This article is from the GNU Chess and XBoard FAQ, by Tim Mann firstname.lastname@example.org with numerous contributions by others.
As a shortcut to most things mentioned in this FAQ, try my Chess Web
page, http://www.research.digital.com/SRC/personal/Tim_Mann/chess.html .
My Web page is the best place to get the latest versions of XBoard and
WinBoard and the most up-to-date version of this FAQ.
For general news and information about chess, try the newsgroup
hierarchy rec.games.chess.*, especially the groups rec.games.chess.misc
and rec.games.chess.computer. Both of the latter groups have very
informative FAQs maintained by Steve Pribut; look for them on the
newsgroups or at http://www.clark.net/pub/pribut/chess.html .
Like other GNU software, you can get GNU Chess, XBoard, and WinBoard by
anonymous FTP from ftp://ftp.gnu.org/pub/gnu/ and its many mirror sites.
Look in the subdirectories gnuchess, xboard, and winboard. The .tar.gz
suffix on the files there indicates they were packed with tar and
compressed with gzip. The .exe or .zip suffixes indicate files that were
packed and compressed with zip.
For other chess software, try the Internet Chess Library. Use anonymous
FTP to connect to ftp.freechess.org, or go to the Web page
http://www.freechess.org/ . You can get chess software, game
collections, the FAQ file for rec.games.chess, and other chess-related
material there, in the directory pub/chess. The FTP server can
automatically decompress files for you as you download them, useful if
you don't have gzip.
Here is a sample anonymous ftp session. Some of the ftp server's
responses are abbreviated, but all the commands you must type are
