I was browsing in CCRL Endgame Tablebases Forum, when I read this topic:

7 8 or more pieces tablebase generator

According to the author (Pedro Pérez Moreno), this tool (which reminds me to Freezer) was developped in the last four years. It can be downloaded for free from this URL:

http://www.mtu-media.com/finalgen

The web is well documented with a tutorial and some examples. The downloaded file is an installer, and once installed, FinalGen is translated into English, French and Spanish.

Note: "FinalGen is a chess endgame tablebase generator for Windows."

I did not see any indication that source was available, or that other operating systems were supported.

I have tested this new tool. It has some limitations but it is working fine.
I like the "Search for draw" option, here's an example (the only move that draws is 1.Ka1!!):

Thank for the link Jesús. Wold be nice to have a linux version, but we have to ask Pedro.

Sure some problems are out of reach, like the one with a black rook on g column to be cuadrangulated, also a corresponding squares problem.

Another step on the road to solving chess... ? :wink:

Hi,

Do you understand what the software is doing ?

Chess Software of the year. Maybe we should offer such a symbolic prize ...

Is the software free of malware? After installing, Panda Antivirus says virus: Trj/CI.A

And it tells it needs 2TB and 96 GB of disk space ?!
