That is even if it was possible for a machine to play absolutely perfect chess (i.e. 32-man tablebases!) a human GM could still draw with the White pieces by refusing to undertake anything even remotely resembling playing for a win by employing a supercautious approach. And if he's REALLY good he might be able to (very occasionally) draw as Black. In other words, our mythical 32-man tablebase machine would show that the opening position is a draw. I may be wrong, of course, but it doesn't "feel" like White has a forced win based on the fact that in any major opening system they're are lines that exist (as discovered and continually discovered by strong GM opening theorists) where Black, though under pressure, can achieve equality or at least a playable middlegame. Komputer Korner I believe came closest to the truth when he said that White cannot force a +/= and Black cannot force an = and that opening theory is and will remain in a permanent flux beteween those two. Anyway, because of the above there's never going to be a 10-0 or 20-0 defeat of a human world champion especially since 32-man tablebase are impossible (it's hard to see how some 10 to the 42nd power number of positions could ever be stored and recalled). Thus, I'd say that in a 20-game match, a 12-8 or 13-7 defeat of a human world champion (depending on how dominant he is over all the other GM contenders) would be the sign that it's over for the human race as chess champions.
