comment: Preparing to bring the knight to e3, but this is a little slow.
context: 1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. d4b3 The ultimate prophylactic move. White takes the knight out before the thematic e7-e5, which is fundamentally Black's plan after a7-a6. The move is still possible, but it's a bit discouraging to play it when your opponent has already taken the knight out of d4. 6... e7e6 Probably the most logical move, leading to a Scheveningen pawn structure. Kasparov would certainly approve. 7. g2g4  7... b7b5  8. a2a3 Necessary precaution. 8... c8b7  9. f1g2  9... b8c6  10. g4g5  10... f6d7  11. h2h4  11... a8c8 Both sides had alternatives, but we cannot deny that all the moves were normal after the exotic 6.Nb3. 12. d1e2  12... f8e7  13. f2f4  13... h7h6 A new move. 13...Nc5 and 13...0-0 were tested in correspondence games. 14. e1g1 A surprising move. One would imagine that White should castle queenside, especially after the opening of the h-file. 14... h6g5  15. h4g5  15... d7b6 Black is in time with this thematic knight maneuver. 16. a3a4 A very difficult move-White advances on all sides of the board. Abdusattorov at this point probably realized that his position wasn't very good. 16... b6c4  17. a4b5  17... a6b5  18. e2f2  18... b5b4  19. c3d1  19... c8a8  20. a1a8  20... d8a8  21. b3d2  21... c4d2  22. c1d2  22... e7d8 An excellent plan to activate the bishop. 23. b2b3 A patient move, solidifying the queenside and maybe preparing a route for the knight via the b2-square. 23... a8a5  24. d2e3 Necessary to prevent Bd8-b6. 24... b7a6  25. f1e1  25... e6e5 Not afraid to allow f4-f5. With the rook on h8, Black always has counterchances. 26. f2d2  26... d8c7  27. f4f5 After this, Black has the advantage again. 27... c6d4 The thematic move. It's always dangerous for White to take the knight due to the dark squares, although in some cases this is the best move.
