However, there's a big difference between that and agreeing with Fischer's goal of "crushing the other guy's ego" or your earlier assertion that chess is about "beating someone up with your mind". I don't think that's true at all, or at least no more true of chess than any other game.
Also, I would strongly disagree with Fischer being "the archetypical chessplayer". From what I've read about chess players through the ages and from my personal experience, the overwhelming majority of chess players are nothing like Fischer.
Sure, you will occasionally find an obnoxious, childish, mentally ill genius, but that's the exception. Even non-genius chess players are generally no more childish or obnoxious than people in the general population.
And I see no evidence that the average chess player's motivation is anything like Fischer's motivation, except wanting to win and hating to lose. But that's the same for players of any competitive game.
