1. g1f3  1... d7d5  2. g2g3  2... b8d7 A tricky move order which aims to secure the long  diagonal for the light-squared bishop. 3. c2c4  3... d5c4  4. d1a4 Without a  check. 4... a7a6  5. a4c4  5... b7b5  6. c4c2  6... c8b7 Once upon a time the seizure of  this diagonal was considered good enough for equality. Nowadays White  tries to squeeze something out of the position. 7. f1g2  7... g8f6  8. e1g1  8... e7e6  9. d2d3  9... f8e7  10. a2a4  10... c7c5  11. b1c3  11... d8b6  12. a4b5  12... a6b5  13. a1a8 Artemiev secures the a-file before his opponent finds the time to finish the development.  Another question is how valuable this file is, as long as there are no  entry squares along it. 13... b7a8  14. c1g5  14... e8g8  15. f1a1  15... h7h6  16. g5f6  16... e7f6  17. f3d2 A novelty, which seems  logical. White wants to soften the enemy queenside. 17... a8g2  18. g1g2  18... f8c8  19. c2b3 With Ba8 alive Black could have now  defended with Ba8-c6. 19... c8b8 But here too, the flank is safe. 20. c3e4 It is not obvious what will White do next, whereas Caruana finds a  nice regroupment of his pieces. 20... f6e7  21. g2g1  21... f7f5  22. e4c3  22... d7e5 The white knights were deprived of  the good central squares, whereas the black one is ready to cause trouble  on the kingside. Artemiev stops this. 23. h2h3 But in the process weakens  the dark squares which is immediately exploited by Caruana. 23... h6h5  24. d2f3 The best chance for the first player. He needs to save-guard  his king, despite the weakening of his pawn structure. 24... e5f3  25. e2f3  25... e7f6 In any case White's position is unpleasant: he has the weaker king and worse pawn structure. 26. a1e1  26... g8f7  27. c3e2  27... g7g5 Qb6-c6 is a threat. Artemiev finds another  excellent move. 28. g3g4  28... h5g4  29. h3g4  29... f5g4  30. f3g4 Thus White secured the e4 outpost for his knight. 30... b6d6  31. e2g3  31... d6d5  32. b3c2 Correct! Despite his poor king position White  needs the queens to create counter-threats. 32... f6d4  33. c2e2  33... b8h8  34. g3e4  34... d5e5 Now the white king feels uncomfortable. 35. e2f3  35... f7g7  36. b2b3 The problem with this move is that the pawn is not safer on  b3. 36... h8f8  37. f3e2  37... e5d5  38. e1f1  38... g7g6 An important preparatory move. 39. e2d1  39... c5c4 Caruana exposes the drawback of the b2-b3 move. 40. b3c4  40... b5c4  41. g1g2  41... d4a7 Now Artemiev receives another chance: 42. f2f3 Very strong. 42... c4d3  43. d1a1 Not the right way to generate counterplay. 43... a7e3  44. f1d1  44... d5c4 Threatens mate after Qc4-c2. In order to  prevent it White needs to go for: 45. a1c3  45... c4a2  46. e4d2  46... a2c2  47. c3e5 But  now that the white pieces are pinned, Caruana has a chance to calculate  the winning line till the end. 47... e3d2 The correct capture! 48. e5e6  48... g6g7  49. e6e7  49... f8f7  50. e7e5  50... g7f8 The king is ready for a journey to Australia...  51. e5b8  51... f8e7  52. b8e5  52... e7d8  53. e5b8  53... d8d7  54. b8b7  54... d7d6  55. b7b6  55... d6e5  56. b6b5  56... e5d4
