Ah. I think the meaning was clearly relative to the level of play and you took it too literally.

That’s incorrect. The original poster said Nepo lacks the mental endurance required to be world champion, not that he lacks it altogether.

He lacks enough of it to become one at this point in time (when we have Magnus and Nepo has his current mental edurance) :)

Actually relative strength is one of the things that wonder me the most I would say in the game: when one of the opponents is much stronger than the other the wins look so easy and the loses so stupid, but when the winner is matched against someone even stronger you see the same exact picture. I love you all I dunno why I say that now but here you go.
