Using chess.com's game review on a game like this is just a joke. The players have probably analyzed the game deeper at the table than the weak engine here.
Magnus wins with 2 brilliant moves
Sort:
15 Bf4 is a novelty.
16 Na3 looks worse than 16 Bg3.
22 Bc2? loses. 22 Qc2 is equal.
It is not black's moves 21 and 23 that decided the game, but rather white's 22nd move.
Carlsen vs Caruana in Tata Steel, Magnus wins with 96% accuracy and brilliancies on moves 21 and 23
