What openings will we see in the WCC?

Many lines of the Grunfeld are like that :(

Ok, that makes (counterintuitive) sense, thank you. Seemed crazily antithetical that sharp lines should lead to draws!

There has to be a Ruy in there somewhere.

Although I think that one of them will break with their usual form to try and find a way through.

Ware, Saragossa, Van't Kruijs, Trompovsky (d4, d5, Bg5)

and

Ruy Lopez, KID, Semi-Slav.

Yes they do, but typically (as of the last several years) e4 is much less common in match play / WCCs than in tournament play.

Really? Check out the last World Championship match.

Anand played more e4 than d4.

What I would like to see : 
Dragon, Caro-Khan Bronstein-Larsen, east- and king indian, benoni with black. King's gambit with white. 
That would be an awesome match !

More seriously, I think that Anand should try some tactical lines, just as he did against Kramnik in 2008. Carlsen skills have not been tested in those kind of position, he prefers calmer water. 

Anand played the scandinavian against Kasparov (and lost). 
Fischer played the Alekhine against Spassky (and won).
Obviously those were pre-computer area matches, but who knows ?
Carlsen has played some strange openings too. 

3/6 of Anand's games as white, and 0/6 of Gelfand's, so 25%.  Pretty typical.

Gelfand isn't playing, so irrelevant. Anand played e4 in 5/8.

My point was these players play quite a lot of e4, not a general evaluation of top level chess.

Surprise. Carlsen Plays KG and loses. Anand Plays QB and loses.

Carlsen will probably play sicilian or ruy lopez with either peices, Anand will probably play the same with either peices.

The Scandanavian and Alekhine are playable up there (as far as I know) whereas the King's Gambit isn't.  The Nimzo-Larsen might be, it hands black easy equality but in any opening (especially at world champion level) black equalizes eventually anyway. 

The thing I like about the Nimzo-Larsen is it gives black the option to go for a space advantage, so one as white can put into practice the old saying that just because a position is cramped doesn't mean it lacks resources. 

I remember a game where Carlsen even played the Nc3 variation of the King's Gambit!  He drew. 

My bet is that Carlsen will vary a lot, but that we will see at least two Ruy Lopez games with d3, one with Carlsen white and the other Anand.

this is definitely right. check out the lagrave vs gelfand game from the recent world cup in the exchange grunfeld for a perfect example. pretty sure they were both in preperation right the way through this game.

Most probably Ruy Lopez, QGD, Catalan, and Grunfeld. Maybe Nimzo or Slav, but I don't think Anand will dare to chose them this time.

I don't have many hopes we'll see a Sicilian.

Magnus will play the Bongcloud in game one and lose, but he'll get his king to the other side first and come so close to drawing classically that Anand will be totally demoralized. After losing 2 of the next 4 games and drawing the other 2, Anand will try reverse pyschology and employ the Ammonia Attack (1. Nh3), but Carlsen will play a reversed Bongcloud against it, winning the game according to both Bongcloud and classical chess rules.

All the rest of the games will be draws, and Anand will announce his retirement from chess immediately after the tournament, while Carlsen will announce the foudation of the BCA, an organization dedicated to Bongcloud chess, but he'll return to classical chess within a year after Lenny Bongcloud trounces him a Bongcloud title match.

Your going to see what has worked for them in the past and a couple of unorthodox openings. So i say over all the same old same old.
