Ka6 63. Rxe7 Rxe7 64. Kxb3 ½–½ Game 5, Carlsen–Anand, 1–0 Anand's 45...Rc1+ was called the decisive mistake, after which White was able to defend the a3-pawn, exchange bishops, and win a second pawn. Instead, 45...Ra1, attacking White's a3-pawn, would have kept the balance. With this win, Carlsen took a 3–2 lead. Queen's Gambit Declined, Semi-Slav, Marshall Gambit (ECO D31) 1. c4 e6 2. d4 d5 3.

With 38.Qg3, Anand sacrificed a pawn in order to reach a drawn rook endgame, and a second pawn was sacrificed with 44.h5 in order to disconnect Black's kingside pawns. Carlsen continued playing and sacrificed both of his extra pawns in order to advance his f-pawn. The decisive error was 60.Ra4; instead, 60.b4 was suggested by analysts and chess engines as the only move that leads to a draw with best play, since the advancing b-pawn gives White queening threats that yield counterplay and make an exchange of rooks acceptable. After 60.Ra4, Carlsen's pawn sacrifice 60...h3 turned his f-pawn into a decisive passed pawn, and Anand resigned a few moves later. Ruy Lopez, Berlin Defence (ECO C65) 1. e4 e5 2. Nf3 Nc6 3.
