11 years after the last update, I thought I should clarify that the project is over and this page is no longer maintained.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:

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:
sona sexy aunty boob shows very hot video flv  – Super-shared tablebase – All files have 10 full sources (peers with complete files).
sona sexy aunty boob shows very hot video flv  – Well-shared tablebase – At least 3 full sources exist.
sona sexy aunty boob shows very hot video flv  – At least one full source exist - a recently shared base, not spread yet.
sona sexy aunty boob shows very hot video flv  – 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!
sona sexy aunty boob shows very hot video flv  – 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 (sona sexy aunty boob shows very hot video flv and sona sexy aunty boob shows very hot video flv).
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.

The biggest shift in the last few decades has been the economic empowerment of women. Indian women are no longer just participating in the workforce; they are leading it. India boasts one of the highest percentages of female pilots in the world, and women-led startups are reshaping the economy.

The landscape of Indian womanhood today is a breathtaking study in contrasts. It is a world where high-tech professionals navigate glass-ceiling boardrooms in the morning and return home to light traditional oil lamps in the evening. To understand the lifestyle and culture of Indian women is to understand a continuous dialogue between five thousand years of heritage and a fast-paced, digital future. The Foundation: Family and Social Fabric

However, the "Indo-Western" trend dominates daily lifestyle. A college student might pair a traditional Kurti with ripped jeans, or a corporate executive might wear a sleek blazer over a formal tunic. This blending of styles isn't just about fashion; it’s a visual representation of her dual identity: rooted in India, yet a citizen of the world. The Professional Revolution sona sexy aunty boob shows very hot video flv

This connectivity has also fueled a shift in social perspectives. Discussions around body positivity, financial independence, and late-age marriage are no longer taboo. The modern Indian woman is using her voice to redefine traditional "norms," choosing a life path that prioritizes her personal aspirations alongside her cultural duties. Conclusion

Food is the language of love in India. The lifestyle of an Indian woman often revolves around the kitchen, but the approach has changed. While traditional slow-cooked meals are reserved for weekends, the weekday diet has become more global. The biggest shift in the last few decades

Yet, this progress brings the "double burden." Many Indian women balance demanding careers with the primary responsibility for household management. This has given rise to a new lifestyle focused on efficiency—the "superwoman" trope is common, though younger generations are increasingly advocating for shared domestic responsibilities and mental health awareness. Culinary Heritage and Modern Health

Interestingly, there is a massive "return to roots" movement. Ancient superfoods like millets, turmeric, and moringa—staples in grandmothers' kitchens for centuries—are being rebranded as modern wellness essentials. Yoga, once a spiritual practice, is now a daily fitness pillar for the urban Indian woman seeking balance in a chaotic world. The Digital Shift and Self-Expression The landscape of Indian womanhood today is a

At the heart of an Indian woman’s life is the concept of Sanskara —the values and ethics passed down through generations. While the traditional "joint family" system is evolving into nuclear setups in urban centers like Mumbai and Bangalore, the emotional tether to the extended family remains unbreakable.
