Carlsen is coming off a long break. It's no surprise that he's not playing as well as usual. It's shocking that he lost on time in a completely won position then lost 2/3 games. He will certainly raise his game again. Even with this terrible performance, he's still #1 by a large margin.

I'm thinking that the next event for Magnus will be quite different. He's going to be online after this is over reading all the stuff said about his performance & how players are showing that he's not as good as a lot believed, that they've figured his game out, how he ain't really all that, etc, etc. Now, if he comes back & has another sub par finish then I'll be stunned & maybe start wondering the same thing. But I don't think so, I think he's going to go fuggin beast mode in the next tournament. We'll see.
I have a feeling Carlsen doesn't care about what people online think.
lol. Yes we can!
