Qa3 Nc4 ½–½ Game 2, Anand–Carlsen, ½–½ Anand opened with 1.e4, and Carlsen responded with the Caro–Kann Defence, his first time doing so in a competitive game since 2011. Anand castled queenside on move 14, which was followed by a knight exchange in the centre, after which Carlsen advanced his queen to d5 (see diagram). This enabled a trade of queens, and, to the surprise of commentators and the audience, Anand accepted it, rather than pressing forward with 18.Qg4. The resulting endgame was balanced; Anand exerted pressure on Carlsen's kingside pawn shield with his rooks, eliciting a repetition of moves and a draw.

Anand gained some advantage in the middlegame when Carlsen had to retreat his queen to h1 and became short on time. However, with the temporary pawn sacrifice 28.e3 (which chess Grandmaster and commentator Sergei Shipov described as "the best known, boldest and most debatable" move of 2013), Carlsen opened the position and managed to reactivate his pieces. From then on Anand did not play the most aggressive moves (e.g. he chose 29...Bd4 instead of Bxb2; later 34...Rf8 was possible) but began to exchange pieces, and offered a draw after move 41, which Carlsen declined. After the exchange of queens, an opposite-colored bishops endgame was reached, and the players soon agreed to a draw. Réti Opening, King's Indian Attack (ECO A07) 1. Nf3
