13. Nh7! 13. Qh5 Qe8! is nothing special for White, so Carlsen does not hesitate to give up a Knight for the initiative. 13. ... Re8 14. Nf6+ gxf6 15. Qh5 e4! 16. Re1! f5? This may be a mistake worth a double question mark, but defending such a position would probably require a classical time control. 16. ... Bf5 followed by ... Bf5-g6 offered better chances of holding on. 17. Bxh6+− Nxd5 18. Bg5 f6 (18. ... Nf6 19. Qh4 Re6 20. d5+−)

In his ChessBase report Klaus Besenthal says that "Die unbestechlichen Computer halten hier 14.Bxh6 für den besseren Zug." See https://de.chessbase.com/post/magnus-carlsen-invitational-erstes-finalmatch-endet-unentschieden

16. Re1! Leontxo García (El País, 21 de marzo de 2021) escribe que "la idea de So era 16.Bxe4?! f5, y lo mejor sería 17.Bxh6! fxe4 18.Bg5 Bg4! 19.Qxg4 f5 20.Qh5 Qd7 21.Bh6 Nxd5 22.c4 Qf7! 23.Qxf7+ Kxf7 24.cxd5 Bxd4, con ventaja negra."
