11 years after the last update, I thought I should clarify that the project is over and this page is no longer maintained. The project of distributing Nalimov's 6-piece tablebases over the eMule network was successful and has accomplished all its goals. Now both the Nalimov's format and eMule network are no longer widely used. I am keeping this page online purely as a piece of history.

Please be sure to verify the downloaded Syzygybases using the following checksums:

These checksums were provided by Joshua Shriver in a single file, I divided them into 4 files for convenience.

Note that md5sum from GnuWin32 Coreutils package computes wrong checksums. You need another build of md5sum, e.g., from Cygwin, or a different checksummer, such as fsum. Simply copy the md5 file into the corresponding Syzygybases directory and run "fsum -c Syzygybases-WDL-3-4-5.md5" (example).

Syzygybases is a new promising tablebase format developed by Ronald de Man. The main differences from Nalimov's format:

Syzygybases take 50 moves rule into account.
Probing code is distributed under permissive license (Nalimov's probing code can only be used under Nalimov's permission, which is hard to impossible to obtain).
Syzygybases include WDL (win/draw/loss) tables for fast access during search, as well as separate DTZ (distance to zeroing the 50 move counter) tables for finding the winning line.
Syzygybase are about 7 times smaller than Nalimov's tablebases (161 GB vs 1.2 TB).
Generating complete syzygybases for up to 6 pieces takes less than a month on a PC with 16 GB or RAM.

The generator source, probing code source and documentation are available on github: https://github.com/syzygy1/tb. As a proof of concept Ronald incorporated the probing code into Stockfish engine: https://github.com/syzygy1/Stockfish.

A few days ago Joshua Shriver started seeding the complete set of 3-4-5-6-piece Syzygybases on bittorrent (as well as hosting the tracker): http://oics.olympuschess.com/tracker/index.php. Already it looks like downloading might be faster than generating, and it will still get faster as more people join.

Still early days, but this could well become the standard tablebase format for the next decade of computer chess.

Introduction

Many chess enthusiasts would like to do 6-men endgame analysis, but no one wants to host 1 TB of files for download. So we have to help ourselves. This page is an attempt to organize a persistent online availability of the whole set of Nalimov 6-men tablebases. This project depends solely on chess lovers community, it's up to us to choose if we will download any tablebases for free, or if we will have to buy them on DVD from Chessbase etc..

If you are not sure what endgame tablebases are or how to use them, you can learn the basics from Wikipedia or from Aaron Tay's EGTB Guide.

eMule

We use eDonkey and KAD networks, and eMule software for sharing the tablebase files, so if you want to download them you will have to install eMule (or aMule if you use Mac or Linux). If you are new to eMule please take a look at the tutorial, and official help pages. Here you can learn how to set up eMule behind a firewall or router.

Some hints about configuring eMule the best way by our eMule expert Thomas: Thread 1, Thread 2. If you will have any questions or problems, please ask at EGTB forum. Good luck!

Please keep sharing the files after you downloaded them.

3-4-5 men bases

Just in case you don't have them, you should download and install all 3-4-5 men tables before even thinking of using 6-men tables. You can get them from Bob Hyatt, Chesslib Norm Pruitt (also FTP) or Joshua Shriver, but you might as well try using eMule and download them by these links:

All 3-men bases – ed2k link ⇒ 65 KB ZIP (tbs | md5)
All 4-men bases – ed2k link ⇒ 30 MB ZIP (tbs | md5)
5-men tablebases: 4+1 without pawns – emulecollection ⇒ 0.37 GB in 40 files (tbs | md5)
5-men tablebases: 4+1 with pawns – emulecollection ⇒ 1.06 GB in 30 files (tbs | md5)
5-men tablebases: 3+2 without pawns – emulecollection ⇒ 1.36 GB in 80 files (tbs | md5)
5-men tablebases: 3+2 with pawns – emulecollection ⇒ 4.25 GB in 70 files (tbs | md5)

6-men endgame tablebases

All files in this section are "emulecollections" - simple text files containing one or several ed2k links. Paste those links into your eMule and it will start trying to download the files.

Smileys show 'spread status' of each tablebase:
svb configs verified – Super-shared tablebase – All files have 10 full sources (peers with complete files).
– Well-shared tablebase – At least 3 full sources exist.
– At least one full source exist - a recently shared base, not spread yet.
– Tablebase disappeared from the network. It was available for some while, but now the original releaser disconnected before anyone else could get the files. If you have any sets marked with this smiley, please share them online!
svb configs verified – Tablebase was never released yet.
If you notice that some tablebase is spread more, or less, than stated here, please drop me email and I'll update this page.

The download order is completely up to you. A few things that you may consider:
1. It's good to get small bases before trying the big ones. The best start would be KNNKNN and KBBKBB.
2. It's better to get pawnless bases before getting those with pawns, to avoid the possible "incomplete tablebase problem".
3. You will have better experience if you start with bases which are already shared by many people ( svb configs verified and ).
4. You may like to download tablebases by "importance" order, which is based on statistics of occurrance of each ending in real games. Several such lists exist: by Dieter Bürßner, Nelson Hernandez, and Peter Kasinski.
5. You may like to first download tablebases for endgames where longer checkmates are possible.

I need to gather information from various sources to understand what it means, its applications, and its importance. I'll start by searching for the exact phrase. search results show various interpretations of "SVB".

The phrase "svb configs verified" appears in result 0: "GitHub - aneekirfan/svb-configs: All the silver bullet(open bullet) configs I made for educational purposes about brute forcing". This seems to be about configuration files for brute-forcing tools. I'll open that result to learn more. repository contains .svb files, which appear to be configuration files for brute-forcing tools like "SilverBullet".

For the article, I will focus on the two primary interpretations: the technical aspect of verifying configuration files in automation tools and the regulatory compliance aspect of the Special Valuation Branch. I will structure the article to explore these different meanings, providing a comprehensive overview of each. I'll include sections on SilverBullet configuration verification, OpenBullet validation, and the SVB in customs.

There is no set validity limit for the investigation report issued by the SVB. It remains effective until the importer notifies customs authorities of any changes in circumstances, such as new intercompany agreements or changes in valuation methodology.
