Imagine programming for an OS where the filesystem uses 8.3 filenames, and you specify on the box that your program is meant to be used under that OS. Suddenly someone uses your thing in a place they aren't supposed to use it, and they have 256 character filenames, and you can't handle it and somehow a filename overwrites your piece-square table and your thing plays 1. Nh3 if you turn the book off. Fine. This was a short-sighted engineering decision on the part of the programmer, but the program was bug-free until someone did something unexpected. The autoplayer specified by the Fritz guys was incompatible with the Donninger autoplayer, this is not Ed's fault. It doesn't say on the Rebel box, "don't use some home-brew autoplayer with this under important circumstances that will impact my sales for years", but Ed had no reason to expect that this would happen. It isn't something that he should have had to foresee. Had Donninger done a new autoplayer, which flipped black/white between games, Ed would have gotten ahold of it, found the problems, and fixed them. It doesn't sound like he had any opportunity to do this with the Fritz autoplayer. If the autoplayer had been so incompatible with Rebel that it crashed it, the SSDF wouldn't have scored all of those games as time forfeits for Rebel, nor would you be arguing that they should, because Ed should have had the foresight to predict that one of his competitors would write a incompatible version of the software that he had come to rely upon, and mandate to the SSDF that they use it, for reasons that are still impossible to understand. The only difference here is that the SSDF probably put a lot of time into playing the games before this bug came to light, and that time would have been wasted if the games had been replayed. This is probably what should have happened though, because Rebel had a bug which probably reduced its strength, and Ed should have had a chance to fix it. Note that *nothing* I have said should be taken to mean that there was any malice on the part of the Fritz guys, nor do I think that they need to have been malicious in order to make my arguments valid. bruce
