I'm mainly interested in the science of comparing results (and the nature of the games) vs each other. What you have explained is politics. If there were a way around these "politics", I'd be very interested if both Shredders could be in. e.g. There only needs to be a prize for one of them, i.e. 9. It's not much interest to me which one wins. I'm not sure if it IS that interesting to most intelligent people. It will probably be Shredder, anyway. But if you combine it with the right selection for most interesting testing, then I'm not complaining about other aspects, like WHO wins. Maybe the only interest in computer championships, is for the programmer, as well as for non intelligent audiences who are potential consummers, to the delight of the programmer. S.Taylor
