I've seen many more off-topic questions than that in this forum! :-) I know why you're asking, but so far I'm afraid I have to disappoint you: My program is currently in C (although some small parts of the C code and data were written by Lisp programs). It is not a new program, but a resurrection of the program I worked on several years ago. At that time, I gave up in frustration because the program was so slow and buggy, but recently I found out that modern hardware is fast enough that the program plays OK despite all the bugs. :-) At the moment, portability has the highest priority for me. I develop the program on a Mac, it plays on the ICC running on a Linux machine, and several brave and friendly beta testers use it in Windows. Therefore, gcc is my compiler of choice. I still hope to find the time to rewrite the program in Macintosh Common Lisp with inline assembly language to elimitate bottlenecks, but I am not sure when that will happen. Obviously, I will then have to sacrifice easy portability (at the moment I use precisely the same source code for all three platforms, there are not even any platform-specific #defines in the code). Right now, I have so much fun watching the games my program plays in various tournaments for Winboard engines that I don't want to limit myself to the Macintosh platform. Tord
