that I am one of your customers. Good stuff...
CV BJ is a blast for tune-up prior to playing... CVCX can answer off-the-wall playing questions. Might consider making it a threaded program since new processors are going to start being dual-core within the next year or two (IE AMD opterons will be two cpus per chip early in 2005, intel has hyper-threading already and has dual-core on their roadmap, etc...)
My chess program is threaded and can scream on 2-4-8 cpu systems...
