Carlsen is probably distracted because principal photography began this week on the upcoming Terminator film with Arnold Schwarzenegger. Magnus has a role he's shooting as John Connor's lieutenant and best friend in New Orleans.
He is understandably nervous as all heck since this is Carlsen's first film, ever...and it's a huge one.
I felt sorry for Magnus at today's press conference when he said that he had no energy and that it just isn't working for him at the moment. What was surprising about his loss today was that he had the whites pieces and he castled queenside against the kings indian defence. Thus inviting the threats on the long diagonal.
Perhaps Magnus has reached that age... 23/24/25 when he is becoming aware of his own mortality and he is thinking once again about carving out a legacy which shows that Magnus is more than just the ultimate positional player. I think he will have to revert to a more solid style; solid play is how he wins but Magnus may have other ideas .
The question for Magnus :"Are you going to take the green pill or the red pill ? ".
