context: 1. f2f4 One of the most interesting things about this tournament is looking at how the \"theory\" of each position developed in the other games of the round. This first move was tried in three games, while in two the always good 1.e4 was chosen. 1... f7f5  2. g2g3  2... g7g6  3. e2e4 White strikes in the center. It's also possible to finish development first. 3... f5e4  4. e1e4  4... d7d5  5. e4e2  5... b8d7 It's not clear that this is the best square for the knight. 6. d2d4  6... h7h6 The idea of ​​this move is to break the white structure with g6-g5 and offer the excellent b1-h7 diagonal for the bishop. This could also be done immediately with 7. d1e3  7... c7c6  8. c2c3 Defending the pawn, but White has an interesting alternative: 8... g6g5  9. b1d2  9... g5f4  10. g3f4  10... g8h7  11. c1a1  11... e7e6  12. d1e1  12... e8g6 The queen and bishop battery looks very dangerous, but the knights keep the king safe for now. White can try to disrupt the battery since the queen is somewhat exposed on g6. 13. f1f3  13... d8f7  14. h1g2  14... c8a8  15. g2h3  15... f7d6  16. f3g3  16... g6f7 Black's position is a bit more comfortable, but nothing is too dangerous. 17. e3g4  17... d6f5  18. g3f3  18... f7g6  19. e2d1  19... h6h5  20. g4e3  20... f5d6  21. g1f2  21... d8e8  22. e1g1  22... g6f7  23. f2g3  23... d6f5  24. e3f5  24... h7f5  25. h3f5  25... f7f5  26. g1e1  26... h8f6  27. d1c2  27... f6d8  28. f3e3 This loses a pawn. 28... h5h4  29. c2f5  29... f8f5  30. g3f2  30... f5f4  31. f2g1  31... f4g4 Black is a safe pawn up, and the advantage increases in the next moves. 32. h2h3  32... g4g2  33. e3e2  33... g2g3  34. e2e3  34... e6e5  35. d4e5  35... e8e5  36. e3e5  36... d7e5  37. c1c2  37... e5d3  38. e1f1  38... g3h3  39. g1a7  39... d8g5  40. f1f8  40... c8d7  41. d2b3  41... d3f4  42. b3c5  42... d7e7  43. f8f5  43... g5h6  44. a7b8  44... h3f3  45. b8f4  45... f3f4  46. f5h5  46... h6g7  47. h5g5  47... g7f6  48. g5g2  48... h4h3  49. g2e2  49... e7f7  50. c5b7  50... f4h4  51. e2h2  51... f6e5  52. h2h1  52... f7e7  53. b7c5  53... h3h2  54. c5d3  54... e5d6  55. d3e1  55... h4g4  56. e1f3  56... g4g2  57. c2b3  57... c6c5  58. a2a4  58... e7d7 Safely bringing the king closer to the passed pawn. 59. a4a5  59... d7c6  60. h1a1  60... g2f2  61. f3h2  61... f2h2 Black had many ways to win, and the technique was quite good until this point. Let's not forget, however, that this is a rapid game and strange things happen when the players are low on time. There's always hope in these situations. 62. a5a6  62... c5c4  63. b3a4  63... d6c5 The a-pawn is unable to advance. 64. b2b4  64... c4b3  65. a4b3  65... c5a7  66. a1f1  66... h2h8  67. f1f6  67... c6c5  68. f6f7 The win has become problematic. Black needs to find a difficult move. 68... a7b6  69. f7f5 The final mistake. There is a miracle drawing idea available. 69... h8h1  70. f5g5  70... h1b1  71. b3c2  71... b1b5 The pieces coordinate, and it's over. 72. g5h5  72... b5a5  73. c2b3  73... c5c6  74. h5h6  74... c6b5  75. h6h5  75... b5a6  76. b3c2  76... a6b7  77. c3c4
