White has better development and central control. 10... g8f6  11. e4e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 11... f6g4  12. e5e6 A natural move, but there's an even better way to play. 12... c8e6  13. e1e6  13... g4f2 The best attempt. 14. d1e2  14... f7e6  15. c1e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 15... e8g8  16. e3f2 Positions with two minor pieces against a rook and two pawns are usually difficult to evaluate, but here it's clear that White has a big advantage. Black has weaknesses around the king, and the pieces coordinate well. Black would enjoy some relief with a queen exchange, but this is not easy to achieve. 16... d8d7  17. g2g3 The bishop is ready to go to a better diagonal. 17... e6e5  18. d4e5  18... g7e5  19. a1d1  19... d7f5  20. f1g2  20... g8h8  21. g2e4 Caruana plays safely. 21... f5f7  22. g1g2
