It leads to positions of a slow and positional character. 5... d7c6  6. e1g1  6... f6d7  7. b1d2  7... e8g8  8. d2c4  8... f7f6  9. a2a4  9... a7a5  10. f3h4 White's idea is based on playing on the kingside with the f4-break at some point. Black has the bishop pair and a solid position; the doubled pawns are not so bad. When the pawn moves from c6 to c5, Black has excellent central control. The evaluation is one of balance, but many players with White like to try this type of position as it is an anti-computer way of playing. The game is more about maneuvers and less about forced lines. 10... f8f7  11. g1h1  11... d7f8 A new and logical move: the knight protects the king and can go to e6. 12. c1e3 When your opponent has the bishop pair, exchanging one of them is usually a good strategy. 12... c5e3  13. c4e3  13... f8e6  14. h4f5  14... c6c5 This typical advance controls the d4-square and shows that the doubled pawns are far from a weakness here. The position is equal, and now a slow game of maneuvers begins, as both sides reinforce their positions. 15. b2b3  15... g8h8  16. f2f3  16... e6d4  17. f5g3  17... c8e6  18. d1d2  18... d8d6  19. f1f2  19... b7b6  20. h2h3  20... a8d8  21. a1b1 I don't see a particular idea in this move, but in this type of position, it is possible to wait before executing a plan. 21... h8g8  22. d2c3  22... g7g6  23. e3c4 Black finally has a concrete decision to make: whether to capture the knight on c4 $2 23... e6c4 There's nothing wrong with this move, but I think 23...Qd7 is a bit more accurate. 24. c3c4  24... d4e6  25. g3e2  25... g8g7  26. b1f1  26... e6f4  27. e2g1  27... d6e6 [%c_effect e6;square;e6;type;Inaccuracy;persistent;true] Dominguez chooses too solid a plan, as the exchange of queens on c4 gives White some chances with the opening of the b-file. 28. g2g3  28... e6c4  29. b3c4  29... f4e6 Caruana can now fight for the advantage, since when Black plays c7-c6 (probably necessary to prevent a knight from getting to d5), he can try to attack the b6-pawn. 30. f3f4  30... d8f8
