context: 1. e2e4  1... c7c5  2. g1f3  2... e7e6  3. c2c4 An interesting sideline (if a move with more than ten thousand games can be called that) that is played by very strong GMs from time to time. 3... b8c6  4. d2d4  4... c5d4  5. f3d4  5... g8f6  6. b1c3  6... f8c5 An important moment. 6...Bb4 is by far the most popular move. 7. d4b3 It's hard to say which move is better. 7... c5b4  8. f1d3  8... e8g8  9. e1g1  9... b4c3  10. b2c3 White's pawn structure is shattered, but he has the bishop pair and Black must be careful with the dark squares. 10... d7d6 This is a bit slow and allows White to fight for the initiative. 11. c1a3 A new move. White is pressing the pawn on d6. 11... f8e8 Preparing d6-d5 in case the pawn is attacked. 12. f1e1  12... d8c7  13. b3d4 The knight goes back to the center. 13... a7a6  14. d4c6 A very deep and strong idea. Vidit uses a tactical chance to open the game. 14... c7c6  15. d3c2 A tempting move, attacking the d6-pawn and changing the character of the game. Black, however, can defend with accurate play and there was a better move. 15... c6c4  16. d1d6  16... e6e5  17. c2b3  17... c4c3  18. a1c1  18... c3a5 White gets a pleasant advantage in the forced endgame that arises after this move. 19. a3b4  19... a5d8  20. d6d8  20... e8d8  21. c1c7  21... d8d7 A difficult decision. 22. e1c1  22... d7c7  23. c1c7  23... c8e6  24. b3e6  24... f7e6  25. f2f3 This endgame is deceptive. For now Black is a pawn up, but it's clear that he will not hold a material advantage for long. The fact that White has a big advantage may come as a surprise with such reduced material. But the difference in activity between the pieces (including the king) is quite big. 25... b7b5  26. a2a3 This allows Black excellent defensive chances. 26... a6a5  27. b4c3  27... b5b4 giving back the pawn to activate the rook. 28. a3b4  28... a5b4  29. c3b4  29... a8a1  30. g1f2  30... a1a2  31. f2f1  31... a2a1  32. f1f2  32... a1a2  33. f2f1  33... a2a1  34. b4e1 Fighting for the win. White really isn't risking anything. Well, sort of... 34... f6h5  35. g2g3 Restricting the knight. 35... h5f6  36. c7e7  36... a1a3  37. f1e2  37... a3a6  38. e1c3  38... g8f8  39. e7b7  39... a6a2  40. c3b2  40... f6d7  41. e2e3  41... f8e8  42. h2h4 The advantage is not so big, but it still exists. 42... a2a5  43. b7c7  43... g7g6  44. g3g4  44... h7h5  45. g4g5 Now the g6-pawn will be a constant source of problems. 45... a5a8  46. c7c6  46... e8f7  47. e3d3  47... a8b8  48. d3c2  48... b8a8  49. c6c7  49... f7e8  50. c7c6  50... e8f7  51. c2c3  51... a8b8  52. b2a3 Black is paralyzed. 52... b8b1  53. c6c7  53... f7e8  54. c7c8  54... e8f7  55. c8d8  55... d7b6  56. d8f8  56... f7g7  57. f8f6 This gives drawing chances again. 57... b6a4  58. c3c4  58... a4b6  59. c4c3  59... b6a4  60. c3c2  60... b1b6 Black somehow managed to defend everything. But the fight is far from over. 61. a3f8  61... g7h7  62. f8h6 A very pretty idea $1 62... b6b2  63. c2d3  63... b2b7  64. h6f8  64... a4b2  65. d3e2  65... b7b6  66. f8h6 The bishop returns to its strange square. 66... b6c6  67. f6f7  67... h7h8  68. f7f8  68... h8h7  69. f8f7  69... h7h8  70. f7g7  70... c6c2  71. e2e3  71... c2c3  72. e3d2  72... c3f3  73. g7g6  73... b2c4  74. d2d1  74... f3f4  75. g6e6 Now Arjun finds the only way to save the game. 75... c4e3  76. d1d2  76... e3g4 The knight attacks and defends in this excellent outpost. 77. d2d3  77... h8g8  78. e6e8  78... g8h7  79. e8e7  79... h7g8  80. e7e8  80... g8h7  81. h6f8 Vidit knew he was winning before. Probably distressed by this certainty, he keeps pressing for a win. 81... g4f2  82. d3c4  82... f4e4  83. c4d5  83... e4h4  84. f8e7
