If I could have a lesson with one chess player, dead or alive, it would have been Daniel Naroditsky, hands down. He had a stunning combination of brilliance as a player and brilliance as an educator. By all accounts he was as kind and generous as he seemed in his online appearances. My favorite kind of nerd. He was also a sensitive and vulnerable human being.
Vladimir Kramnik is garbage. I've said before that he could go fuck himself. I meant it then and I mean it now.
