1. e2e4  1... c7c6  2. d2d4  2... d7d5  3. e4d5  3... c6d5  4. f1d3  4... b8c6  5. c2c3  5... e7e6 This is historically not a very popular move. Usually, Black tries to develop the c8-bishop before playing e6. This move, however, was played by Carlsen and Caruana, among others. 6. c1f4  6... f8d6  7. f4d6  7... d8d6  8. g1f3  8... g8e7  9. e1g1  9... e8g8 The pawn structure resembles the London System. 10. f1e1 The rook now supports a knight move to e5 and also allows the Nd2-f1-g3 maneuver. 10... f7f6 A good move, avoiding Ne5 and preparing e6-e5. 11. c3c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] After the slight weakness created by f6, this move becomes more attractive. 11... d5c4 The best move and also a novelty. 12. d3c4  12... e7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Another good decision. 13. d4d5  13... e6d5 [%c_effect d5;square;d5;type;Mistake;persistent;true] White gets a clear advantage after this mistake. 14. c4d5  14... g8h8  15. b1c3 Anand probably underestimated the danger of this position. Even though the pawn structure is symmetrical, White has a healthy advantage with more active pieces. 15... c8d7  16. d1b3  16... d6c7  17. a1d1  17... a8d8  18. h2h3 These patient moves are always difficult to spot, and we should learn with them. White's advantage is not going anywhere, so Carlsen gives his king some useful room to breathe. 18... d7c8  19. b3a3  19... f5e7  20. c3b5  20... c7b6 This wins a pawn but gives Black some hope after the exchanges. There were many tempting moves for White. 21. b5a7 [%c_effect a7;square;a7;type;Inaccuracy;persistent;true] 21... e7d5  22. a7c8  22... d8c8  23. d1d5  23... c8a8  24. a3b3  24... b6b3  25. a2b3 After this forced sequence, White remains a pawn up, but the b-pawns are doubled. Black has serious drawing chances. 25... f8f7 [%c_effect f7;square;f7;type;Inaccuracy;persistent;true] 26. e1e4 [%c_effect e4;square;e4;type;Inaccuracy;persistent;true] 26... h8g8  27. b3b4  27... a8d8 [%c_effect d8;square;d8;type;Inaccuracy;persistent;true] 28. d5d8  28... c6d8  29. g1f1 The endgame is probably lost now. White's king is coming to the game, and a pawn is a pawn, even if it's doubled. 29... g8f8  30. f1e2  30... f7c7  31. e2d3  31... f8f7  32. f3d4  32... d8c6  33. d4c6  33... c7c6  34. e4c4 This is one of the advantages of having a pawn up: Black can never exchange rooks. 34... c6d6  35. c4d4  35... d6b6  36. d4d7  36... f7g6  37. d3c4  37... b6c6  38. c4b3  38... b7b6  39. d7d2 Preparing Ka4-b5. The rest is easy for Carlsen. 39... c6e6  40. b3a4  40... e6e5  41. f2f4  41... e5e4
