A common tradition in chess matches is that only the winner has to show up at the press conference. The loser is in no frame of mind for polite conversation. After a draw, both players come. Kasparov lost game three against Deep Junior today, but he showed up to talk to the crowd.
He had an online chat at AOL anyway, so he couldn't leave for his usual postgame walk. The chat was done by Garry talking on the phone and someone from AOL transcribing his words and reading him the questions. Here is a photo of his chat. Note the distinctly unhappy expression that comes from outplaying a world champion program on an eight processor computer and then blundering into a mate in five.
