1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5  3... e7e6 This and 3...g6 are the main moves. 4. b5c6  4... b7c6  5. d2d3  5... d8c7 [%c_effect c7;square;c7;type;Interesting;persistent;true] The third most popular move. The idea is to improve the pawn structure with e6-e5 at some point, maybe even on the next move. 6. b1c3  6... e6e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 7. e1g1  7... g8e7  8. f3h4  8... e7g6  9. d1h5  9... d7d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] A new move. 10. c3e2  10... f8e7  11. h4f5  11... e7f6  12. e2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] This allows the knight to go to f4. 12... g6f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 13. h5f3  13... g7g6 White's knight is forced back and Black has a fine position. 14. f5e3  14... h7h5  15. g3e2  15... f6g5  16. h2h3  16... f4e6  17. e3c4  17... g5c1 [%c_effect c1;square;c1;type;Inaccuracy;persistent;true] 18. a1c1  18... c7e7  19. f3e3  19... g6g5  20. f2f3 A prophylactic move against g4, but preparing the break on b4 or d4 gave more chances of an advantage. 20... e6f4  21. e3d2  21... h8g8  22. e2g3  22... g5g4 A very risky move, allowing White to sac the exchange on f4. 23. f3g4  23... h5g4  24. h3h4  24... c8e6  25. f1f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 25... e5f4  26. d2f4  26... e8c8  27. b2b3 White has good compensation for the exchange, but the game remains unclear. 27... e6c4 [%c_effect c4;square;c4;type;Inaccuracy;persistent;true] This allows White to establish a strong knight on f5. 28. g3f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 28... e7f6  29. b3c4 With the strong knight and a pawn for the exchange, White's position is preferable. 29... c8c7  30. h4h5 This move gives the g5-square to Black. It would be better to leave the pawn on h4 for now. 30... d8b8  31. f4d2 [%c_effect d2;square;d2;type;Inaccuracy;persistent;true] 31... g4g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] 32. c1f1 White should probably continue the plan of the previous move: 32... f6g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] 33. d2a5  33... b8b6  34. f5g3 [%c_effect g3;square;g3;type;Blunder;persistent;true] A blunder that loses the game. 34... g5g3  35. a5a7  35... c7c8  36. a7a8  36... c8d7  37. a8a7  37... d7c8  38. a7a8  38... b6b8 [%c_effect b8;square;b8;type;GreatFind;persistent;true] 39. a8c6  39... c8d8 Maybe Caruana missed that the d6-pawn is protected. White is now a rook down and facing mating threats. 40. e4e5  40... g3e3  41. g1h1  41... e3e5  42. c6f3 The rest is not difficult: Black has many ways of winning. The material advantage is considerable. 42... f7f5  43. f3h3  43... e5g3  44. h3g3  44... g8g3  45. f1f5  45... d8e7  46. a2a4  46... b8g8  47. f5f2  47... g3g5  48. h1g1  48... g5h5  49. c2c3  49... g8a8  50. f2a2  50... a8a5  51. g1f2  51... h5h8  52. g2g4  52... h8a8  53. f2f3  53... a5a4  54. a2h2  54... a4a3  55. f3e4  55... e7f6  56. h2h6  56... f6f7  57. h6d6  57... a3c3  58. g4g5
