The game is once again balanced.
1. c2c4  1... e7e5  2. b1c3  2... f8b4  3. d1b3 [%cal dd1b3][%c_arrow d1b3;keyPressed;none;from;d1;opacity;0.8;to;b3;persistent;false] \"A modern line and the first line of some chess engine.\" (Korobov) 3... a7a5  4. g2g3  4... g8f6  5. f1g2  5... e8g8  6. g1f3  6... b8c6  7. e1g1  7... f8e8  8. d2d3  8... c6d4 \"I was out of book—I did not know what to do.\" (Korobov) 9. f3d4 This turned out to be a novelty. 9... e5d4  10. c3e4  10... f6e4  11. d3e4 An unusual situation has arisen. Both central pawns are doubled and weak, and both sides try to attack them as soon as they can. 11... b4c5  12. b3d3  12... d8e7  13. b2b3  13... d7d6  14. c1b2  14... f7f5  15. b2d4  15... f5e4  16. d3c3 Both the weaknesses have disappeared and Black can be happy with the outcome of the opening. The powerful e4-pawn has raised his chances for a kingside attack. 16... b7b6  17. a1d1  17... c8b7  18. e2e3 Once the center is stabilized, White intends to harass the enemy dark-squared bishop. 18... h7h5 Abdusattorov is full of optimism. 19. c3b2  19... h5h4  20. d4c3 In order to trap the bishop. 20... c7c6 Ambitious again. 21. a2a3  21... d6d5 The threat has borne fruit. Now the d5-pawn will be a target. 22. b3b4  22... c5d6  23. c4d5  23... c6d5  24. d1d2 Intending to double the rooks along the d-file and sacrifice the exchange for the central pawn. Korobov is also searching for a chance to make it to the overexposed black king. 24... e8c8 Black postpones kingside action and looks for counterplay on the open files. 25. f1d1  25... a5b4  26. c3b4  26... d6b4  27. a3b4  27... c8c4  28. d2d4  28... a8c8 The threat of a second (first) rank invasion forces White into a concession. 29. d4c4  29... d5c4 A strong passer has emerged from the counterplay. Still, Korobov felt he could never lose this game due to the vulnerable black king. 30. b2d4 Setting up a trap. 30... e7e6 Solidifying the position $1 31. b4b5 Separating the pawns seems obvious, but this loses an important tempo. 31... c4c3  32. d1c1  32... e6f6  33. d4d7 The black king is weak, so the queens need to stay $1 33... f6f7
