" Beginner " players playing above their rating
Maybe I'm just not caught up well with the Internet. If the situation has been addressed and I don't know, sorry.
There is certainly some cheating and sandbagging. However, there is also a simple statistical concept that may help explain the perception that so many low-rated players are underrated.
online blitz and rapid ratings are highly variable. It is common for ratings to fluctuate by 200 points or more.
Consider a player with a rating of 500. This rating may be accurate. It may be an overestimate of someone with a lower skill level. Or it may be an underestimate of someone with a higher skill level.
Which of these latter two possibilities is more likely? That the player has a higher skill level! Why? There are many more stronger players who may be underrated than there are weaker players who are overrated!
Thanks for responding. I think I get it now, and it seems like I can't do anything about it. Well, we Beginner players will just have to work extra hard. ( mikewier ) Once again, sorry, I do not know how to do the response text. And, from 600 to 1200 is still quite a big jump of skill level. ( heathrowairport6 ) appreciate your responses!

Do you have any proof for that?
(The answer is no).

Yeah… just no.
For those who say that there's no proof, just go back to playing with 500 elos. They literally make no blunders. Sure, you can beat them. But do a game review, the game review will normally say they played like a 600 - 950 rated player. And, someone with 600 elo can beat 2000 elo players occasionally and 1300 elo players consistently.
