The idea, I think, is to remove White's option to move the bishop to the g5-square. 8.Be3 is not attractive now due to 8...Ng4. Apart from that, the h7-square can be useful for the knight when preparing the typical f5-break, as we will see in the game. 8. f1e1  8... b8d7  9. e2f1  9... b7b6 [%c_effect b6;square;b6;type;Interesting;persistent;true] An extremely rare move. 10. d4d5 Maybe White should wait a little longer before closing the center. 10... a7a5  11. g2g3  11... d7c5  12. f1g2  12... f6h7 Preparing the typical action derived from this pawn structure. 13. c1e3  13... f7f5  14. e4f5  14... g6f5  15. f3h4 Both sides were probably happy with this position since it was later played again in the match. 15... d8f6  16. g1h1  16... e5e4  17. c3b5  17... c5d3  18. e1f1  18... f6b2  19. a1b1 Only here Gukesh deviated and chose 19... b2a2
