Goi opening book version 5:



Goi 5 chess opening book





Goi 5 GOLD:


This particular feature is not for sale and it's only available for subscribers as a free update and it represents a gift to those who have shown trust and spent some money more in advance to get my books for some month, or even a whole year. In addition I will give this special book to some loyal customer who has bought my books very frequently. I've spent too for this book, making orders above 100 dollars on my chess server provider (yes, as someone pointed out it was 80 threads, not 80 cores. A Dual Xeon E7 with 80 threads...).

The book is a polyglot (.bin) one and is sized 198 megabytes. There won't be any ctg version of it.

It contains 13.002.903 positions. It was funny to see how it got rid of Vitamin 12 so quickly in several tests because of the huge amount of powered games I have bought. Of course a hand work in deep analysis was mandatory and has been made on many losing positions. You will find some trace of it in the Chessbase LiveBook.

I have just sent the book to Sedat Canbaz to participate to the continuation of the upcoming SCCT book championship, the subcribers and the special customers will get this gift as soon as the tournament is started again.

I repeat: this book is NOT for sale, so if you are not a subscriber the only way to get it is to make a subscriptions for my books (3, 6 months or annual).

Below you will find the match against the latest Cerebellum and Vitamin 12, in the further days other tests with top books will be published.


Click here for benchmarks. (Latest benchmark: September, 9 2018)


I am searching for a cerfitied Grand Master or FIDE Master to help me with the opening theory applied to my book. That figure will be able to give me suggestions on how I can get stronger lines by reading the games test lines. As a payback I promise money and the book, of course, totally free of charge. I won't accept players having ELO less than 2300 and persons not showing me a real FIDE certification! If you are interested you can write me in the Contacts section.


Goi 5 opening books:


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. Its lines go from the very beginning until sometimes the ending of the game.


Thanks for the precious help to: Black Queen, Zagor Almanah, coffeeone.
