1. g1f3  1... d7d5  2. e2e3  2... g8f6  3. c2c4  3... e7e6  4. b1c3  4... d5c4  5. f1c4  5... a7a6  6. e1g1  6... b7b5  7. c4e2  7... c8b7  8. a2a4 Technically speaking, a  novelty. However, White plays this move sooner or later, therefore, it  should come as a surprise for Black. Still, there is an important  difference in comparison to the usual lines. 8... b5b4  9. c3b1  9... c7c5  10. d2d3  10... b8c6  11. b1d2  11... f8e7  12. e3e4  12... a6a5 "A big mistake"  according to Artemiev. "It is not a good square (for the pawn) in the  endgame." 13. d2b3 This is the difference. The b3 spot is available  for the knight and Artemiev can put a lot of pressure against the a5 and  c5 pawns. 13... c5c4 Vitiugov decided to solve the problem of the backward pawn  at once, but this creates other issues. "Risky" said Artemiev. 14. d3c4  14... f6e4  15. d1d8  15... a8d8  16. c1e3  16... e8g8  17. e3b6 This bishop is the  problem. It paralyzes the black pieces because of the weak a5 pawn, and  provides control over the d-file for the white rooks. Artemiev also has a  valuable queenside majority. 17... d8a8  18. f1d1  18... f8c8  19. g1f1  19... e4f6  20. a1c1  20... e7d8 Finally Vitiugov decides to solve the problem of the  annoying bishop. 21. b6d8  21... c6d8  22. f3e5  22... g8f8  23. d1d6 That is one of the problems with the bishop swap.  White gets a square for his rook to infiltrate into the enemy camp. 23... a8a7  24. c1d1  24... d8c6  25. f2f4 Artemiev did not do anything exceptional and  nevertheless improved his position greatly. 25... b7a8  26. e2f3 With his next move Vitiugov makes things even worse for him. 26... c6e5  27. f4e5  27... a8f3  28. g2f3  28... f6e8  29. d6d4  29... f8e7  30. f1e2  30... g7g6 In order to bring the knight out, but Black lacks  the time for this. 31. c4c5 The passer has something to announce. 31... e8g7  32. d4d6  32... g7f5  33. d6b6 Artemiev decides to win in the most secure way. 33... f7f6  34. f3f4  34... g6g5 Looking for some activity, but this just loses the  pawn without compensation. 35. e5f6  35... e7f6  36. f4g5  36... f6g5  37. b6e6  37... a7f7  38. e6e4  38... c8c6  39. d1g1  39... g5h5  40. e4e5 White won a pawn and quickly converts  his advantage. 40... h5h4  41. g1f1  41... c6f6  42. f1f3  42... h4g4  43. h2h3  43... g4h4  44. e5e4  44... h4g5  45. e4g4  45... g5h5  46. e2d2  46... f7d7  47. f3d3  47... d7e7  48. d3d5  48... h5h6  49. g4f4  49... h6g6
