I saw Anish Giri’s remarks about Magnus Carlsen’s resignation on move 2 against Hans Niemann during the live broadcast, but you can find them without searching through an hours-long broadcast with a click here. (HT: Ervin Middleton)
If you scroll down a bit, you’ll find links to many more hot takes on the subject (e.g. Hikaru Nakamura’s, Levon Aronian’s, Shirov’s opinion about Niemann’s final GM norm(!), and plenty of others.
It doesn’t look like this issue is going away any time soon.
