Chessking endgame tablebase update#

If you notice that some tablebase is spread more, or less, than stated here, please drop me email and I'll update this page. If you have any sets marked with this smiley, please share them online! It was available for some while, but now the original releaser disconnected before anyone else could get the files. РІР‚вЂњ Tablebase disappeared from the network.

Chessking endgame tablebase full#

РІР‚вЂњ At least one full source exist - a recently shared base, not spread yet. РІР‚вЂњ Well-shared tablebase РІР‚вЂњ At least 3 full sources exist. РІР‚вЂњ Super-shared tablebase РІР‚вЂњ All files have 10 full sources (peers with complete files). Smileys show 'spread status' of each tablebase: Paste those links into your eMule and it will start trying to download the files. 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:Р”Р„ll files in this section are 'emulecollections' - simple text files containing one or several ed2k links.

Chessking endgame tablebase install#

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. Please keep sharing the files after you downloaded them. If you will have any questions or problems, please ask at EGTB forum. Some hints about configuring eMule the best way by our eMule expert Thomas: Thread 1, Thread 2.

Here you can learn how to set up eMule behind a firewall or router.

If you are new to eMule please take a look at the tutorial, and official help pages.

Chessking endgame tablebase software#

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 not sure what endgame tablebases are or how to use them, you can learn the basics from Wikipediaor from Aaron Tay's EGTB Guide. 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. Many chess enthusiasts would like to do 6-men endgame analysis, but no one wants to host 1 TB of files for download. Thanks to Eugene Nalimov, Andrew Kadatch, Robert Hyatt, Kyrill Kryukov, Nelson HernandezР’В for generating, compressing, and publishing the databases and offering them for free. Thanks to community support, the whole collection is now freely available online on eD2K/KAD network. In August 2006 the last 6-men tablebases were computed, completing the 3-to-6-men tablebase collection of about 1.2 Terabytes. At the same time Nalimov was continuing to release new 6-men tablebases that were now shared via this project. Many people joined contributing files they managed to save.

In November 2005 several enthusiasts started a project to find and share all surviving tablebases. The only way to get them was by personal communication with other chess fans. 6-men tablebases were removed from FTP and disappeared from online space. Gradually Nalimov was releasing more and more gigabytes of 6-men tablebases and at some point Bob's FTP could not handle the load.

Historically Nalimov Tablebases were computed by Eugene Nalimov and distributed by Robert Hyatt via FTP. They provide a powerful analytical tool.Р”В®ndgame tablebases for other board games like checkers, chess variants Р’В or Nine Men's Morris Р’В exist, but without a specific mention of the game, one is talking about chess. Tablebases have enhanced competitive play and facilitated the composition of endgame studies. Some positions which humans had analyzed as draws were proved to be winnable the tablebase analysis could find a mate in more than a hundred moves, far beyond the horizonР’В of humans, and beyond the capability of a computer during play. The solutions have profoundly advanced the chess community's understanding of endgame theory. Tablebases have solved chess for every position with six or fewer pieces (including the two kings). Tablebases are generated by retrograde analysis, working backwards from a checkmatedР’В position. Typically the database records each possible position with certain piecesР’В remaining on the board, and the best moves with WhiteР’В to move and with Black to move. Thus, the tablebase acts as an oracle, always providing the optimal moves.

The tablebase contains the game-theoreticalР’В value (win, loss, or draw) of each possible move in each possible position, and how many moves it would take to achieve that result with perfect play. It is typically used by a computer chess engine during play, or by a human or computer that is retrospectively analysing a game that has already been played. An endgame tablebaseР’В is a computerized databaseР’В that contains precalculated exhaustive analysis of a chess endgameР’В position.
