And the battle is hot, and they call it Nimzo-Indian, a main player in Carlsen's repertoire with black pieces...

P.S.
15 moves, and still opening theory.

I'm running a parallel analysis with Android Shredder on my tablet. First time I do it like this, normally I would use my PC (more CPU power). Surprisingly, the Shredder on Android Samsung Galaxy 10.1 currently reaches the same analysis depths like Komodo and Houdini, currently digging 17-18 half-moves deep. Those tiny little tablets have gone a long way...

In all matches so far, the three engines they use on the website I linked to, behaved the same way. Stockfish is the most "nervous" evaluator, spiking higher and falling deeper than the other two. Houdini is the calmest of the three, and not easy to be impressed, often having its graph moving slightly around the neutral 0-line. Komodo dances between the two other engines evaluation: not as active as Stockfish's and not as inactive as Houdini's evaluation graph.

P.P.S.
move 16, they have left theory, according to my database, but I am using a small and old one currently. White tries to push his isolated pawn on d5, but an enforced exchange of figures could be ahead.

P.P.P.S
Black accepts to exchange his advanced but isolated d-pawn. Now their bihsiops are facing each other on open diagonal line b7-g2 and maybe get exchanged next. Then we would almost be in an early endgame already. Moves so far: 18.

I wonder whether Carlsen with Black would accept this position to only score a draw in the end, because he is famous for wringing a position endlessly until he squeezes out some tiny advantage, and he does that when other players often would have given up and agreed a tie already.
