goi4

 

 

 

By now my book has no need anymore to any presentation: the strongest chess opening book you can find on the market. Since the constant increasing demand, a minor update has been released. All those who have purchased the 4.3 version will be upgraded for free in the next 24 hours.

Built using only Stockfish 9, CFish and asmFish on very powerful high-end rented servers, Goi 4.3 contains 10604917 positions (1 milion has been added since 4.2), from the very beginning until sometimes the ending of the game. In average you will reach 30-40 moves from the start (that is 60-80 plies).

Supported engines: Komodo, Houdini, Brainfish, CFish, asmFish, Raubfisch, Toltec, SugaR XPrO. It works also on Android with Droidfish.

Goi opening books collection package: size 1.66 GB, price 50$.

 

Sincerely I don't see the point of this, but since someone's asking me this, there you go:

What you'll get with this package

---------------------------------------

Annual subscription: price 60$.

 

With this option you will get updates for a whole entire year starting by the day you make the payment. I make in average two products per month (BIN and CTG) at the average price of 10$ for each, so it would be 10$ x 2 x 12 months = 240$, that's a big saving! Anyway I warmly advice to get this option after you have tried a few times my books and you're satisfied with.

How to install the BIN format on Chessbase softwares:

 

binbooksinstallation.jpg


Tick 'OwnBook' and enter the full path of the file followed by its name plus its extension.
As example: the bin file is in the folder C:\Users\Bob\Documents\ChessBase\Books → you will have to enter the string C:\Users\Bob\Documents\ChessBase\Books\goi3.2.bin

Set the maximum possible of 'BookDepth' (if I recall correctly asmFish has 100, while Brainfish 255).

 

 

How to install the BIN format on the Arena GUI interface:


 

 

 

 

How to install the CTG format on Chessbase softwares:

 

Place the goi3.2.ctb, goi3.2.ctg and goi3.2.cto files into the same directory, then start your Chessbase program, such as Fritz and use what listed below on the 'Advanced' settings of the engine:

- Tick the Tournament book box

Chess engines:

 

 

What is the 2018 strongest chess engine? May tournament.


 

I have made an individual tournament between the most powerful engines to see which is the strongest, so that you can always have here the best engines for free. It's something I make periodically, wheter with video on YouTube or not.

The 1 minutes tournament has brought two leader with a very slightly difference compared to the other engines: BrainFish and asmFish. BOTH CFISH AND S_XPRO WERE OPTIMIZED (compiled from source for this computer).

 

 

The settings were: 2 thread for each engine, 256 MB of hash table, Goi 4.3.1 CTG opening book, 6 pieces Syzygy.

Settings (shared) of the opening book: Tournament book: ticked, Minimum games: 3, Up to move: 35, Variety of play: 50, Influence of learn value: 100, Learning strength: 500.

 

Download here the archive of the games in Chessbase and PGN format.

 

-----------------------------------------

 

The 3 minutes tournament has brought the same two winners, this time in opposite order, with half point of difference. Since in these two matches asmFish and Brainfish reached alternatively the first place, I declare them the winners and the strongest engines available at the moment. Since BrainFish is the most updated, I advice anyone to download it instead of asmFish.

 

 

The settings were: 2 thread for each engine, 512 MB of hash table, Goi 4.3.1 CTG opening book, 6 pieces Syzygy.

Settings (shared) of the opening book: Tournament book: ticked, Minimum games: 3, Up to move: 35, Variety of play: 50, Influence of learn value: 100, Learning strength: 500.

asmFish: Updated May, 15 2018

 

Based on a work of Mohammed Li, it was continued by Lyudmil Antonov. Includes: armfish, that is asmFish for Android (only 64 bit Androids, unluckily, so the newest ones), asmFish base version for standard CPUs, and the program mateFish. Supported platforms (all 64 bit): Windows, Linux, MacOS, Android. The standard version should work on 32-bit system too. Someone would be so kind to let me know it? Write me in the Contacts section.

 

asmfish

 

Go to the Lyudmil Antonov's GitHub page to find all the executables.

 

 

 

BrainFish: Updated May, 17 2018

 

Brainfish is a standard Stockfish chess engine extended by the general polyglot book format. There are some extensions in the Book Code for handling repetitions. In BrainFish the Book moves are only used in engine games, not in analysis mode. That means when BrainFish is playing moves which are in the Cerebellum book, it plays like StockFish regarding the evaluation, only at a much higher skill level. Pondering is only active after the last move out of the book has been played.

 

You will need a software like 7Zip or WinRAR to extract the archive.

Stockfish 9: Updated February, 18 2018

 

The official Stockfish 9 releases. Versions for Windows (32bit, 64bit, modern computers, Haswell CPUs also known as BMI2) and Linux (64bit, modern computers and Haswell CPUs), MacOS and Android (32bit, 64bit).

Droidfish:

 

If you want to get the best app for your Android smartphone/tablet you must download Droidfish, by Peter Österlund. This app combines the strength of the new Stockfish 9 with the ease of use of a handling device. You can play against a Grand Master laying down on your couch or sit on your train place. With the Analyze mode you can also check your games and see where you made a mistake.

 

Download it on Google Play Store

 

You can also buy my opening book to get extreme performances, as long as installing the 3-4-5 pieces Syzygy tablebases.

 

 

 

Syzygy tablebases for ending games:

 

Syzygy tablebases are the latest and most reliable resource to enhance the speed and the computing precision of the endgames. In order to use them you must have a recent Chessbase chess program, the Droidfish app for android pr the free Arena GUI.
These databases are subdivided in two parts: the Syzygy for game endings up to 5 pieces, sized circa 1 GB, and the Syzygy for 6 pieces, subdivided in WDL (the main part, size 68.3 GB) and DTZ (checking the 50 moves rule, size 81.9 GB); total 150 GB.
EVERY tablebases, whether is the 3-4-5 pieces or the 6 pieces, must be run on a VERY FAST storage, like an SSD drive or an USB pen. The essential one is the 3-4-5 pieces database, so you can just buy an USB pen if you don't want or can't spend money to buy an expensive device like an SSD drive.
The fundamental part, both for mobiles and PCS is the 3-4-5 archive (direct link below), because of its relative light size it can be hosted on a clouding storage or even a website. Different facts are for the 6 MAN Syzygy (6 MAN = 6 pieces DTZ + WDL), being sized 150 GB you must download it by installing a torrent client (be aware of the unwanted programs they are asking at the installation process). The one I feel to suggest is Bittorrent.

 

Download: 3-4-5 pieces. <- Direct link

NO DIRECT LINKING FROM OTHER WEBSITES TO MY CLOUD IS ALLOWED.

 

Download: 6 pieces (extract the torrent files from the zip archive then use a torrent software to download the tablebases).

Arena free chessboard:

 

 

 

Want to get a FREE chessboard after having downloaded a FREE, powerful chess engine above? Download Arena, it comes also with its own engines (weaker than asmFish, naturally), its own opening book (weaker than mine but good) and its own endings database. It's a marvellous complete tool for anyone wanting to play and study chess without to spend a coin. You can also use asmFish with it, of course. Multiplatform, for Windows and Linux.
In order to get this beautiful software you have to go on their website, link below.
