Rest In Peace Bobby
Crafty 22.1 is now available!
This release includes some minor bug fixes, a small time control change for very short games, and some tweaks for more compatible compiling. A new SKILL option is now available to reduce Crafty's strength (so people like me can win too).
(Refer to main.c comments for copiling and usage of the SKILL option.)
Crafty
Crafty is an 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.
GUI (NEW)
A freeware Graphical User Interface for Crafty has been written by Valters Baumanis, using his online 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 22.1 source files can be downloaded here
or on Dr. Hyatt's ftp site.
Windows executables are available on Peter Skinner's web site.
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
parameters can be put into the crafty.rc file, or used as startup parameters from the terminal. A
more thorough explanations of Crafty's parameters can be found here.
