Of course. Just ask for it

Beside GNU Chess for Macintosh, I also use Mac chess, which has quite a smart AI too. At least for me. Anyway, help yourself, GNU Chess is free, under GNU licence, though. But freeware anyway.
tip: the file is in sit format (Stuffit), but since this forum doesn't allow such format as enclosure, then I had to use a small trick. I renamed it as a zip file

Clever idea eh? Anyway once you downloaded it, just rename it in .sit and unstuff it. That's all.
