You are new to the site and you still haven't taken the trouble to read the TOS apparently. Cheating is not to be discussed in the general forum, but in the cheating forum to which I provided the link. Also, nowhere in the site are you supposed to accuse a specific username of cheating in public, but post a complaint to the site directly. There is a detection system in place, and many people did get banned... whether this is sufficient is debatable. But at least you should know what you are talking about, and where.

 If this is true, and I am not arguing that it is not, then Chess.com has players rated 500 to 700 over what they would be otb; actually I think this maybe the case which if applied to me, I would be around 1200 to 1400 otb which sounds about right to me. What I think really makes a mess of the whole internet rating is that people do cheat and use computers to play for them and thus earn a rating that is not true, which then brings up the average ratings up over where it should be. (Let's not argue about the cheating because that's not why I'm posting here, and we all know it happens, that is why people get banned; anyway, I wish people would just play and have fun and not use engines to have to beat people just so they can feel good about themselves as it proves nothing). Maybe the question that should be ask in relation to how inflated the ratings are on this site compared to otb, is...should there be an adjustment made to the current ratings of all individuals on the site to make it more in line with otb ratings? Like they did with womens ratings once, they added 100 points to everyone elses ratings except for Judit.


That's almost a fixation with internet chess ratings. Who cares about them? Maybe it was a mistake to make them in the range of FIDE ratings. If they were between 0 and 300, I think that no such discussions would take place.

 I am not directly accussing any individual of cheating, but it has happened and it does go on; yes, there are measures taken against cheaters...As far as internet ratings being a fixation, I think it's more of people wanting it to be right or as close to something they know is the standard, whatever that may be (FIDE, USCF, etc...).

If my true Chess.com blitz rating is 1500, what approximate USCF/FIDE can I realistically expect to have? Will it be lower or higher?

Blitz is just so much different than blitz. But here on this forum we have come to the conclusion that our chess.com CC ratings are about 200-350 more than what we can expect our USCF ratings to be.

So my rating would be like 1200 USCF? What about my FIDE rating?

By the way, thanks for sparing me the depression of finding out a posteriori about my USCF rating.

They don't corrolate at all. OTB is almost 99.99% lower. A person rated 2100 chess.com is about 1800 USCF

Then in that case Chess.com ratings need to be fixed in order to reflect the real thing. Surely noone would have thought that the higher our Chess.com ratings the higher the likelihood we would keep coming back to this site.

Online chess and OTB chess are two different things. Of course rating system would be a lot different. Plus you've gotta remember people playing poeple MUCH LOWER than them

Another thing is that the average USCF player is much stronger than the average Chess.com player. That's kind of obvious given the fact that anyone who goes through the trouble of joining USCF is likely a more serious chess player than the average recreational internet chess player.

1200 is supposed to be the middle of the road rating for both chess.com and USCF (as far as I know). So it really just depends on the players as to how valuable each rating pt is.

Nope. Elo's system assumed a mean of 1500 (I believe Glickman did not alter this assumption). The USCF mean and median (excluding scholastic players) is near 1500 according to the latest published data (several years old).

Chess.com's mean is closer to 1200. Most ratings of players in both pools are higher in turn-based here than in the USCF, but lower in live.

Ty for the clarification. I'm hardly the expert; I have no rating! But I thought it must be lower.... 1500 just doesn't seem THAT mediocre Innocent

Average is not supposed to be mediocre, although sadly often it is.

If you look at the bell curve when you select "players" for online chess, you can see a very very drastic drop off around 2000 as to the # of players above that rating. That would make me think that the higher the rating on this site, the more accurately one can predict the USCF rating.... Or I could be wrong again Wink

I would very much like to get over 2000 USCF. I'm hovering around 2100 in turn-based here, but there are players over 2700 here that are lower 100-200 and sometimes much more than me in USCF. I am able to maintain live chess ratings over 1800 here only when I play infrequently; when I play more often I accept whatever challenges are available, and then score a mere 60-65% against players in the 1500s, which drops my rating.

So, I don't see much correlation. But it may be that those few that are 1000 higher here than OTB are the exceptions, and that with a difference of 200-300, there is a strong correlation at levels above 2000.

I agree about a strong correlation amongst the higher rated people. But I also think we've failed to take into account the strength of challenges people take on. Someone with equal strength to a 1800 could get up to 2000 by only playing people 1700 and consistantly getting a result Laughing

Right, Such I am 1300s uscf rating but I am only 1300 live chess rating. Cause I hate fast game!!Laughing

Try comparing your percentile of rank here to your percentile of rank within USCF.  i.e. if you are in the top 10% of players here, find the point where the top 10% begins in the USCF, and you will know your rating is at least that number.

Not true. The percentiles are dramatically different from one pool to the other. I am in the top 10% USCF but the top 2-3% here and nearly every other website where I play. Two exceptions: at another turn-based site, my percentile score is very close to my USCF percentile. At the Playchess live server, my percentile score runs closer to the top 1/3.

These differences probably stem from the attraction of each playing venue to casual, and thus weaker players. Those that invest in expensive chess software and/or annual membership fees are more serious (Playchess) on average than those that play, often for free, at a website such as this one.

I suspect that the top 10% here correlates to the top 30% USCF. It takes a higher commitment to the game to play in USCF events than it does to gain a rating here. More weak players are culled from the pool.

My OTB rating is 1816 uscf, although in all three of the tournaments I played in this year I have posted 1900+ performance ratings. My online rating here is 1994, but it's still rising. Since I came back to this site a few weeks ago I haven't lost a game, so it's gone from 1668 to where it is now.When I played a few years ago I stayed around 200-400 points above my uscf rating, so I think that is probably the right adjustment. However I usually don't use databases or anything like that.

My live chess blitz rating has stayed in the 1880-1900 range pretty consistently for the last few weeks, which I would estimate is my actual playing strength in uscf.

My bullet rating is 2037 but I don't really play any bullet because my wrists aren't so good.

My tactics trainer is 2610, which makes sense since tactics is the strongest part of my game and usually how I win my tournament games against my strongest competition.

 

So I would conclude live blitz ratings are what correlates most strongly to uscf, atleast in the mid range of the ratings.
