Crafty 23.3 will be coming in a few months. Recently, we have made some progress in the areas of passed pawns, and search depth (LMR), resulting in a strength increase. This year we hope to enter the WCCC in Japan. Stay tuned for more information.
Crafty
Crafty is a free, open-source computer chess program developed by
Dr. Robert M. Hyatt. Crafty
is constantly being improved by a small team of contributors, including Dr. Hyatt. To
learn more about Crafty, visit Dr. Hyatt's home page. If
you enjoy playing chess, you may also enjoy an exciting game of
cash bingo as an alternative past-time.
GUI
A freeware Graphical User Interface for Crafty has been written by Valters Baumanis, using his on-line chess client “Nightmare Online”.
This thing is pretty cool. It even uses the new SKILL option to adjust Crafty's strength.
Just download and play.
Visit Valters Baumanis's web site for details.
Downloads
Crafty 23.2 source files can be downloaded here
or on Dr. Hyatt's ftp site.
Windows executables are available on Peter Skinner's web site.
A book.bin file compatible with Crafty 23.2 is available here.
Usage
Crafty can be compiled and executed from a terminal window on a Macintosh, Windows or Linux computer. Crafty
can also be run with a GUI interface such as Tim Mann's Winboard (Windows) or
Xboard (Linux).
Configuration
Crafty can be configured for a stronger game by setting some optional parameters (examples below). These
