It's an interesting game and a bit of a man-bites-dog story, so following a reader suggestion (third comment down) I've annotated the round 1 upset win by Hjorvar Steinn Gretarsson (an FM, not to be confused with GM Helgi Gretarsson) over the famous super-GM Alexei Shirov. Most of the sources for games from this event - including the official site(!) - failed to include the game, but an Icelandic site was understandably happy to supply it.
Have a look, here.
