Goi opening book version 5:

 

 

Goi 5 chess opening book

 

 

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.

 

- 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, Toltec, SugaR XPrO. It can be used also in Arena with (I guess) the same engines. It works also on Android with Droidfish. You will find below the instructions on how to use a Polyglot book (BIN) with the mentioned engines.
