Endgame tablebases

Sort:
cavallo2014

I read on Wikipedia that now there are endgame tablebases up to 7 men, but I cannot find a way to access them online.

I found some tablebases on the Shredder site, but they are up to 6 men.

Does anyone know if there is a free site which allows to consult them?

If you read the Wikipedia entry carefully, it tells you where to get them.

Tablebases are generated by retrograde analysis, working backwards from a checkmated position. By 2005, all chess positions with up to six pieces (including the two kings) had been solved. By August 2012, tablebases had solved chess for every position with up to seven pieces (the positions with a lone king versus a king and five pieces were omitted because they were considered uninteresting).[1][2]

 

It didn't mention Shredder.

The Losomonov are only commercial, sold by ChessOK. Losomonov used a super-computer for making them. I just have a notebook.

The Shredder one can be found here freely, but they are only up to 6 men: http://www.shredderchess.com/online-chess/online-databases/endgame-database.html

I didn't find a link in Wikipedia to a free online site where I could input a position, and see the result up to 7 men.

You don't need a supercomputer. Yes, ChessOK aka Convekta did the work, rented the supercomputers, hired the programmers and all that they ask is that you buy one of their other reasonably priced products and you get use of the Table Bases for free in 2014.

from the paged linked in the Wikipedia entry:

All users of ChessOK AquariumHoudini Aquarium and Chess Assistant products get free access to the service for the period specified in their product description.

// See the word "free". It's free.
