1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 
To everyone's surprise, Shirov repeats the line against Leko, which should be a draw. Aronian was surprised too, and after the game he said "I should have played like Leko, because at several points I was lost today".
27... Bc4 28. b3 Bb5 29. Ba5 Rc8 30. Nc3 Bc6 31. Rd1 Kf7 32. Ne2 h5 33. Rc1 Bd7 34. Rxc8 Bxc8 35. Bc3 Bd6 36. Kf2 g5 37. Ke3 h4 38. gxh4 Bxh2 1/2-1/2, Shirov-Leko, Morelia/Linares 2008
28. Rd1 Bc4 29. a3 Bb5 30. g4 Bc6 31. Rd3 Re8 32. Rd4 Rb8 33. h4 Be7 34. h5 Rd8 35. Rc4 Bb5 36. Rc7 Rd7 37. Rxd7 Bxd7 38. h6 gxh6 39. Bxf6 Bf8 40. Bd4 Again the question is: how much is the bishop pair worth, one pawn exactly? Aronian felt that he should have lost this ending, but it's not so easy.
40... Kf7 41. Kf2 Be7 42. Ke3 Bg5+ 43. f4 Bd8 44. Nd6+ Ke6 45. Nb7 Be7 46. f5+ Kf7 47. Kf4 Bg5+ 48. Ke5 Ba4 49. Nd6+ Ke7 50. Ne4 Bd1 51. Bc5+ Kf7 52. b4 Bc1? This allows White to promote his pawn.
After 52... Kg7 53. f6+ Kf7 it's difficult for White to make progress.
53. Nd6+ Kg7 not better is 53... Kg8 54. Ke6 Bxg4 55. a4
54. f6+ Kg6 55. f7 Bb2+ 56. Ke6 Bxg4+ 57. Ke7 Bf6+ 58. Ke8 Bf3! 58... Bg7 59. Bd4! wins on the spot
59. f8=N+ Of course Black's defence was based on 59. f8=Q?? Bc6#
59... Kh5 60. Kf7 Bb2 61. Nxh7? Stronger was 61. a4 which should be winning according to Aronian.
61... Bxa3 62. Nf6+ Kh4 63. Ke6 h5 During this phase, Shirov had used all of his time and was playing on his 30 seconds increment. Aronian still had about an hour on the clock, but was playing along quite fast too.
64. Ke5 Be2 65. Nde4 Bc1 66. Nd5 Kg4 67. Ne3+ Kf3?! 67... Bxe3 68. Bxe3 h4 would have drawn immediately: 69. Nc3 Bf1 70. Nd5 h3 71. Bf4 Kf3 72. Kd4 Kf2
68. Ng5+ Kg3 69. Ke4 Bb5 70. Bd6+ Kf2 71. Nh3+ Ke2 72. Nf4+ Kd2 73. Nxh5?! After this move it's a clear draw, because Black will take White's last pawn.
White can win Black's h-pawn and still keep his own pawn with 73. Ned5 Kc2 74. Nxh5 Bc6 75. Ng3 Ba3 76. Ne2 but whether it's winning?
73... Bd3+ 74. Kd5 Kc3 75. Nd1+ Kb3 76. Nf6 Bd2 77. Ne4 1/2-1/2
