OpenChess

After resisting the temptation for years, I spent several weeks this summer writing a chess program. The program's name is Kirby, and at the moment it's nothing more than a (very slow) move generator, a basic alpha-beta search and a (very crude) evaluation. But it plays legal chess, albeit quite slowly and very badly. (See below for a crushing loss to Crafty-23.3!)

I decided to start from scratch---for example, I use a 12x12 array for board representation ---and it has been a blast. Not sure if/when I'll have time to do more, but I've really enjoyed the project so far. And it's nice to know that I won't be seeing any polls asking who thinks Kirby is a clone/derivative!

This is great news!

I'm guessing that Kirby is Winboard compatible? Is it an there an official release or is it still private?

Is the name based on the Nintendo character?

Looks nice

Feel free to enter next cycle of ChessWar that will start in September.

No support yet for any gui. And certainly not ready for release!

Not familiar with the Nintendo Kirby. Actually, the program is named after my recently deceased cat, who was named after Kirby Drive in Houston, Texas (which apparently was named after John Henry Kirby).

I see, I'm sorry for your cat, I've had more than 24 cats in my life and one gets so attached to them that when they die is a great pain.

Anyway, Nintendo Kirby is the most famous Kirby as can be seen when searching for Kirby images on Google, sorry for the confusion, and good luck with your engine.
