1. h2h4 The problems start right from the first move. A chess opening that begins with 1.h4 h5 seems absurd, but in this setup it's not that bad. Of course, even here, this move is exotic. I like to start by opening the game to my bishops or my queen, and in that sense 1.b4 or 1.c4 is more natural. 1... h7h5 With Carlsen and Nakamura facing off, I'm never sure if they really believe in these opening moves or if they're just having fun. 2. d2d4 Interestingly, a move that looks natural, dominating the center, is considered inaccurate by the machine (yes, it also criticizes Fischer Random moves). 2... b7b5  3. c2c4  3... c7c5 Contact starts early and it's already time to start calculating. 4. c4b5  4... c5d4  5. c1c8  5... b8c8  6. b2b3  6... d8b6  7. e1f3  7... c8b7 After this move it's clear that Black has the advantage. Nakamura has managed to create a curious battery with the queen and the bishops and the white king is insecure. 8. a2a4  8... e7e5  9. e2e3  9... d4e3  10. f1e3  10... f7f6  11. b3b4 Advancing the majority on the queenside and preparing the bishop's development on b3. 11... f8e6  12. d1b3  12... e8c7 Now Black is in trouble. 13. e3f5  13... c7e8  14. f5e7  14... g8f7  15. e7g6 Missing a wonderful combination that wins the game. 15... h8h6  16. b1f5  16... e8d6 Magnus probably missed this resource, as this is the only move that saves Black.
