The move in the game, however, has already been tried by strong GMs specializing in the Najdorf, such as Firouzja and Nepomniachtchi. 8. f1c4  8... c8e6  9. c4b3  9... c6a5 Hunting the white bishop. 10. e3g5  10... a5b3  11. a2b3  11... f8e7  12. e1g1  12... a8c8 Now it's not so simple to exchange on f6 and put the knight on d5, since the pawn on c2 requires protection. 13. f1e1  13... e8g8  14. g5f6  14... e7f6  15. e1e2 Protecting the c2-pawn to be able to play Nd5 and then capture with the queen. 15... f6e7  16. c3d5  16... f7f5  17. e4f5  17... e6f5 If we remove the knight on f3 and the bishop on f5, then it becomes clear that White has an overwhelming positional advantage with his sovereign knight on d5. The presence of the light-squared bishop, however, compensates for the weakness in the pawn structure, as this bishop has remarkable mobility. 18. c2c3  18... f5g4  19. e2e4  19... g4f3  20. g2f3 Black has lost his bishop, but this has come at a considerable price, as now White's pawn structure has been damaged. 20... f8f7
