That is the Yelling Defence, Spitting Variation. Leads to very temperamental though somewhat one-sided exchanges.
Gurkesh is 16 years, btw. The tournament is not going well for Carlsen, and its not his first defeat there, I think. I have not seen the match, but I read that Gurkesh won because Carlsen oversaw something very simple and made a big mistake. He tried to recover from it, but failed, gave up short time later. Since the mistake was done by Carlsen, Gurkesh said he is not too proud of his win, he did not enforce it by his own powers.
Everybody is human. Even a world champion can have bad days. And has. I would not read too much into it. There certainly are reasons why many players call Carlsen the probably strongest chess player ever so far.
And I heard that being said before about Fisher. Then Karpov. Then Kasparov.
Female equivalent btw is Judith Polgar from Hungary, she is the only female who was ever ranked amongst the top ten of the chess world ranking list with far over 2700 ELO at the climax of her career, one and a decade ago. I recall that she palyed only two or three women'S chess ptournmanet in her entire life, then said that she wanted to learn formt he best chess palyers, and that were all males. Since then she only played in non-all-women tournaments and thus, almost exclusively against men. Thats the real spirit! She has two older sisters who all played chess as well since childhood.
