Firouzja, on the other had, faced this move in the Candidates Tournament. 6... c7b8  7. f1d3  7... a7a6  8. d4c6  8... b7c6 It seems that this capture is the best, at least that's the computer's opinion, and most GMs agree with it. 9. b5d4  9... f8d6 A move only played once before. 10. d4f3  10... g8e7  11. b2b3 A new move. It's useful for White to delay castling because one of the possible plans involves h4-h5. 11... e7g6  12. c1b2  12... f7f6  13. h2h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 13... g6f4  14. g2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] 14... d6b4  15. e1f1  15... f4d3  16. d1d3  16... d7d5 [%c_effect d5;square;d5;type;Inaccuracy;persistent;true] This move allows White to close the center, reducing the potential of the dangerous light-squared bishop. 17. e4e5  17... e8g8  18. h4h5  18... f6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 19. h5h6  19... g7g6
