Perhaps I will understand your subtleties in several reincarnations... or perhaps if I had more subtle genes...or a few of those infamous German lagers... but still a great joy to discuss even our small hobby domain of computer chess :-) > > In computer - computer ratings, the ratings are >>still increasing linearly with ply.
