It is an upside-down situation straight from the beginning.

Carlsen needs to choose carefully. 10. c3a4 The only move. 10... b6c7 Also an only move by Arjun, as the queen needs to hit the h2-pawn as well as the g3-square. 11. a4c5  11... f2h1  12. d2f4 An unfortunate novelty which will not attract followers. Carlsen believes that he has the time to cover his kingside but forgets the opposite wing. 12... c7a5 Ooops... 13. b2b4  13... c6b4  14. e1d1  14... h1f2 The knight is out, and the game is over before it even started. 15. d1e2  15... b4c2  16. c1e3 Carlsen tries at least to confuse his opponent. 16... c2a1  17. f4e5
