11 years after the last update, I thought I should clarify that the project is over and this page is no longer maintained.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

Etika bisnis bukan sekadar rangkaian aturan formal atau pedoman kepatuhan; ia adalah nalar moral yang menyatukan nilai-nilai kemanusiaan dengan praktik ekonomi. Dalam konteks ini, karya-karya pengantar yang menempatkan etika sebagai fondasi berpikir bagi pelaku bisnis, mahasiswa, dan pembuat kebijakan memiliki peran strategis. Buku pengantar etika bisnis—seperti yang diasosiasikan dengan nama K. Bertens—berpotensi menjadi jembatan penting antara teori filsafat moral dan dinamika dunia usaha kontemporer di Indonesia. buku pengantar etika bisnis k bertens pdf
Akhirnya, aspek akademis dan etis harus berjalan beriringan dengan etika akses terhadap bahan bacaan itu sendiri. Dalam wacana pendidikan, ketersediaan sumber yang berkualitas, mudah dijangkau, dan diperoleh dengan cara yang menghormati hak cipta menjadi penting. Penggunaan versi PDF yang tersebar luas tanpa izin mengangkat pertanyaan legal dan etis tentang hak cipta serta kompensasi intelektual. Di saat yang sama, hambatan akses—biaya atau ketersediaan—membatasi penyebaran pengetahuan etika yang sangat dibutuhkan. Solusi yang berimbang adalah mendorong penerbitan terjangkau, lisensi pendidikan, dan inisiatif yang menjamin keseimbangan antara hak penulis dan kebutuhan publik akan pendidikan etika.

Namun, nilai sebuah buku pengantar juga tergantung pada cara penyajian. Gaya bahasa yang natural, struktur bab yang logis, dan contoh-contoh kontekstual membuat materi berat menjadi dapat diakses. Untuk pembaca Indonesia, relevansi lokal sangat penting: studi kasus yang mengangkat praktik bisnis di pasar domestik, budaya korporasi di nusantara, dan implikasi hukum serta norma sosial setempat meningkatkan daya guna buku. Pembahasan yang terlalu abstrak tanpa aplikasi praktis berisiko membuat pembaca akademis saja yang merasa diuntungkan, sementara praktisi butuh alat konkret untuk menerapkan etika dalam kebijakan perusahaan, pemasaran, atau rantai pasok. tanggung jawab pemangku kepentingan
Kesimpulannya, sebuah buku pengantar etika bisnis yang ideal—seperti yang diharapkan masyarakat akademis dan praktisi Indonesia dari karya yang dikaitkan dengan nama K. Bertens—harus mampu menyatukan kekuatan teori filsafat moral dengan contoh konkret, konteks lokal, dan isu-isu kontemporer. Lebih dari sekadar mengajarkan apa yang benar atau salah, buku tersebut harus memfasilitasi keterampilan berpikir etis: analisis kasus, refleksi nilai, dan implementasi kebijakan yang bertanggung jawab. Dengan begitu, ia dapat berkontribusi pada pembentukan ekosistem bisnis yang tidak sekadar mengejar keuntungan, tetapi juga menghargai keadilan, integritas, dan keberlanjutan.
Kekuatan yang paling menonjol dari buku pengantar etika bisnis ideal adalah kemampuannya menggabungkan kerangka filosofis klasik dengan kasus nyata yang relevan bagi pelaku bisnis modern. Pembaca membutuhkan penjelasan yang memadai tentang teori-teori utama—deontologi, utilitarianisme, etika kebajikan, kontrak sosial—serta panduan untuk menerjemahkan teori tersebut ke dalam keputusan sehari-hari: kebijakan perusahaan, tanggung jawab pemangku kepentingan, transparansi, dan tata kelola. Bila Bertens meramu isi semacam itu, manfaatnya besar: mahasiswa memperoleh dasar konseptual yang kuat; manajer mendapatkan alat refleksi etis; pembuat kebijakan dapat menimbang nilai-nilai bersama dalam regulasi ekonomi.
