What's the difference between blitz rating and elo rating?
Is this sites rating system any different from the system which says Kasparov = 2851?
Chess rating system
Sort:
Blitz is a certain category of chess games, and a blitz rating is ratings for just those games. Elo is a method for calculating ratings. So blitz games could be calculated with the Elo method, and the rating would be both a blitz rating and an Elo rating.
Kasparov's games are rated by FIDE, which uses the Elo system. This site uses the Glicko system. Furthermore, they are different pools of players. Ratings are only relevant within the pool of players being rated.

2 months ago a scientist was working in a lab. Him and his colegues where creating a biological weapon, a being of some kind. It grew from a gel in a jar to a 7ft creature. It killed two of them and was killed by the third. It’s heart rebooted and it fled. Now youtube has become hooked up to it’s brain. It’s coming for anyone who reads this. If you want to save yourself you must copy this to three OTHER videos. good luck!

I wouldn't say they are the same scale. That seems to imply an objective standard of measurement, which doesn't exist here, at least for the ratings. What is the same is the scale of the differences: a 400 point rating difference between chess.com players is going to mean the same as a 400 point rating difference between FIDE players, in terms of the expected results of the game.
I am new here, played 2 games, lol, won them, have a high variable cause I have no stats really, but the thing is I probably won't play any game less than 10 minutes or so cause I have a slow brain. It might be a good chess brain or it might be aweful, but I like to have fun visualizing well if I do that, that will happen, but if I do this..... Speed chess is sort of like checkers. I don't understand why anyone would play chess so fast they couldn't have any fun thinking, lol. Well after 50 games or so on here I will believe my rating a bit more.

Yeah, I think you are right. But what does 400 based rating mean ? I heared players X1 and X2 with rating Y1 and Y1+400 has prorability of winning 1:9. Is it right? (of course if rating is long term given and spread constant is low etc......).
Any way there are math issues with rating. Sometimes it inflates like US dollar right now. Sometimes deflates. So in FIDE they adjust it like economists according to global inflation and deflation in FIDE. On wikipedia is good article.
Well, with a 400 point difference, the expected score for the higher rated player is about .91 (10/11). I say about because the rating deviations figure into the equation too. If the players are low rated, that probably translates to a 91% chance of winning. But you have to consider the possibility of a draw, which is more likely the higher rated the players are. Then it makes more sense to say that if they played 100 games, you would expect the higher rated player to score 91 points.
Do you have to be a paid member of this site to have a rating. I have played one game and won it, but my rating stayed at 1200 ??
No, you don't have to be a paid member. But not all games are rated. If you check the details section on the game you played, you'll see that it was an unrated game. Your other two games look to be rated, so you should see a rating change when they finish.
What determines if a game is rated or not..Is that chosen by the players at the beginning of the match?
Usually open game challenges are rated. Yes the challenger determines if they want a rated or unrated game.
I don't care much for ratings as this is just a hobby to me. Seem's like they should only apply if you're a pro. Anyhoo, I do wonder about the 1200 thing, I'm pretty sure the copy of Fritz I have (which is quite old) starts you at 900 on rated games.
hey just got kicked out of live chess. im a little new to this and i think i said the wrong thing and got kicked out. Does anybody know a way to get back in. lesson learned..
im atempting to get a highter rating but iv halft it through me creer

In playing my first game on Chess.com, I received a rating of 1200, before I played. Why, and how was that arrived at?

You realize you just called Philidor, Euwe, and Lasker (among others) imbeciles, right?
He is not an imbecile. My non-internet father taught me 10 too. 9 is assigned by chess.com. It's all relative. I've seen a queen look like a mere 1 point. You have too.
How can you find your Rating Deviation? I'm guessing that the default rating range that is shown when you start a new game is based on this. Is it twice your RD (i.e. within the 95% confindence interval)? Or is it something larger?
I just found some people who might be cheating on this site they are
A rating 2943 1 loss 16 draw 143 win
B rating 2936 32 win 1 loss 9 draw
C rating 2933 82 wins o loss 1 draw
D rating 2930 89 win 8 loss 13 draw
So you see that someone is good and then u just make a statement that they are cheating? Proof or go away.!!
