Why chess.com game review elo estimater is RIGGED

Sort:
8-on1

I as a 700 on rapid have wondered how people get such a high estimated rating. I dug a little deeper and figured out its not our play that is bad. The elo guesser is partly based on your opponents rating. I played a e4 e5 nf3 nc6 game with martin and got a average rating of 1300. when I played the same moves against the magnus bot I got a average rating of 2600.

game against magnus, 2600 estimated rating and game against martin, 1300 estimated rating

Yes. The same game moves are estimated differently because this rating estimate takes into account your own rating as well as the opponent rating.

chess.com has already commented how this rating estimate is not too great yet. It is a work in progress, but we are far from the point where computers (game report) can accurately predict chess rating from an individual game. If you want to see a human titled player predict ratings based on a single game, then check out IM Levy Rozman (GothamChess on YouTube) with his GTE (Guess The Elo) series grin.png

The accuracy system is juiced too.

The question to chess.com:

Hello,
Question for chess.com:
It is in the interest of all players that the analyzes of individual games are based specifically on the moves made in the game in question and not on the previous rating of the players.
For example, why the estimated rating of a single game 
depends on the player's previous rating. 
The higher the previous rating, the higher the estimated rating obtained from the individual game.
The same question also applies to the assessment of the accuracy of the game.
I think that every player would like an honest and correct assessment of how well or poorly they have played in a single game.
In other words, the moves made in the game would be determined by the individual rating, and would not be affected by the player's previous rating at all.
Is there a change in the matter?
Thank you for your reply in advance.

Hello!

It’s interesting how the estimated rating can vary so much based on the opponent’s rating. Your discovery highlights that the Elo guesser takes into account the rating of your opponent, not just your moves. Playing the same disneyhub opening moves (e4 e5 nf3 nc6) against Martin, a lower-rated bot, gave you an average rating of 1300, while playing against Magnus, a much higher-rated bot, resulted in an average rating of 2600. This shows that the context of the game significantly influences the estimated rating. Keep this in mind as you continue to improve your skills!

Yes but not 2 moves into an opening.

In my opinion, the estimated rating of a single game should be exactly the same regardless of the player's level if the exact same moves have been played.

Entire Game and system is rigged, Over 99% of players are stuck perpetualy at low ELO, it is Outrageous, What other game has this? See now? My dear friend ELO is Terrible and Arpad Elo Invented Most opressive System In history, You cant Win.

I meet up with some friends. They play chess games with me. (I don't have em added on chess.com because I like to play friends in person with a board) And they show me their 400-700 ELO and I beat them most of the time. Keep in mind I'm 200 in rapid.

They are kind of broken

If the rating ranges are really close like that it'll be even but if the difference is like 100+ ELO the person with higher ELO is gonna win most of the time

What's indicated is nonsense, some complicated game when I play, I get 700 elo strength, and I compared with another flat position, when I blundered my knight, resigned and got 1500 elo against 1600 when he played perfectly.

Lol

what if you never plan to play anything but bots? are you still gonna say playing humans is better to train you to play bots better?

ItsTwoDuece

well yes, its based off of your opponents rating, but this only has a prominent affect on the outcome if you guys don't play any moves outside of book. Try to do the same thing with a game that lasts 70 moves and has all the same moves- assuming near perfect play, the elo estimations will be a lot more similar to eachother. You just didn't give the algorithm any moves to work with, so the only thing it could base it on was current skill.
