It makes sense to trade the dark-squared bishop which is often a  problematic piece in these structures. Especially if White closes the  center with d4-d5. 14. f3g5 Firouzja prevents the idea of the world champion. The position is very rich in content. A lot of moves make sense. 14... c6d8 A nice maneuver. 15. c2b3  15... d8e6  16. h3h4  16... a8d8  17. c1e3  17... h6g7  18. h4h5  18... g7h6 Carlsen is never shy to make the maximum out of any situation.
