1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d3  5... d7d6  6. e1g1  6... h7h6  7. f1e1  7... e8g8  8. b1d2  8... a7a5 Nakamura is the main proponent of this line against the Italian.  He has had running mini-matches against Ding, Carlsen, and So. 9. d2f1  9... c8e6  10. c4b5  10... c5b6  11. f1g3  11... f6h7 A novelty. This idea is mostly seen in the lines where  the black bishop stands on e7. Here too, it is possible and aims to a  better control of the d4-square. 12. h2h3  12... h7g5  13. f3g5  13... h6g5  14. d3d4 So breaks through the center anyway. 14... e5d4  15. b5c6  15... b7c6  16. c3d4  16... c6c5 Black is trying to clarify the  central situation, but this leads to problems. 17. d4d5  17... e6d7  18. a2a4 An important move that keeps the black dark-squared  bishop locked. 18... f8e8  19. c1d2  19... c5c4 Nakamura is OK to sacrifice the pawn after all. 20. d1f3  20... a8b8  21. d2c3  21... b6c5 As the bishop really needs out. 22. e1e2 Preventing  the trade. 22... f7f6  23. g3f5 So is in control and has several attacking ideas available. 23... c5b4  24. c3d4 This obvious move allows Black a sudden chance. 24... b4c5  25. d4c3  25... c5b4  26. f5e3 Back to the plan from above. The c4-pawn is doomed. 26... d7c8  27. c3d4 So wants to extract the maximum from the position. 27... c8a6  28. e3f5  28... a6c8  29. f5e3 Black's position is extremely suspicious, to say the least. 29... c8a6  30. e3f5  30... a6c8  31. a1c1  31... d8d7 This attempt for counterplay loses instantly, but Black lacks good advice. The white pieces keep coming closer to his king, and h3-h4 is due to happen sooner or later. 32. e2c2  32... c8a6  33. h3h4 The inevitable happens. Black's king is due to be mated. 33... g5h4  34. f3g4 Threatening Nf5-h6+. 34... g8f8  35. d4f6 Without any hesitation. So discovers the enemy king as he  knows he has enough time to bring his pieces to support the queen and the  knight. 35... g7f6  36. g4h4  36... f8g8  37. c2e2  37... e8e5
