Garry Kasparov (by Will Knight) "I think it's important to remember they are very different. If a human can win a game, then they can still compete. The human players are under tremendous pressure. But even with ideal conditions, there are always problems: bad weather, family problems, a headache, whatever. That's why I can hardly imagine a human player being able to play six games with the same strength, while the machine will be the same machine. That's why the longterm experiment will be whether, on his best day, the best human player assisted by a machine to prepare the game could beat the best machine. If it happens, it means we are still superior." read the whole thing here: http://www.academicchess.com/help/kasparovcomputerarticle.shtml
