They really played in this site Game 61165, or is someone with the same name?This is a so damn good game,Kramnik resigned.......
This thing about a game between users "Garri Kasparov" and "Vladimir Kramnik" has been discussed before. If I remember correctly, David Tebb pointed out that the game actually is (or repeats the moves of) an old Anderssen game.
(Yeah, that game can be found e.g. from chessgames.com: http://www.chessgames.com/perl/chessgame?gid=1019123)
