Interesting that Anand didn't play 11...Nf6 12.0-0 Bf5 which seems totally equal. He is one of the best prepared players in the world, so what happened..?

I think it's fate that Anand wins this match. I doubt it being held in India will impact Anand, I'm sure he and his team will have prepared intensely for this match. All the pressure is on Carlsen to win. Lets not forget Carlsen stumbled over the line in London on tie breaks. If Anand does win this match, I hope the chess community gives Anand the respect he deserves, it will complete his legacy. I really hope it doesn't turn into a "I can't believe Carlsen lost" type of hysteria.

I think Carlsen will simply outplay Anand, and that it will either end up +2 for Carlsen or--if Anand cracks, + 3 or more. Kramnik commented that Anand is a little bit afraid of Carlsen, and that does not bode well for the champion. 

I also think that Anand's consenting to have the match in Chennai is already a concession on his part--he has commented that it was exceedingly difficult to play against Kamsky in India, and spoke with his actions when he chose to play Topalov in Sofia. Let the opponent deal with that stress! So this time, it seems to me, Anand is already in a (generous) valedictory mood.  That would be another similarity with Lasker-Capablanca, and, as in that earlier match, a serious omen of the outcome.

Regarding the age issue: another comparison might be the Botvinnik-Petrosian match, where the champion was 52, 18 years older than the challenger. It is notable, however, that there the match remained tied after 14 games: only after game 15 did Petrosian run away with it. It is possible, therefore, that age will not be much of a factor in this shorter match.

Anyway, Anand has been a worthy champion. It's pleasant to to reflect that, regardless of the outcome, the crown will be in good, gentlemanly hands. There will be no need for a "human cluster" of concerned champions to forestall anyone's victory this time.

Well, as wrote earlier - if there is a tiebreak it should have its own poll, as speed chess or blitz would be another matter entirely.

But your comment may explain why no one has voted for a drawn match, which is strange considering that the most common expectation for each player is only a +1 win.

It seems that betting on Anand will at least give you good odds! : )

Still, Anand is a much more experienced match-player (has Magnus even played a match before?) and theoretically I think he also has an edge, while youth and general playing strength is on Carlsen's side.

Anyhow, someone asked me yesterday what previous WC-match this one is most similar to? So, I'm forwarding the question here...

My response was Lasker-Capablanca, though I think Lasker was clearly older than Anand is, but at least it fits the "wily experience vs stronger youth"-description...

You left out one option: the match does not take place at all.

Yes and yes quite likely I think
