However, the move order  chosen by So seems to discourage the standard development of the black  pieces. 13... d8c7 Vachier-Lagrave is not afraid of ghosts. 14. e2f3  Overprotecting the pawn. 14... f8d8 [#] 15. c3d5 So decided to go for it anyway, and this  turned out to be a novelty. 15... e6d5  16. c4d5  16... c7d7  17. d5c6  17... b7c6 The same old problems with the e4 pawn appear for White. 18. d1d4  18... d6d5 And Vachier-Lagrave tries to clarify  the situation at once. 19. e4e5  19... f6e4 Black often solves his problems thanks to this monster knight  in the center. 20. f1d1  20... d7e6 Alas, a very unfortunate square for her  majesty. 21. h2h3  21... f7f5  22. d4d3 So found it. The queen stepped back to open a  square for the knight. 22... c6b7  23. b3d4  23... e6f7  24. c1c8  24... d8c8  25. g2g4  Now White has a super-knight as it is nicely orchestrating White's attack, whereas the opponent's knight lacks support. 25... g7g6  26. g4f5  26... g6f5  27. g1h2 Once the Black position has been opened So starts a decisive kingside attack. 27... g8h8  28. d1g1  28... c8g8  29. g1g8 Practical, fast, and strong. 29... h8g8  30. d3b5 Logical and beautiful at the same time. White was dominating the  center at first, then launched a dangerous kingside attack thanks to this  fact, and finally infiltrates on the opposite wing. 30... e7c5  31. b2b4  Blitz, blitzing. 31... c5d4  32. e3d4  32... g8f8 Now Vachier-Lagrave stabilizes the position.  33. b5e2  33... f7g6 Black's pieces wake up from the slumber. 34. e2e1  34... g6h6  35. e1c1  35... h6g7  36. c1g1  36... g7g1 But that is a mistake. 37. h2g1 Now So will definitely press with his bishop pair and defended  passer. 37... b7c6  38. f3e2  38... c6a4  39. g1g2  39... f8e7  40. e2d3  40... e7e6  41. g2f3  41... e4d2 Active defense is  best. 42. f3g3  42... d2c4  43. g3h4 The last chance which suddenly works. 43... a4e8 With seconds on the clock Vachier-Lagrave tries to play it  safe, but this loses. 44. h4g5 Once that the white king infiltrates, White's win is only a  question of time. 44... e8g6  45. a3a4  45... c4d2  46. g5h6  46... d2f3  47. d4f2 The h-pawn marches and destroys Black's  last stand. 47... f3d2  48. h3h4  48... d2e4  49. f2e3  49... e4c3  50. a4a5  50... c3a2  51. h4h5  51... g6e8  52. a5b6  52... a7b6  53. h6g5  53... h7h6  54. g5h6  54... a2b4  55. d3e2  55... b6b5  56. h6g7  56... e8h5  57. e2h5  57... b4c2  58. h5f7  58... e6d7  59. e5e6  59... d7d6  60. e3c5  60... d6c5
