1. d2d4  1... g8f6  2. g1f3  2... b7b6  3. g2g3  3... c8b7  4. f1g2  4... g7g6 The double fianchetto is perhaps better than its reputation. It's a strategically risky system because it doesn't directly fight for control of the center with the pawns, unlike what would happen with …e7-e6, which supports the …d7-d5 advance. 5. c2c4  5... f8g7  6. e1g1  6... e8g8  7. d4d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] The critical move. 7... b8a6  8. b1c3  8... a6c5  9. f3d4  9... e7e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 10. d4b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] The most challenging move. 10... d7d6  11. b3c5  11... b6c5 A difficult choice. 12. a2a3 Preparing the break on b4. 12... f6d7 Preparing the f7-f5 advance. A natural move and a theoretical novelty. 13. e2e4  13... f7f5  14. b2b4 White has a small advantage here, which is normal in these pawn structures reminiscent of the King's Indian, but Black has his chances and the position is unbalanced, which I imagine is what Carlsen was looking for against a solid player with a classical opening repertoire like Fridman. 14... b7a6 This is a very difficult move and I'd hardly think about it. Which doesn't mean it's bad, in fact the opposite is more likely when I don't understand a move. But the important thing here is to highlight a moment in which Carlsen plays in a different way than almost all other chess players. 15. d1d3  15... a6c8 It takes a lot of class to bring the queen to d3 and then return the bishop. 16. c3a4 This move looks a little weird before finishing development, but it's perfectly playable.
