What I would have thought. Serves the authors right for using the lazy game format for a book also.

I still need to work on the selection process and ordering of games.

I like that your notation encodes the color of each move, even if the move-pair number is ignored. Years ago I took to doing this with letters; and the color encoding definitely reduces errors in recording and replay.

If your color-specific figurine LAN notation also included the type of piece taken, your notation would be fully informative by the test of Reversibility: given the end position, a person could replay the game in reverse.

One position diagram per move (not move-pair) is nicely thorough.

I like the yellow origin and destination squares.
? How did you color the squares, I wonder. It does not seem that each diagram is an image file (.jpg or .gif or .pgn), so How?

Is the font Chess Alpha 2?

I suspect the .EPub book would be handier as a plain .PGN file, because we all own Fritz (or equivalent). I see nothing in the book beyond what Fritz would show after opening the .PGN.

The book needs some kind of table or tree to show where in the opening each game deviates from the others.

Thanks for the feedback.

Under the covers .epub is a subset of html, so all formatting is done with css and html. 

My font is my variation of Chess Alpha (Erik Bensen). I had trouble with the base Chess Alpha working in some of the things I am doing, so I fiddled with the font.

I am still thinking through the best way to document where a game diverges from the repertoire. Most of the things I have come up with do not work well with the outside tools I am using right now.

This project is an offshoot of a main project which is a web page where one could define their own repertoire and have an ebook created based on their own search.

You may have noted that the next move below the diagram is a link to the next position. The hooks are in my format to have variations, which might be the way. Unfortunately, Epub does not work too well for non linear pages. I am still working on that.

The utility in an ebook over a pgn, is that you can review games with an ebook reader on a device (like a phone) on which one does not have a good .pgn viewer.

My digest would not be of games from the book, but from later (recent) games.

Hi, I am preparing to use the Kaufman for Black against 1.e4 and may add other portions as time goes on.

I have made .epub files of games I have extracted from recent databases with a collection of Tabiya. I was wondering how useful this would be to a general audience.

Each move is presented with a separate diagram, so no set is needed to follow the games, and I use a chess font, so the files do not get huge.

Well, I have the book and I would love to have this file, but surely there are copyright problems for people who don't have the book?


game scores are not copyright protected  ... only if intellectual property such as kaufman's published analysis is used would it be a violation

It is just a collection of recent games. You would need the book to understand how a particular game fits in the repertoire.

If I included the set of tabiya, or a .pgn of the tree, there might be a problem. But even with that, I would think it would be necessary to have Kaufman's book to really get a use of my game digest.

I need to make a few more posts before I can put up a link to a sample. I have mostly lurked till now.

Hello my chess friends!

Happy Easter to everyone  Smiley

Regarding Kaufman's book, hod did you fare with proposed repertoire in practice? 

I'm aware that the author couldn't encompass all minor lines cause in that case he would need cca 1000 pages.

Judging the book by mentioning in majority of cases the main lines, I came to the conclusion that Kaufman targeted the 2000+++ audience!

Thanks for replies!

Gilchrist, Nikos! Come on ... Cool

The result of this decision by Kaufman is that the lines are poorly explained and - because of space constraints exacerbated by the bizarre decision to use a full-games format - don't cover deviations that, while no doubt sub-optimal, are just the sort of moves that one might encounter in club chess.

I have to agree that the full-games format (where he often stops quoting the game because someone played a bad move (!)) is a bit weird, and if you were looking for good explanations this is clearly the wrong book, but I still think he gives some interesting suggestions, which you should still check for yourself

I think a repertoire book is not more than a starting point and Kaufman's book is among the best repertoire books. 

But Kaufman's book is not advertised as a 'starting point'. It is advertised as a "Complete, sound, and user-friendly chess opening repertoire". That's the standard, therefore, against which I judge it. If I'd wanted a 'starting-point', I might have spent my money elsewhere, or done my own research.

I'm very disappointed with the book, and judging from the 'bashing' in this thread, I'm not alone. It seems to me that the criticism of the book in this thread is valuable to a prospective consumer.

emary wrote on 09/01/12 at 18:20:36:

I have chosen the first option a few times and this line scores 
incredibly well (much better than the Slow Slav) in praxis [etc.]

As far as I can see Kaufman has chosen very theoretically sound lines for most things (although some other posters disagree). My problem is not with the quality of the lines Kaufman advocates, which in fact seem to be used regularly by GMs. My problem is with the appropriateness of these lines in a repertoire book aimed at amateurs; a book that also seeks to cram a whole White and Black repertoire between two covers. 

The result of this decision by Kaufman is that the lines are poorly explained and - because of space constraints exacerbated by the bizarre decision to use a full-games format - don't cover deviations that, while no doubt sub-optimal, are just the sort of moves that one might encounter in club chess.

I think a repertoire book is not more than a starting point and Kaufman's book is among the best repertoire books.  

I agree that Cox' book "Play 1.d4" is a great book, maybe even better than Kaufman's. For example his lines against the Dutch have served me very, very well. But I really don't like that there has been some bashing against Kaufman's book in this thread. 

I think Kaufman did a very good job in the Semislav/Slav complex. 
It is very sensible to offer a backup-repertoire against these complicated lines: 

Kaufman suggests 
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Qc2 or Qb3 
and 
1.d4 d5 2.c4 e6 3.Nc3 c6 4.e4 dxe4 5.Nxe4 Bb4+ 6.Nc3 

I have chosen the first option a few times and this line scores 
incredibly well (much better than the Slow Slav) in praxis 
(at least beyond 2000).  
The second option has more bite than the lame 4.c4xd5 used 
my many White players in praxis. 

His Catalan-like handling of the Ne5-Slav is also very reasonable.  
I have played many blitz- and rapidgames in this line. White has a 
space advantage and has a relatively safe position. Of course the Slav is a hard nut and White has a modest advantage at best, but 
I think Black is under a little pressure. 

Kaufman's handling of the Bg5-Semislav is over all pragmatic and good. 

In the Botwinnik there are holes of course. 

But you must not forget that after 
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 dxc4 
Black has already reached the point of no return. White can still play 
the solid 6.a4 if he doesn't want a theoretical battle. 

Cox says it very well in his book: "Play 5.Bg5, it is a good move ..."
