If not, oh well. Pretty much. I have watched players get more and more comfortable with computers over the years and in the process learned a lot about how to exploit them. But they have learned pretty much all the problems, they have little else to learn so I don't think they'll get much better against computers than they already are. If they play a single computer opponent in a long match they will not learn additional anti-computer strategies (or at least very litle), but they will definitely learn some things about that particular computers strengths and weakness. But the computer team also learns things. This helps (but doesn't fully compensate) things a bit. So I won't go so far as to say this is not relevant, it is. One thing never discussed is that it is NOT a computer against a human. It is really a human playing against a device designed by other humans. In other words the whole thing is a competition between humans. Creativity, skill, learning ability and all of things that are atributed to the grandmasters are also qualities the computer team has and uses. It's my opinion that humans adapt and I'm not speaking only of the human GM opponent. - Don
