Carlsen to play 29.e5 with strong pressure on Black's d6-pawn. Maintaining the tension with 30.Nc3, 30.Ng3, or 30.b4 should have given White a winning game, but Carlsen erred with 30.exd6, releasing the tension and allowing Anand to recoup the pawn soon after. The players traded down to a knight endgame where White had some advantage, and Carlsen may have missed a win by playing 43.Nd6 instead of 43.Nd2. The game ended in a draw due to insufficient mating material. Sicilian Defence, Canal–Sokolsky Attack (ECO B51)1. e4 c5 2. Nf3 d6 3. Bb5+ Nd7 4. d4 cxd4 5. Qxd4 a6 6. Bxd7+ Bxd7 7. c4 Nf6 8.
