22. Sep 2023: New CTG Book by Solista: Nightlife.ctg. This book covers the best ENG games from the last 3 months on PlayChess.com. Also included are all the latest killer and anti-killer variants from the last 3 years! The book is very suitable for tournament play on PlayChess.com. Why Nightlife? Me and my friends play in automatic mode. This also makes it possible to play at night. There is also nightlife on the server. If you are interested in the book then write me an email (see contact). I charge a fee of 10 euros (PayPal) for our electricity costs and the maintenance of the books. The book has a size of 64 MB (ZIP 20 MB).

New opening books by Solista:

How do I create my books? I would like to give a short answer to this question. I have been developing opening books in CTG, BIN and BIX formats for several years. I work with some good friends who play a lot on servers. The hardware used goes up to 64 cores. My friends are currently playing with 8 to 44 cores. I myself play with 8 to 12 cores and a laptop with around 1400 kns (Stockfish) so that I can also develop a book for slow hardware. Some of my friends also use Lc0 as engine. The hardware used is currently an RTX 4090.

I maintain a basic database with the most important killer variations, draw variations and winning variations that are important for every book. This database currently consists of around 3300 games. I receive thousands of server games from my friends every month. I play myself too, and I also kibitz. From this I create a few hundred important winning and draw variants every month, which I add to my base book (and also in other books). Most games end in a draw. That's why I almost only use winning variants now. But here too I select: I delete games against very weak opponents. I also delete all winnings due to disconnects or time and big blunder. I implement the rest into the book, after which I check each book move manually. If new, good variations emerge, I have to mark them green as tournament moves. If there are refutations of variants, then I have to revise them by hand.

I fail to understand the purpose of this project, can you explain?

[Eduard]

What purpose do other projects such as: the Hiarcs book or the ChessBase books that you can buy?

My books are based on engine games, of which there are millions. Thousands of games are played every day on servers like PlayChess.com alone. There is fighting but also a lot of testing. Tournaments will also take place on the server again. In the past I have played in prize tournaments on InfinityChess.

Because a lot of games are played on the server, the quality of the games is extremely high. Nowadays it is no longer even possible to win with 1. e4 against 1...Nc6. Wanna bet? I like to have a duel on the server.

My goal is to complement all openings with the very best engine games. My big book "Solista-ENG PRO-v3.CTG" contains all the best variants and all openings. The move sequence like 1. e4 a6 is also in the book, and I'm sure that White won't win there either. If you want to see the best of what the engines play, you can see it all in this book. My Solista Attack book (CTG and BIN) is a pure tournament book that only contains the strongest moves of normal theory (i.e. without a6 etc.).

[Eduard]

Example: If you play 1. e4, my Big Book will play this:


You can learn a lot. You can learn how to play even 1. e4 1..a6 and 1...Nc6 well. But also everything else, of course! The book is 700 MB in size and all games were played by engines. I also edited and analyzed all variants by hand (not only a few first moves of the variants)!

You gave a good explanation for your project, thank you very much.
I think somewhat differently, I will explain. 1. …Nc6 is somehow completely pointless IMHO as White can simply reply with 2. Nf3 and you will have a hard time to find something better than 2….e5 in response. You avoided no line you don’t want to see with black but you got the additional work to make 1. E4 Nc6 2. D4 work. This is well conceivable to be doeable, although I am still a bit sceptical personally. I wouldn’t be able to prove anything „on the server“ anyway, I only have an old laptop I can use.
But once you already have any new potential opening idea in your book, I can simply look things up there, thanks for your work.

[Eduard]

As a human, I don't play 1...Nc6 either. I don't usually play this with engines either. Reason: I also want to win with black pieces.

Anyone who plays with engines on the server knows that it is not possible to win with black with the following openings: French, Caro-Kann, Modern Defense, Pirc, Scandinavian, Alekhine, Grünfeld, King's Indian, Benoni, Dutch.

Against 1. e4 you should always play 1...e5 or 1...c5 with engines to win.

For this I have developed a tournament book in the CTG and BIN formats, Solista Attack.

If you want to play the same thing with my big book, you can always create a duplicate of the book and block the openings mentioned with red color. The big book contains everything! But nobody must to play everything. Anyone can block any openings they don't like. So I don't know where the problem is? The CTG book can be edited wonderfully. With a single click you can mark the move 1...Nc6 with a "?", and this opening will then not be played. If you "?" remove it, it will play again.

[Eduard]

I constantly implement interesting variants into the book. Here's an example from today. The following position emerged today on the PlayChess.com server in a Blitzgame (evans gambit):

DIAGRAM


White to move:
r3r3/2p3pp/2k1b3/1pBpPq2/2n5/1Q6/4B1PP/R2R2K1 w - - 0 35

What is the best move for White and how long does your engine take to make it?
(I keep myself busy with this and it never gets boring)

[Eduard]

Game was played between Stockfish dev and Stockfish 16. Stockfish 16 was blind to see the win for white, and losed the game.

After the same time SF 16 sees no loss, but SF dev is at +1.50. So this variant is won for white. Stockfish 16 is no longer enough to see this! I don't know why many still rely on Stockfish 16, I know some correspondence chess players who analyze with Stockfish 16 and believe they have the best engine with it.
