Hello there, the book has been updated to versuon 2.1, including only computer games from 2014 and grand masters rated at least 2500: the result is a lighter book (124 MB) with stronger variants, my intuition was correct.

Yesterday I've made a public challenge on Twitch again the latest Cerebellum_light, the once stronger opening book available, my book has won by 2 points. Here you can find the latest part of the games and all the games databases archives: http://chess.massimilianogoi.com/videos.php#twitch

Because of the Paypal restrictions... if businnes will keep to be good I'll turn the button 'Donation' to 'Buy' (a Paypal upgrade is required, with a fixed price for month). I hope so, I would get rid of preparing the packages manually.

OK, I guess that makes sense, although if others don't know the reason, they'll probably think you're playing word games. Anyway, good luck with your book.

Goi opening book version 5:

This new release includes a new way to make the book: for the first time I didn't only make and select powerful games through very powerful servers, but I also use them in analysis to correct some wrong/weak line. The result is impressing, as you may see in the benchmark subsection.

I have to admit that wasn't an easy work both because of the strength of my opponents and for a strange instability of the engines in selecting moves in deep search: the most of the times I came back with the lines and they gave totally different moves, but after a while going forth and back I've always found the point in which the score was in my favour, so I was able to correct all the mistakes in the lines and I've even discovered that there were weak lines also in the Cerebellum book. Streethawk07 gave me the idea, sending back some wrong lines of the past versions. After having passed all the tests, Playchess 2500 ELO engines room score included, I've decided to release the book.

For the first time I've introduced Raubfisch both in the making process and in the deep analysis of the variants, seen its latest strong enhancement that places it at the first place as top strongest chess engine. I'd be glad to host it on my website so that anyone can enjoy for free this incredible chess engine (little note for the great authors Frank Karl Werner and Max Fehler).

The programs used to make Goi 5 are: asmFish, BrainFish, CFish, Raubfisch and Stockfish 9 on both very powerful high-end rented servers and my computer.

Usually the variants have 50-80 plies in depth (so 25-50 moves White + Black). With Goi 5 you can reach a very advanced state of the game with a great position, even if you don't have a machine with a powerful processor. It's lines go from the very beginning until sometimes the ending of the game.

- Goi 5 BIN contains 8.770.285 positions (size: 133 MB)

The BIN distribution can be used with the Chessbase softwares with the following engines: Komodo, Houdini, Brainfish, CFish, asmFish, Raubfisch, Eman, Toltec, SugaR XPrO. It can be used also in Arena with (I guess) the same engines. It works also on Android with Droidfish.

Goi 6 Opening Book by Massimiliano Goi

Goi 6 opening book

This is an innovative book.

After the hard defeat on the last SCCT tournament, and seeing through it, I've decided to completely change the way in which I produce the Goi book.
Cerebellum lines are by now obsolete so I've decided to get rid of them. The previous Goi book wasn't a merging of Cerebellum + minibook, it was the product of a dissected Cerebellum (BIN to PGN) then reassembled, reordered and selected in some criteria, hence not a mere Cerebellum clone as someone accused...

With the upcoming of Attacker Pro and the growth of Vitamin in strength plus the Playchess best players private books I've realized the Goi 5 technique wasn't enough anymore to be on the top again. Goi 5.1 CTG was an experiment, I wanted to see how a book full of lines performed... it performed very bad at the SCCT tournament despite my huge dedication on it; it was a good book for Playchess, though. Anyway, the new 1.c4 killing lines on Playchess didn't permit Goi 5.1 to survive anymore, so I've decided to restart everything from scratch again and create a totally new book, hence the new version 6.

All these years of bookmaking and testing brought me to realize that the game is decided since the very first moves, as the engines have almost the same strength. Or better, a good book can allow you to win or at worst to not be beaten. The idea of a light book with incredibly powerful lines came into my mind then.

My vision wasn't wrong: during the time of betatesting Goi 6 got rid time after time of any other opponent.

I had in mind to select the games of the best players 1-0, 0-1 and create a base matrix, in which to lay down any other powerful game I selected.

Try to image my book like an onion: it's composed by a multitude of layers, first the top won games, then the top draw games, then my top players kibitzed games, then the engine tournament games > 2500, then my played games with the prototypes, then again kibitzed games, then again other engine tournament games > 2500, and so on. Create a new mini-book and merge it with the base prototype, then modify the lines where the errors lie. This for something like more than one hundred times. It was amazing but it required times, as you may have noticed. Many lines used by best players were improvable or even wrong, and this was inherited in my first beta version, so I had to manually correct them and test them myself both in books tournament and in the battlefield.

I had the idea to start a betatesting made not only by me, having few time, but anyone wanting to help me... Clearly I couldn't allow the book to leak out so easily (otherwise all my efforts would have been vane), so I decided to set up a reduced price for the betatesters to try it.

This testing thing didn't work, though, as people just "bought the book" without giving me almost any feedback or lost game, exception made for my partner Deiby L., which I thank so much. He sent me hundreds games played by his AMD ThreadRipper 2990WX from both Playchess gaming and private tournaments with other books.

I then tuned the CTG book with wins and losses and corrected the lost games using Cfish or asmfish on my dear night hawk machine on the Fritz Cloud room (or ducu7, but mostly night hawk).

This time the fun was great because by now I have fully grasped the mastery of chess bookmaking, so it was easy for me to correct any flaw I encountered and accentuate the lines in which my book was beating the other players/books.

Last but not least, since the stupid Fritz bug to play sometimes moves outside the book and making lose the game, I had to use an unconventional (and syntactically wrong) way to mark the moves on the lines I have analyzed (!green -> move to do, ?!red -> any other move to not do). For this reason Goi 6 is not a book for study, be CTG or BIN, this is just a book for competitions.

The fact that I forced the moves allowed me to vary the book parameters: variety of play is not anymore the minimum, but 70. In this way I got rid of infinitely drawing against Vitamin. Learning strength is different now too, 500 (the maximum), in the hope the book can learn from its evencutal losses.

I recommend you to NOT use Houdini, Komodo or Lc0 with this book as they are very weak compared to the Stockfish clones, unless you have a very, very powerful hardware and Lc0. The recommended engines for rapid games and average-high end CPUs are asmfish, Eman, Brainfish, Stockfish, Stockfish Polyglot and so on. I guess Goi 6 will have great result also with Cfish, CF_EXT, CorChess, McCain.

SX_Pro is suffering from some serious bug these times, so I wouldn't recommend it.

Thanks to:

Exxon, Leonidas, Sarissa, SASSY_MUFFIN, Ivers and Stables for having indirectly given me the material for the base matrix.

The MZChess forum for having constantly provided Playchess and Infinitychess tournaments.

Deiby L. for sending me hundreds of played games.

night hawk for renting his 80 threads beast for critical lines correction, a very beautiful engine.

My loyal customers.

Anyone who funded this project.
