1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g2g3  3... d7d5  4. f1g2  4... f8e7  5. g1f3  5... e8g8  6. e1g1  6... d5c4  7. d1a4  7... a7a6  8. a4c4  8... b7b5  9. c4c2  9... c8b7  10. c1d2  10... a8a7 This move is much rarer than 10...Be4, but it hardly came as a surprise to Sevian, as Niemann had played it in 2023. This is a subtle move that delays the development of the knight, and the rook on a7 fulfills its function by defending the c7-pawn and freeing the a8-square for the queen, which will be useful after Nbd7. 11. a2a4 Black will quickly get a great position, so possibly this move is not the most accurate. 11... b5b4  12. d2g5  12... b8d7  13. b1d2  13... d8a8 [%c_effect a8;square;a8;type;GreatFind;persistent;true] This is one of the ideas of 10...Ra7. The queen goes to a8, and the other rook can come to c8, supporting the thematic c7-c5 advance. 14. f3e1 [%c_effect e1;square;e1;type;Inaccuracy;persistent;true] A new move. 14... b7g2  15. e1g2  15... c7c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] Black's position is already more comfortable. 16. g5f6  16... g7f6 White can always try to bother the kingside after this capture, so it's preferable to take it with the bishop. 17. d2b3  17... c5d4  18. a1c1 [%c_effect c1;square;c1;type;GreatFind;persistent;true] Controlling the c-file. 18... d7e5  19. b3d4  19... f8d8  20. d4b3  20... a7d7  21. g2f4 The position is more or less balanced, but Niemann will show a fighting spirit to try to unbalance the game and fight for victory. 21... g8g7 [%c_effect g7;square;g7;type;Interesting;persistent;true] 22. f4h5 [%c_effect h5;square;h5;type;Inaccuracy;persistent;true] This is an almost irresistible check, but it doesn't help White's position. 22... g7h6 A curious square for the king, but White can't exploit it. 23. h5f4  23... f6f5  24. f4g2 Sevian was probably worried about the move Be7-g5. 24... h6g7  25. c2b1 This move is a bad sign for White, as it clearly shows that he is unsure of what to do. 25... e7f6 [%c_effect f6;square;f6;type;Inaccuracy;persistent;true] 26. c1c5  26... e5g6  27. c5c4  27... f6e7  28. b1c2  28... h7h5  29. h2h4 White has managed to organize his pieces. 29... a8b8  30. c2c1  30... e7f6  31. b3a5  31... b8b6 [%c_effect b6;square;b6;type;GreatFind;persistent;true] 32. a5b3  32... b6b8  33. b3a5  33... b8b6  34. a5b3  34... g7h7  35. g2f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 35... g6e5 Black is ready to leave the h5-pawn to its fate in order to avoid the knight exchange. 36. c4c5  36... b6b7 [%c_effect b7;square;b7;type;Inaccuracy;persistent;true] 37. f4h5  37... f6h8  38. c1c2  38... d8g8  39. h5f4  39... e5g6 [%c_effect g6;square;g6;type;Mistake;persistent;true] After this, all chances of compensation for the pawn fade away. 40. f4g6  40... g8g6  41. f1c1 White has a winning position with a full pawn up, but many adventures lie ahead. 41... b7b6 [%c_effect b6;square;b6;type;Inaccuracy;persistent;true] This makes things worse. 42. c1d1 [%c_effect d1;square;d1;type;Inaccuracy;persistent;true] 42... d7d1  43. c2d1  43... h8b2  44. d1d7  44... g6g7  45. e2e3 The position is still much better for White, but it's not so easy to convert it. 45... b6b8  46. g1g2  46... b8a8  47. c5c6  47... b2e5  48. d7c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true] 48... a8a7 [%c_effect a7;square;a7;type;Inaccuracy;persistent;true] 49. c6a6  49... a7e7  50. a6a8 [%c_effect a8;square;a8;type;Inaccuracy;persistent;true] 50... g7g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] All the checks are prevented. 51. g2f1 [%c_effect f1;square;f1;type;Inaccuracy;persistent;true] 51... e7d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] The position is still very complicated, but the machine already indicates a draw with several obscure variations. 52. c8b7 A daring move, sacrificing a knight. Although objectively the game is still balanced, White has to find difficult moves in order to prove this evaluation. There are safer alternatives.. 52... d6d1  53. f1g2  53... d1b3  54. b7f7  54... h7h6 The best chance. 55. f7f8 [%c_effect f8;square;f8;type;Mistake;persistent;true] 55... e5g7  56. f8d6  56... b3c4 Black has an extra piece, and the rest is easy. 57. a8e8  57... b4b3  58. e8e6  58... h6h7  59. d6d7  59... b3b2  60. e6b6  60... c4e4  61. f2f3  61... e4c2  62. g2h3  62... b2b1q  63. b6b1  63... c2b1  64. f3g4
