Magnus got one minute for each move. Three Norwegian grandmasters – Simen Agdestein, Jon Ludvig Hammer and Leif Erlend Johannessen – would make recommendations, and then Norway would vote online. The opponents had five minutes for each of their moves. There was a special rule: three times during the game Magnus' opponents could consult the computer – specifically the chess engine Houdini.

Now let us get to the game, which is commented in the following video by GM Daniel King:

The game lasted just over four hours and ended in a very tricky draw

There are a number of videos from the event on the VG site, showing the action as it
happened – all commented in wonderfully eloquent Norwegian

Always up for a prank: we are told that Magnus occasionally voted on behalf of his
opponents, who were probably reluctant to give up a queen for nothing...

After the game Magnus was asked if he was most impressed by the play of the grandmasters, the public or the computer. With a cough and a sly smile the World Champion replied: "Houdini really impressed me, but I was also impressed by the efforts of the people." At the end of the game he had to decide whether to risk playing for a win with some "fireworks" but decided to go for the draw.

Magnus has agreed to play a revenge match, but the next time with the white pieces. In this game he was fine with the one minute he got per move, except that when the computer found an unexpected resource he would have liked to think longer. So he has proposed a new rule for the next time around: each time the opponents consult the computer he should get some extra time – perhaps a time wild-card he can use whenever he needs it.
