I'm still getting lots of 750-1000 Rated Problems when my Rating is about 1200 -1300 plus .. The More I do,the more of these Very Low/Way Lower  Rated Problems I get .

( Sometimes,it's not even that we make mistake with the Low Rated Problems,we may move the Piece to a Wrong Square n' not the Intended One/Mouse Slip ,and then we lose 40-50 points and go back to Square 1 .. it has happened to me many times )

I agree with benkku52 that to be fair,we should get roughly even number of Higher,Lower and Same ( Around our Rating ,ie ) Rated Problems when compared to our Current Rating.( If the Purpose of TT is for Competition amongst Members ie )

.. or juz Only around our Current Rating ,like maybe 100-150 points above and below it,at any time.

( but I dunno if this can be done,since you can't tell how many Problems we would like to do for each Session since if we are Premium Members,we can do as many as we like )

Or maybe make Tactics Trainer similar to Chess Mentor,where we can choose the Rating Range of our Problems ,if the Purpose of TT is mainly for Educational Purpose ie .

( Although,in all Cases,not all the Ratings of the Problems are absolutely Accurate as they are currently the Outcome of How Well the People who attempted them,perform .. eg,there are 1900 plus Problems which are Mate-in-1 or Hanging Piece Problems and some More Complex Problems can be rated quite low too.)

.. Juz a Suggestion.

Weird. No fix has yet been applied. :)

Up till now Tactics Trainer problem difficulty was predictably wrong. This means that it either worked properly or stuck in a mode of giving problems fixed around 1600 independent of my rating.

But look at this sequence:

Among 1600 rated problems suddenly two 2040 problems pop up just to go back to constant 1600 mode afterwards. What sort of evil randomness is this?

If I'm rated 1850 why am I doomed to solving 1600 problems all the time?

As it is possible in the live game section to set rating limits for the open seek ( how much the opponent can be lower or higher rated than you ) it should be possible to set limits for the problem difficulty in Tactics Trainer.

If I'm rated 1850 I would like to be able to set limits of say -100, +100 meaning that I can only get problems between 1750 and 1950.

Better now, yes? :)

Sadly, no.

It should be problems around my rating or higher? But a lot of times it's a difference of more than a 100 points.

I don`t get the right porblems in the unrated mode. I prefer the unrated mode because under time pressure I often choose the wrong move. So I want to have my time to think about moves. So I set a rating range and save it. But I am getting only problems arround the 1200 and not in the range I was asking for. I worked fine about a month ago. Why is there an option to set a range if it is not working? This should be fixed!

Currently, the problems keep neatly oscillating in a +/-100 points corridor around my rating, which is how I would expect it to be. Thanks!

I'll observe this further and see whether it changes depending my rating ups and downs.

I've broken the 2200 barrier and it seems that the samples from the puzzle pool in this rating region are quite stable now.

Great news! And, yes, we are looking into the new issue with unrated puzzles + a configured rating range right now.

Yeah,the Rating of the Problems I'm getting seems to be stable ,about 100 points above and below my Current TT Rating now .( but not sure if my rating were to drop further ,like before,tho )

Thanks Very Much for the fix !

How about not letting unrated puzzles affect a player's rating?

Let a puzzle get a virtual rating and only after 100, or so, attempts will it get a real rating.

Today, out of 25 problems, only 3 were higher and 3 equally rated.

Maybe this is part of the usual fluctuation that will be balanced in the long run, but currently, it's definitely too early give an all-clear verdict.

Folks, also see this thread about broken unrated TT: 

http://www.chess.com/forum/view/more-puzzles/tactics-trainer-broken?

Its kinda related I guess. I hope they look into it, as I find it very annoying. I wonder what they did...

Please keep us updated on the progress there. Right now it is really most annoying, especially since it was working perfectly until maybe 5 days or so ago. Thank you.

We should have provisional ratings for problems. Or like FIDE ratings, only after a certain number of attempts does the problem get rated.

I am pleased to see that improvements are in hand for TT, it is an important element of the site for a large number of customers.

Looking forward to the results.

I notice today while working in practice mode of tactics trainer that it is not allowing me to choose the problem range.   All the problems presented to me are around my tactics trainer rating, regardless of whether I choose a range that is above or below my rating.  After completing a problem it still tells me "practice mode, no rating change."

The ratings range of practice mode used to work, but I haven't used tactics trainer for some time so I don't know when this problem began.   Hopefully it will be fixed soon.

Big Hickory, you are experiencing the same "unrated TT" bug that a bunch of others including myself are experiencing since last week. Not that this is any big consolation, of course...

I hope chess.com realizes that we are paying members and they resolve it soon. I am somewhat annoyed because before introducing any supposed "improvements" to the TT (which is generally welcome of course) they should first of all test whether the new software messes with the existing features. This is bad project management.

Update: It seems they made changes, and now the "unrated"  is working normally again (Tuesday, 12/03/2013 16:31 EST)
