Candidates Tournament.
can magnus carlson cross the 3000 elo barrier

Carlsen did one bad tournament, he was upset because he lost on time unaware of the new rules. He is still the best chessplayer,
but I do think that Anand and the other big guys is to good to let him get 180 points ahead.
There is a good chance that Anand wins the candidate, and he has better chances than ever against Magnus now, because he realizes that he is good enough to have a close fight.
"Their is a good chance that Anand wins the candidate, and he has better chances than ever against Magnus now"
Anand has been playing really well lately, but will after all be 47 next year. It would be very impressive if he could win the Candidates again, but my bet is Caruana.

2900 is still definitely possible, although quite difficult. Magnus may have a hot streak one day and get there, even if he doesn't manage to stay there consistently.
3000 is definitely no, unless rating inflation actually exists, which I don't personally think it does.

I don't think anyone's chances against Magnus are good at this point.

I would like to see Aronian win the candidates. Not because he is Armenian, but because I think he is most likely to put pressure on Carlsen in multiple games. Carlsen wasn't really under much threat of losing either of his last two matches
I think Anand was nervous in Chennai, still nervous, but more relaxed in Sochi, and even more relaxed in the game where he met Carlsen in Stavanger. Therefore I guess that next time the gap will be closer than ever. If Anand is fantastic and lucky in game one, then Carlsen will feel pressure and headache, and the match will be very different.
Both players are extremely good chessplayers, and I guess its the phsycic things that will make a difference. Carlsen is younger, and will have a small advantage.

Caruana, Topalov, and Nakamura all have better chances of winning the Candidates' tournament than Anand. Anand's great, but I think the other three will do better in the next Candidates. Of course, I have been wrong before.
definitively not, unless FIDE politics push for it, then yes, by all means, yes.
