The official website's biography of the players offers that Carlsen's favorite move is 1.d4 and Anand's is 1.e4. Anand began with 1.d4 yesterday and today Carlsen opened with 1.e4. Of course, both players are versatile with plenty of experience in the full range of popular an even obscure openings.
The match, scheduled for twelve games, is taking place at the site of the Winter Olympics in Sochi, Russia.
Today's game is a Ruy Lopez, or Spanish Opening as it is also known. Already at move four, Carlsen opted for the second most popular move, which Anand had played against him earlier this year.
Carlsen,Magnus (2863) - Anand,Viswanathan (2792) [C65]
WCC Sochi (2), 09.11.2014
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d3 Bc5 5.0–0
Anand played 5.Bxc6 in Zurich. That game was agreed drawn on move 40.
In Moscow 2011, Anand played 5...Nd4 here and went on to beat Carlsen in a long game.
Although Re1 is a standard move in the Spanish, it is rare in this position.
With Anand's move, the game transposes into a somewhat larger reference set.
This move is essentially the novelty, although games in the ChessBase database include it due to presence of games among novices.

I would be inclined to maintain the bishop pair, perhaps playing a6 and tucking the bishop away on a7.

Peter Svidler suggested much later in the game that Anand's suffering may have started here with Black underestimating White's potential.
This square offers secure protection of h7 when White has not exchanged the Spanish bishop for Black's horse.

18...Qf7 was idscussed in the press conference as an improvement.

Carlsen scored an important victory. It was, "a clean win," according to Svidler.
