This move is one of many possible attempts to confuse the opponent. While it's impossible to prove a scientific advantage, at least White can try to pose practical problems. This strategy will succeed in the present game. 7... b8d7  8. g1f3  8... e8g8  9. f1e2  9... d7b6 This is the first important moment for opening theory. 9...c5 is also possible and was played in 2019 in a game of the highest caliber. But the move played is an even better way to equalize. 10. a4b4  10... d8d6  11. e1g1  11... c8g4 This move is rightly criticized by GM Yermolinsky in his analysis of the game Inarkiev-Li Chao. 12. b4b3 Avoiding the queen exchange. 12... g4e6 The first new move of the game. It looks strange to go back with the bishop, but Black is luring White into playing d4-d5, as this will increase the scope of the g7-bishop. 13. d4d5  13... e6g4  14. h2h3 This is not the most accurate. White can fight for an advantage with 14.Rb1 or 14.Rd1. 14... g4f3  15. e2f3  15... c7c6
