1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. c1g5  6... b8d7  7. f1c4  7... d8a5  8. d1d2  8... h7h6  9. g5f6 Firouzja is ready to part with his important bishop in return for some extra time for piece mobilization. 9... d7f6  10. e1c1  10... e7e6  11. c4b3  11... f8e7  12. c1b1  12... c8d7  13. f2f4  13... a8c8  14. h1e1  14... c8c5 So far both players were playing  very fast. Now Firouzja uncorks a novelty. 15. d2e2 A novelty. White is quickly preparing the e4-e5 central break. 15... e8g8 The first lengthy thought by Korobov led to king evacuation  from the center. 16. e4e5  16... d6e5  17. f4e5  17... f6h7  18. d4f5 The major point behind the pawn  break. 18... a5d8  19. e2d3  19... c5c7  20. e1e4 White is shifting the rook on the fourth rank for either tripling of the major pieces on the d-file, or for  a kingside attack. 20... e7c5 This takes away the d4 square from the rook and opens the  road for the queen on the kingside. 21. f5g3  21... d8g5  22. h2h4  22... g5e7 An unfortunate retreat. 23. e4g4 Now the rook does a tremendously good job. Black is soon forced  to weaken himself. 23... g8h8  24. g3h5  24... g7g6  25. h5f4  25... f8g8  26. c3e4  26... h6h5 It seems as Korobv is taking over the initiative, but Firouzja has it all covered. 27. f4h5 Brilliant stuff! 27... g6h5  28. g4g8  28... h8g8  29. d3g3
