Machine Learning, so probably it was you who has just posted a 1 star review on Amazon,
without a verified purchase, of course.

You are even mixing up the 2 books, 'Secret of Chess' and 'Human versus Machine',
the one does contain full games and the other does not, but you picked the wrong one for the games...

I wonder why people who HAVE NOT READ the book should write reviews?
Parent - - By MachineLearning (*) [au] Date 2017-11-17 03:29 Edited 2017-11-17 03:34
Sorry. I didn't write the review. That was someone else. Do you want me to write one?
Parent - By Lyudmil Tsvetkov (**) [bg] Date 2017-11-17 03:33
On the contrary, the book WILL STAND the test of time, no matter what its detractors do,
because it is a valuable book, and also a one of a kind book, a trail-blazer.

Machine Learning, I would strongly recommend that you watch your language.
Parent - - By MachineLearning (*) [au] Date 2017-11-17 03:44 Edited 2017-11-17 22:02
I should add that: the reviewer might have got the book from somewhere else other than Amazon. You shouldn't assume all one-star reviewers haven't got your book. In fact, your 5-star reviewers are all your known friends like Michael B. They're biased. What you really have is just one-star reviews.
Parent - - By Lyudmil Tsvetkov (**) [bg] Date 2017-11-18 06:05
In fact, Michaek B has never been a friend of mine, but he might become one now.
If you read talkchess at the beginning of this year, we quarelled a lot about his claims he is + 30 elo
with his McBrain to Stockfish, but he still bought the book.

He bought it, because he is a an intelligent person, a person with experience, and he knows to
distinguish between good and bad things.

All the reviews I have from people who actually read the book, friends or not, are GOOD.
The 2 reviews from persons who DID NOT read the book are 1 star.

when will you stop that?
You are one and the same person here, on hiarcs forum and chess chat, with 3 different names:
- HerO
- Student
- Machine Learning

That is all the support you UGLY denigration campaign has: a single person, not very well educated,
quite probably young and inexperienced, and full of venom.

Can you please tell me, what did I do to you to behave like that?
Did my book kill your selling niche?
Your vision of the world?
What else?

It is good to be negative without a reason, to a certain point, but that much...

PS. Most of the people I know come from talkchess, you are registered there and certainly have an account,
I try to remember who you might be, still unsuccessful, maybe you will reveal your real name...

I know very well what truth you are telling.

You just wrote 2 1-star reviews for the 2 parts of 'Human versus Machine', and another one
for 'The Secret of Chess', under the name Serverless.

But don't you feel ashamed?

I have reported the issue for abuse to Amazon, hope they take the appropriate measures.

God is high above, rest assured you will be appropriately punished.

That's a kind review! Lyudmil, I haven't bought your book. I have enough chess books.

Some years ago I was asked to review a chess book by an author. At the time, I was helping a professor emerita, (this is going back ) who  had gotten the idea of including in the text of this particular  Grandmaster's latest chess book release- an accompanying CD that could  concomitantly be use on a computer  to demonstrate the presenting material .

When I read the book it was fraught with typo's! This was after the author's proof reader had supposedly gone through the book before publication. This is apparently, a fairly common problem with chess books.

Anyhow, the project had to be scrapped as the chess book's author ended up on  "America's Most Wanted"

I think they finally caught up with him in Brazil-giving private lessons to teenage girls! He had the same penchant for fourteen year olds as does Roy Moore! :lol:

Just started reading the review of GM Smerdon and he quotes the book with the following position:

rnbq1rk1/4ppb1/2pp1npp/pp6/3PPP2/2NBBN1P/PPP3P1/R2Q1RK1 w - - 0 1


“In spite of the big development advantage white enjoys, black has already a winning position. And the main reason for this is the familiar central pawn pattern in the form of the e4,e3,f2,g2 pawns. The central e4 black backwardmaker is having a cramping effect upon the entire white king side and renders the white shelter inflexible.”

I have not looked deeply but I would prefer white - am I the only one? :eek:
Parent - - By Chris Whittington (**) [fr] Date 2018-01-23 21:10
No, you haven't looked deeply at all. The Smerdon review clearly attributes the comments you quoted to an entirely different position. You muddle up quotes with diagrams to which they are not related, in a review written by someone else entirely.

The Secret of Chess?

You are correct -this is  Smerdon's review!

I was wrong in my original understand in thinking otherwise! The reason this entire subject gets convoluted is because it starts with -IM Swordfish55 gets handed off to - someone with a handle called " GWTR " who then give a link to the review by Smerdon!

Just copy the entire whole Goddamn exercise:

It follows from his concept of “twice-backwarded pawns” that after 1.c4 e5 2.Nc3 Nf6, White should play 3.e4!, with an advantage. To be honest, I feel that Tsvetkov could be a little biased here by his large experience playing against engines; we know that engines struggle to play blocked positions, so a human would have a better chance of success by trying to close things up as soon as possible. Is 3.e4 objectively as strong against another human? (And, conversely, is 3.e3 as bad a move as Tsvetkov makes out? For example, he gives the position where he says:

“In spite of the big development advantage white enjoys, black has already a winning position. And the main reason for this is the familiar central pawn pattern in the form of the e4,e3,f2,g2 pawns. The central e4 black backwardmaker is having a cramping effect upon the entire white king side and renders the white shelter inflexible.” 


He goes on to explain this rather outrageous claim, which I’ll reprint in full: 

“Top engines, of course, completely misunderstand and misplay the variation. Most of them will still assess above position as very favourable for white, but of course, black is winning. As the associated lines are very deep, engines basically see nothing and rely on their positional evaluation, which is far from perfect and, in many cases, like this one, rudimentary. Winning is pretty much straightforward: black continues with slow attack on the king side, pushing pawns there, and gradually transferring pieces to this focal point, including the ones on the queen side. As the position largely carries a closed character, emphasised by the e4 central backwardmaker, black has all the time in the world for regrouping and coordination. White, on the other hand, can do almost nothing, as the white shelter is inflexible, and attempting to break free with f2-f3 or f2-f4 will easily backfire, creating multiple weaknesses.” 

Of course, in a practical chess game, matters are far from clear. But objectively…? Honestly, I don’t know. I’d need to hear the opinions of correspondence and freestyle chess experts before I’m convinced. But still, I like hearing the way Tsvetkov thinks about these positions, mainly because it’s a new way of evaluation that I haven’t encountered before. And I’m all for diversity.   Here are some other specific examples that I’m sure will have many grandmasters scratching their heads:

Are you on the same page Chris? :smile: ( This whole thing threw me into a tailspin!)
Page 79 from  Lyudmil Tsvetkov book " The Secrets of Chess"  and the comments were apparent form Smerdon's review!

The only challenge you may have  between Hamsters is his  analysis of the position given -but the rest of your comment I'd say -you muddle up!

( Actually we can lay the blame on the party doing the review failing to note his references with at least a page number! Lyudmil wasn't any the more efficient in labeling his example plates. Shame on you Lyudmil!   )

I don't know what this has to do with 'The Secret of Chess', probably the advanced concepts in the book allow me to play well versus top engines,
but here my first draw and first handicap win over SF 9.
Hopefully, when I am in a better sporting from in the summer, I will start winning non-handicap games too.
For the time being, not much time to play chess.

Btw., Dr. X, if you post screenshots, you must have bought the book.
How did you find it, I am interested in your feedback?

Would be interesting to know also from Banned for Life, did you consider the book and how did you find it?
I am just curious, you probably understand me.
Parent - - By Lyudmil Tsvetkov (**) [bg] Date 2018-03-26 14:00
The second volume of 'The Secret of Chess', containing example games, is out.
803 games in total.
The games follow the Table of Contents of the first volume, covering each and every term.
Some terms are covered by a single game, while others, more important ones, by as much as 15.
The volume features 5 world champions, among which Carlsen, Kasparov and Fischer, 3 top engines, Stockfish, Houdini and Komodo, as well as a number of other players.
I have browsed 15 000 games to carefully select those 803.
All games are tactical and positional masterpieces.

The book is available here: https://www.amazon.com/Secret-Chess-Example-Games-ebook/dp/B07BJLMZ6V/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1522071381&sr=1-1&dpID=51yVGVku9cL&preST=_SY445_QL70_&dpSrc=srch

I guess everyone, programmer or chess player, who has found the first volume interesting or would like to clear his ideas on the concepts, should have a look at this one.
For the time being, the games are unannotated. It will take couple of years to fully comment 800 games, so I wanted to have this consolidated version out.
I guess at some point there will be also a volume with annotated example games, but this will not be too soon. And I am not certain what portion of the games will be featured there, probably just a smaller one.
The main reason for releasing this volume is that many people asked me for illustrative games to better comprehend the concepts. Initially, I had not considered this at all.

Just to mention that the comparison between top engine and human play in the collection is an interesting observation.
We all know that top engine games last much longer on average, and the collection will only corroborate that.
But there is one more interesting phenomenon I discovered, namely that top engines tend to use some terms more often than humans,
that would concern in particular for some reason outposts, especially more advanced ones, and material imbalances.
Why so?
Still not fully certain, but maybe one of the reasons is that the human imagination on average will have bigger problems with some lines, requiring deeper or highly unusual calculation.
So that chess changes, there is no doubt about that, and we will be seeing further very interesting developments in the future conceptually, no doubt about that.

I have reviewed vol. 1 on Amazon. Lyudmil, please don't bother much with the naysayers.

New concepts anger most people. who don't want to take the trouble to understand these new ideas.

BTW, it is also essential that you maintain asmFish updates into the future.

Many thanks, dear sir.
Your second sentence might indeed be revealing.
I owe you for you kindness and good words.

I wanted to post a game, to illustrate how the second volume covers the concepts.
Below game covers the 'spearhead connected passer' term.

No one tried to refute Bxa4 wins for black, that is interesting.

Here is what I get in a single try by SF 9, but of course, there are improvements for both sides.
The point is, the knowledge contained in the 'spearhead connected passer' is there and objective,
it kicks in at some point, changing the evalution from positive to negative.
Search is unable to help SF very much here, as the lines are very deep, running into the 60+ plies.
