I wouldn't be as worried as Susan :-). The young viking is clearly on the way up and it appears he can't be stopped anylonger. He started Linares with two bangs ( win against Ivanchuk, win against Shirov). Nice, very nice. Though beating Anand today at Linares would indeed be amazing, even if Carlsen won't eventually manage that, he's now got serious chances to show he is already the right challenger of the World Chess Champ. The rest is just a matter of time.
