1. d4 Nf6 2. c4 g6 3. f3 d5 4. cxd5 Nxd5 5. e4 Nb6 6. Nc3 Bg7 7. Be3 O-O 8. Qd2 e5 9. d5 c6 10. h4 cxd5 11. exd5 Na6!? This is a pretty uncommon move and the strongest player to have tried it is rated around 2400. 11... N8d7 is much more common. 12. h5 Nb4 13. hxg6 Bf5!? What an interesting idea by Caruana: giving up two pawns and using his lead in development to create dangerous threats. Although it looks totally scary for White, Anish kept his cool and was able to extinguish Black's initiative. 13... hxg6 14. Rd1 Bf5 15. Bh6! 14. gxh7+ Kh8 15. Rd1 Nc2+ 16. Kf2 Nxe3 17. Qxe3 Bd7 Caruana played this with the idea of f5, but turns out that it wasn't particularly good. 17... Rc8 was much better. 18. Nh3 f5 19. f4! A strong positional move by Anish. 19... Rc8 20. g3 20. fxe5 f4 21. Nxf4 Qg5 22. g3 Bxe5 20... Nc4? The biggest mistake of the game. After this Anish should have won. 20... e4 was better. 21. Bxc4 Rxc4 22. fxe5 White is just two pawns up without any compensation. 22... f4 Fabiano realises that he is completely lost and tries to sacrifice more material to complicate the issue. 23. Nxf4 Qg5 24. Rd4 The most normal move from the human point of view. 24. e6 Rcxf4+ 25. gxf4 Rxf4+ 26. Ke2 Bb5+ 27. Nxb5 Qg2+ 28. Kd3 Qg6+ 29. Kd2 Qg2+ 30. Qe2 Rf2 24. Ke1! This was the move that would have given Anish victory. However, for a human it is not so easy to find. 24... Bxe5 25. Ng6+ (25. Qxe5+ Qxe5+) 25... Qxg6 26. Qxe5+ Qg7 27. Qxg7+ Kxg7 24... Rxd4 25. Qxd4 Bxe5 26. Qb4! Of course this was the point of Rd4. The rook on f8 is hanging and White keeps his advantage. 26... Rf7 26... Re8 27. Kg2 27. Nce2 Bg4 28. Qe4 Qf6 28... Bxe2 29. Kxe2 Bxf4 30. Qe8+ 29. Rh4 Bf5 30. Qe3 b6 Although White has three extra pawns it is extremely difficult for him to convert because the two bishops control many squares and it is not so easy to advance the pawns. 30... Bxb2 31. Qxa7 31. b3 Re7 32. Qd2 Rc7 33. d6 Although the computer gives many different ways for White to play for the advantage, Anish finds this the most human, clearing the d5 square for his pieces. 33... Bxd6 33... Qxd6 34. Qxd6 Bxd6 should also be defensible. 34. Qd5 Rf7 35. Kg2 Bc5 36. Rh5 36. b4!? Bxb4 37. Nd4 36... Bg4 37. Rh6 37. Rg5 Bxe2 38. Qa8+ Rf8 39. Rg8+ Kxh7 40. Rxf8 Bxf8 41. Nxe2 is similar to what was reached in the game, but with the different bishop. 37... Qxh6 38. Qxf7 Qc6+ 39. Nd5 Be6 40. Qf6+ Kxh7 41. Qh4+ Kg7 42. Qg5+ Kf8 42... Kf7 43. Nef4 Bxd5+ 44. Qxd5+ (44. Nxd5 Ke6=) 44... Qxd5+ 45. Nxd5 Ke6 46. Nf4+ Kf5 47. Kf3 This should most probably end in a draw although it is not 100% clear as Black cannot easy exchange the queenside pawns. 43. Qf6+ From here on the players make a lot of moves and a lot of checks. Suffice it to say that White is still better, but with the two bishops around the black king it is extremely difficult to break through. 43... Kg8 44. Qg6+ Kf8 45. Qh6+ Kg8 46. Qg5+ Kf8 47. Nef4 Bf7 48. Qe5 Kg8 49. Kh3 Qd6 50. Nf6+ Kf8 51. Qf5 Ke7 52. N6d5+ Kf8 53. Kg4 Bd4 54. Nc7 Be5 55. Ncd5 a5 56. Qc8+ Kg7 57. Ne3 Kh7 58. Qb7 Kg8 59. Qa8+ Qb8 60. Qe4 Qd6 61. Nf5 Qd1+ 62. Ne2 Bg7 63. Nxg7 Kxg7 64. Qe5+ Kg6 65. Kf3 Qd3+ 66. Kf2 Qc2 67. Qd6+ Kg7 68. Qd4+ Kg8 69. Qg4+ Kf8 70. Qa4 Be8 71. Qa3+ Kg8 72. Qe7 Bf7 73. Qd8+ Kg7 74. Qd4+ Kg8 75. Qa4 Qd2 76. Qg4+ Kf8 77. Qc8+ Ke7 78. Qc7+ Kf8 79. a3 Bxb3 80. Qb8+ Kf7 81. Qb7+ Kg8 82. Qxb6 Qa2 83. Qd8+ Kf7 84. Qd7+ Kg8 85. Qe8+ Kg7 86. Qe7+ Bf7 87. g4 Qd2 88. Qc5 Be6 89. Qe5+ Kf7 90. g5 Qa2 91. Qf6+ Ke8 92. Qh8+ Ke7 93. Qh7+ Kf8 94. Qh8+ Ke7 95. Qg7+ Ke8 96. Qh8+ Drawn due to three fold repetition. 1/2-1/2 [Sagar Shah]
