I can't find where you can download endgame tablebases from http://kd.lab.nig.ac.jp/chess/tablebases-online/ The links with the pieces, tbs, and MD5 don't seem to do it. Can someone point me to where they can be downloaded? -- Replace you know what by j to email

I'm on a fairly slow DSL connection, for which the automatic configuration found 96 KB/s DL rate (which leaves me some bandwidth for non-downloading). I have an average download rate of 55 KB/s counted over something like 100 days of use. KBNNKR is 156 + 531 MB (these are quite small for six-piece EGTB). Some engines allow you to use only one of the two files, so you may be able to get it faster. -- Anders Thulin anders*thulin.name http://www.anders.thulin.name/

On the site just below the "Introduction" heading tells of this. If you can handle just using the 5 man tablebases you can get them fro Robert Hyatt's site- ftp://ftp.cis.uab.edu/pub/hyatt/TB/ click on the '3-4-5' folde -- cbseries

Later I did find out about eMule and I installed that. However, when I got a download to start, it was going at slower than dialup speed, so it was going to take several days to download just the files for one ending. I stopped that one and tried a few other servers, and none of them would even start. They would just say "waiting". Is there a server that works and works at broadband speed? -- Replace you know what by j to email

You download a chunk at a time, after which the peer puts you back in its queue. How quickly you reach the front again is anyone's guess. There are a few systems that seem to give you all they have for as long as it takes, but typically it takes perhaps a week to get a file. Of course, the thing is that if you place say 15-20 files in your request queue, it still will take about a week to get them all (assuming they're frequent files, and available from many eMule systems). Rare files will come at a speed entirely depending on the few systems that share them. You can improve things by ensuring that you do not have a low ID problem -- that tends to downrate you, as you then don't talk directly to your peer. And you can also improve things by sharing your downloaded files -- that, too, will increase your status. Look through the Thread1 and Thread2 references on the web page for recommendations. On the other hand, downloads tend to be faultless, and if there are problems, they're isolated to small segments which are then downloaded again automatically. With less capable methods, you often have to redo from the top. If you have to use FTP or HTTP, there are some links in the 'Additional information' section that you may want to check out. -- Anders Thulin anders*thulin.name http://www.anders.thulin.name/

A very rough guess, based on how long it took to generate 5-piece endgame tables on a much slower machine is something on the order of three or four days. -- Anders Thulin anders*thulin.name http://www.anders.thulin.name/

Any idea as to how many moves are involved, for the six-piece endgames? DSH "Jud McCranie" <[email protected] > wrote in message news:[email protected]... > On Sun, 17 Jun 2007 22:34:59 +0100, "D.

D. Spencer Hines <[email protected] > wrote: > Any idea as to how many moves are involved, for the six-piece > endgames? Tablebases store positions, not moves. For each position, the tablebase stores the number of moves until the win or loss or the fact that the position is drawn. Given a position, you consider each legal move and ask the tablebase for the evaluation of the resulting position. If any of them are wins, you make the move that leads to the shortest win; otherwise, you make any move that leads to a draw; otherwise, it doesn't really matter what you do because everything loses. As for the question of how many positions are involved for a six-piece endgame, I'm afraid I don't know. However, they presumably don't store distances to wins of greater than 50 moves, so seven bits per position should suffice. So, dividing the size of the file by 7/8 should give a reasonable approximation.
