Tablebases
How long until 8x8 chess is completely in tablebases? Is it too optimistic to say, it will be in the lifespan of our planet (that will die in 7.59 billion years as scientists found out)?
When do you think that castling will be implemented? For practical reasons it should be at no more than eight pieces (which occured once).
PS: Until then, you can find the ultimate tablebase at http://sh-kunstschach.eu/tb/tb.txt
(PPS: dear arabic / israeli people, please look "wrong" way, e.g. start at left top, not right top)

It works. 42 ist the ultimate answer.
Please refer to Douglas Adams (http://en.wikipedia.org/wiki/Answer_to_Life%2C_the_Universe%2C_and_Everything).

Geez, what a question!
Any dolphin or mice would know the answer by heart!
So long and thanks for all the fish! :o)

Siegfried, if we are to believe the people who now have generated a complete tablebase for checkers, your hope is indeed 'slightly' optimistic. Check http://chessbase.com/newsdetail.asp?newsid=3997 and the links there and calculate, if you're interested. I just did...

Wasn't there some formula like "every two years the speed of computers doubles" etc?

Well to go back to our field.
It seems that some teams began to work on tablebases for 7 men.
someone knows something about that ?

Jacques, I'll ask an expert when I make an interview with him (should be soon but takes longer than I thought).
Anyone has a fast internet connection? I'd like to be able to get around 1.2 Terabyte data soon (maybe even in 2008 or 2009). Or maybe I should buy those HDs with preentered tablebases.

The following links are very useful if you want to download tablebases (up to six men)or if you want informations about the 7-men tablebases:
http://kirr.homeunix.org/chess/tablebases-online/ (download with eMule)
http://kirr.homeunix.org/chess/discussion-board/viewforum.php?f=6 (EGTB forum)
http://www.vlasak.biz/tablebase.htm (file with the first 7-men results)
You don't need very fast internet connection to download the most important tablebases(like RPP/R, RP/RP, PP/PP,QP/QP, QPP/Q,...)in a few weeks.
You don't need to download all of the 1.2TB's of data. Endgames tablebases like QQQ/N or BBB/B aren't very useful.

I think, BBB/B is very useful. At least for a general examination if BB+b/B and BB+b/b are won (B and b being bishops on opposite colors). Ok, I would download it only because it can't be big. Else, 6 men online TB would be enough.
