What books are you talking about . . .
This is the only one i know of and there are three version . . .
A Complete Opening Repertoire for Black and White
Sort:
No, the 3 boards linked above are opening repertoires for everyone to use. You can download the PGN's with the little download icon.
So I downloaded one of them and it was able to be opened by the chess game i have dl, and it was like one board? Idk what u are talking about, but I thought you were talking about like hundreds or thousands of games...?
What did you open it in those files have around 100 lines each.
The way I did it was go to chessable and click create a course, and then import the pgn, and look at the lines there.
what's a line?
A line is one of his games.
I just opened it with some random chess game that I downloaded from the windows store, was prty surprised it worked but it recognized the file I could tell cause the file showed up with its icon. prog is called "the chess lv. 100"
@Mr_Winawer I set the "Event" to the opening name so you can select that from advanced in chessable import section and it'll name the Variations. The go to "Ensure Quality" and have it automatically select the "Key Moves". Do once for White of your choice and Once for Black.

Najdorf is more popular and even that only goes to 13. move 25. can be a book move but the chances of you remembering it and your opponent following the line...
I added instructions for setting up a opening trainer course on chessable

Yugoslav Is too strong. But have you seen how deep in theory some najdorf books go. The winawer also goes super deep
Not surprisingly those are some of the longest lines the algorithm selected. Along with the Spanish.
but the spanish is very straight foward, and every move is logical
Thank you for this @JosephDouce, I've just got myself a chessable account with a view to building up my repertoire book and actually learning some openings so this has saved me a heap of time. I guess the next thing to do with these now that I've added them would be to add comments regarding the theory behind the moves etc - why they're considered good moves and so forth as opposed to just a straightforward rote learning of the move sequences
Thank you very much for this, @JosephDouce! This is extremely generous of you.
On a tangent, I've been amazed at how hard it is to computerize the practice a subset of openings, "nudging" the computer to play within those openings, ideally moving from line to line. This must have to do with forcing the computer to play from a specific opening book, but try as I may, I can't figure out how to get HIARCS Chess Explorer or other engines (I'm on Mac) to do this. Any suggestions?

indeed. I'm all for a Practical Chess Opening Repertoire for Everyone, but I am afraid that even in this Age of Information THIS type of undertaking will ultimately fail. Statistics are not reliable measures. It is only the Accumulation of averages in a certain range of wins-losses ratios. It does not specify circumstances where one blundered outright, deviated, miscalculated. Nor does it isolate experience between the two combatants, adaptability, intuitive ability or plain common sense. Familiarity of the opening played. Experience playing said opening. How can one glean that from a bunch of numbers?
I know I'm discovering this over a year after you originally shared it, but I'm confused, is this supposed to be a repertoire or just a list of the most common opening lines? I ask because I'm become very interested in this data-driven approach to building and evaluating an opening repertoire. However, this doesn't seem like a repertoire.
E.g. for Black you list 4 different responses to 1.e4, and following the 1...e5 line it doesn't even list a response to openings as basic and common as the Four Knights Scotch or the Evans Gambit. Hardly seems complete!
Likewise for White, following the 1.e4 repertoire goes into the Ruy Lopez, the Italian, AND the Scotch after 1.e4 e5 2.Nf3 Nc6?
This seems more like a descriptive data project than a repertoire!
My goal here was to produce a comprehensive repertoire for everyone, covering as much ground as possible in the minimum number of lines. Efficiently preparing for the most possible scenarios with the minimum amount of work.
There are no opinions in this book, these lines were derived from statistical analysis of over 100k games played of rating 1600-2500 in 2019/2020 and choosing the most popular 95% it is stunning how few openings are actually played. The result was approx 300 lines covering 95% of games encountered.
Black: 91 lines covering 85% of games
White 1. d4: 84 lines covering 85% of games
White 1. e4: 86 lines covering 94% of games
It is not to say that you'll never encounter anything else, but the aim here is to be prepared for the first 10 moves of as many games as possible.
There are a lot of lines but many only have 1 or 2 key moves as the mainline covers the majority of the moves.
The majority of lines don't extend beyond 10 ply.
The Data
The best way I have found to practice this is to create a free account on chessable then follow the below steps, which take about 5 minutes
Repeat for Black/White
I tried to publish it as a free course but they want 3 months to review it.
