I've written a chess program called "Deep BASIC" as a hobby and I'm looking to compare it to other chess programs written in BASIC. So far I have only found two programs that work, one called "New Proto Chess System" and another one that was written by a French person way back in 1984. I did find another chess program written in BASIC with nice graphics (for DOS BASIC), but when I started it up the opening move was h4 and then I couldn't move my own piece because the mouse cursor was invisible. So much for that. So it seems that the vast majority of chess programs written in BASIC play very poor chess. I have heard of one program called "Rabbit" which uses some assembler to improve speed but I cannot find this one. Does any one know where I can download it? As for my program, I estimate its strength to be around 1500, and it can only search 3000 NPS on my Athlon 650 which is about 4 ply in 20 seconds. It also has a 40,000 move opening book. If anybody is interested in it, I can make it available for download. Here is the game played against New Proto Chess System. This program seems very good at committing suicide even though the code is almost twice the size of mine.

It played surprisingly well considering the small size of the program.
