Nepomniachtchi said in the press conference that he wasn't surprised. 4... c5d4  5. e3d4  5... d8c7  6. c2c3  6... c8d7 This is a new move in this position and it's hard to understand its merits, although it was clearly part of the preparation. 7. f1d3  7... b8c6  8. e1g1  8... d7g4 I don't want to sound harsh, but the fact that Black can play this position even a tempo down says a lot about the merits of White's opening. 9. f1e1  9... e7e6  10. d2f1  10... f8d6  11. c1g5  11... e8g8 [%c_effect g8;square;g8;type;GreatFind;persistent;true] Not afraid of doubling pawns. 12. g5f6 Ding thought for half an hour before taking the knight. He was evaluating the consequences of 12.Ng3. 12... g7f6  13. f1g3  13... f6f5  14. h2h3  14... g4f3  15. d1f3  15... c6e7 A nice maneuver, bringing the knight to the kingside, where it protects the king and also helps a potential attack on the g-file. 16. g3h5  16... g8h8  17. g2g4 A double-edged move, but risks are necessary when one desperately needs to win. 17... f8g8  18. g1h1  18... e7g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] Nepomniachtchi reacts very well. To be fair, he played the first part of the game excellently. 19. d3c2 [%c_effect c2;square;c2;type;Mistake;persistent;true] Black gets a clear advantage after this slow move. 19... g6h4  20. f3e3  20... g8g6 Nepomniachtchi prepares to double rooks on the g-file. The attack is very strong.
