11 years after the last update, I thought I should clarify that the project is over and this page is no longer maintained.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:
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.
(Older news are archived here).
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.
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.
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 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:
– 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!
– 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
(
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.

While the phrase "old dog sex top" sounds like it might be a typo or a specific internet slang term, in the context of canine health and aging, it typically refers to in senior dogs or finding the best orthopedic beds (tops) for older dogs to rest comfortably.
As dogs enter their senior years (typically age 7 to 10 depending on the breed), their endocrine and reproductive systems undergo marked transitions. While younger dogs exhibit strong, clear reproductive cues, an older intact dog’s behavior can be far more unpredictable. Senior Male Reproductive Behaviors
Female dogs do not stop having heat cycles as they age. Unlike humans, they do not experience menopause. Their cycles may simply become more irregular, farther apart, or silent (showing no outward signs). 2. Recognize Common Health Risks
Senior dog storylines are inherently about redemption and second chances. When a narrative features a rescue dog finding a loving home—and subsequently helping their new owner find love—it reinforces a comforting universal truth: it is never too late to start over. It reminds the audience that your past does not define your capacity for future happiness. 3. A Sandbox for Processing Grief
It redefines the definition of "sexy." In mainstream media, romance is always about what bodies can do to each other. In Old Dog stories, romance is about what two people can endure together. The romantic climax might not be a wedding; it might be a scene where one partner holds the other’s hand during a chemotherapy session, or reads aloud because the other’s eyesight has failed. old dog sex top
In the world of romantic fiction, the "meet-cute" often involves a runaway puppy or a high-energy Golden Retriever Tangling its leash around a handsome stranger. However, a new trend is emerging in contemporary romance and literature: the "old dog." Writers are increasingly using senior canines to ground their romantic storylines, adding layers of emotional depth, vulnerability, and a sense of shared history that a younger animal simply cannot provide.
: Stories frequently focus on adopting a senior "soulmate" from a shelter. A common narrative arc involves an elderly person and a senior dog—both "two old souls" carrying loss—finding comfort and healing in one another.
Understanding why a senior dog suddenly begins mounting other animals, objects, or people requires looking past reproductive instincts and evaluating their overall health and mental well-being. Decoupling Mounting from Sexual Drive

Incorporating old dog relationships into romantic storylines does more than just tug at the heartstrings. It validates the reality of aging and the beauty of the twilight years. It tells the reader that love isn't just about the initial spark; it's about who stays by your side when the pace slows down. Whether in a cozy small-town romance or a sweeping dramatic epic, the senior dog remains one of the most poignant symbols of a love that is built to last. Share public link
What makes these storylines so compelling? It’s the slow burn. It’s the antithesis of instant gratification. An old dog doesn't fall in love; they are dragged into it, kicking and screaming (metaphorically speaking).
Sometimes, an older dog may exhibit an erection or mounting behavior simply due to overexcitement or an adrenaline rush. Simple pleasures like receiving a treat, being petted, or seeing a favorite family member return home can cause a surge of hormones and physiological responses. 3.

In romantic fiction, dogs are frequently used as "meet-cute" facilitators. While a rambunctious puppy might cause a chaotic collision in a park, an old dog fosters a different kind of connection—one built on empathy and shared values.
Decades passed, and Henry built a successful career, but he never forgot Emily. He often wondered what could have been if they had stayed together. One day, while browsing through old yearbooks, Henry stumbled upon Emily's name. He couldn't resist the urge to reach out, and to his surprise, she agreed to meet.
