Why did Chess.com raise all our ratings recently?

Everyone's ratings went up about 200 points overnight.  What happened?  Does anyone know?  Thanks.

I didn't get that... I don't think so at least.

What rating? Stardard, multi-day. bullet, blitz?

Standard.  I mean "recently" as in within the last several months.

A titled player was having trouble breaking 2000 on this site and complained vigorously and with effect.  Erik decided the standard ratings were too low and gave everyone a raise in their standard rating.  This has to be at least 3 or 4 months ago.  There were half a dozen threads on it.  You could look it up...

So basically I've lost 200 points since then?
Because I sure as hell haven't noticed anything.

Okay thanks, B-Dogg.  I could look it up, sure.  Do you have any suggestions for search strings though?  I'm not very good with that.

And here is the announcement and main thread:

I think it was a good idea.

When I came to chess.com I assumed that the ratings were roughly commensurate with USCF ratings (my last rating was 1729), then I lost a couple games to 1200 players and had to recalibrate my expectations. I did better after that.

In terms of math, ratings are just a game that arrange players in a pool in rough order of skill based on results. There's nothing magical about a 1200 or 2000 rating. Those numbers could be anything and still provide a valid ranking within the pool.

However, in the real world we do have expectations of how strong players are at various ratings. Thus the need for chess.com to tweak the system in the hope of aligning chess.com ratings more closely with what we expect of those numbers in USCF or FIDE.

They won't be entirely successful, but they can do better.

Lunacy.

Chess.com has also switched the name of correspondence chess played at traditional time controls, but using a website for move transmission (rather than telegraph or postcard) from the illogical "online chess" to the equally nonsensical "daily chess". 

 

I mean, who doesn't play chess every day, right!

And yet most lower-rated players I know, including myself for a long time, had higher standard ratings than blitz or bullet, before the rating increase.

Wait. I haven't yet played a Live game, so that means that I'll start at 1200? Not 1400. Unjust.

Did the site lower your rating?

No... I stopped playing standard over a year ago, and since then my blitz rating increased quite a bit.

I had stopped playing standard too, but played a handful of games after the increase. As soon as my RD dropped below 80, I gained a 400 point boost.

However, as a consequence of the ratings boost, there will be that many points more for you to absorb from higher-rated opponents should you defeat or draw them. You will even lose fewer points if you lose.

So it's all good.

It will take a lot of time for the increase in rating to take place. And I won't like to get very easy games for that matter. Cheers anyways!
