam. He claims that he can beat Stockfish but doesn't gives us any proof; he doesn't have any FIDE title, and he doesn't even have a chess.com rating. In the internet you can't find anything about him other than dubious information generated by himself or by other empty profiles. Don't buy this course, people. Don't be naive.

Lets look at a random review of this book from Amazon:
It's misleading to call that a random review. It's one of two negative reviews. The other five are positive. But I wouldn't put any faith in just seven reviews. I'm sure an author's friends will give good reviews, which won't make much of a difference if there are hundreds or thousands of reviews.

Of course, my book is difficult to understand, it is not for everyone.
You will not understand it even in 20 years' time.
"Learn chess 5 times easier through pattern recognition," according to the book's preface posted on Amazon. How does that square with your comments above?
The evidence is clear, I am the only living person, so far, who is able to beat the top chess engines.
What more do you want?
What evidence is clear? Claims are not evidence. Is there any independent evidence that you're the only living person who is able to beat the top chess engines?
