What Kind of logical fallacy is This?

between 2 Debaters.
A Debater is making logical statement,
But another one B is keep talking about his fame Like " I write blogs,I alone counter other Blogs when it comes to debates I am master at Debating,You never did 10% of my work,So I am better than you everyway. "
I mean He keeps talking about his fame and saying that he is better than A in everyway because he has successful in his life.Famous for his beating others in Debates.
What kind of Logical fallacy is this?

Sounds like Appeal To Accomplishment: https://www.logicallyfallacious.com/tools/lp/Bo/LogicalFallacies/19/Appeal-to-Accomplishment<>

Dr. Bennett's answer is correct.
The general idea is that being successful in one field doesn't make you good at something else. If I am successful at business, that doesn't mean I'm also a great musician. I can be a great debater, but that doesn't make me an expert in every subject.
Also, this argument diverts from the issue. Anyone can be wrong about anything, even an expert.
If you are interested, Plato's wonderful dialogue Gorgias discusses this fallacy at length, especially in the first several pages. Socrates criticizes Gorgias b/c Gorgias is skilled at persuading people to believe things about topics that Gorgias knows nothing about.

While person B is clearly making an Appeal to Success - without knowing what person A is claiming we cannot know whether B's response is a bona fide deception and not just a braggadocious tirade. While it is indeed a distraction (Red Herring) simply boasting about one's credentials and experience may be delusional, if not, obnoxious, but not necessarily an error in reasoning when considered out of context.
