Crafty UCI...

[jdart]

To my knowlege, Bob Hyatt never released Crafty under a permissive license, allowing modified versions to be released. It's his copyrighted code, and creating derivative works without his permission would be violating his copyright.

I’ve written to Bob and asked for his express permission. If he objects I’ll delete the repository. I also reached out on Facebook. I only have his university of Alabama email. If anyone has a more recent email please send via private message.
