Tactics Trainer Problem Difficulty

I like the interface on TT 

At the moment I am still prepared to wait for improvements, which are promised

Is anybody else having problems with TT ?

I am using Firefox and when I attempt to make a move it resets the problem, it will not respond, but the clock is still running ??

just done it again

and again I give up

To be fair this was my problem with some Malware that was playing havoc with my PC took me 2 days to sort it out.

Apologies Chess.Com

It won't give you puzzles your rating you have to go to settings and set a rating range

I documented the subject of this thread ad nausem three years ago.

  Glad to see a little progress.

Once again Tactics Trainer has me tearing my hair out.

13 correct 2 wrong net gain 40 points an average of 3 points per solution so to move up 100 points I would need 33 consecutive, no time penalty correct answers.

When you take into account that many problems have alternate solutions just one move longer, the whole thing becomes demotivating and time wasting. I simply cannot progress to newer tactics.

I feel like Cesiphus chained to a rock, doomed by the gods to push it uphill only for it to roll down again.

Please look at this or lose another Chess Fan.

It also should contain an element of motivation to train

I renewed my last membership on the basis of a V3 fixing these problems, I am still waiting

Konowing that there are titled players among the solvers, has actually helped me to disregard a problem's rating. If you wanna practice forks, pins and discoverd attacks you have to set the trainer at approx 900.

I'm already winning much more games against local friends OTB, so at least something good comes out from doing the tac trainer

Same problem for me since today, a lot of 1400-1500 tactics when I am 1900 rated.

Very annoying.

Is there something that can be done ?

Thanks for the tip, I will try that. That doesn't mean I will lose my current rating right ?

Actually I get more than +1 if I play fast enough. But still, you are never never quite sure if you play against a difficult or an easy problem and that is stressful. Interesting though. But weird.

exactly, thank you for your answer 

These are the symptoms of a database which MAY not be enough furbished in high-rated problems. If there were many problems rated 2000+ and these problems are delivered often to a player rated 1870 like you, you would have a possibility to increase your rating at a normal pace (of course, if you are able to solve them).

One possible way to increase the number of problems is to use data mining to identify and retrieve problems from games played on chess.com. With millions of games played, this should solve the issue.

Yes, Heler, I'd agree especially when someone as benkku who has already done 36000 tactics trainer problems experiences such things, he will have seen already a significant part of all the problems in tactics trainer (around 50000...60000).

This would mean that one way for him to fix this himself will be to simply resetting his TT history ... doing some tactics again that he saw 10000 problems ago will often be interesting again, and it certainly can be interesting to have another try at roughly all that half of the problems he had not gotten right so far.

Your idea of mining has been implemented and used ... this is one of the reasons why chess.com has been able to build these tens of thousands of problems in tactics trainer :-)

I had a tactics trainer problem rated 1536 compared to my 2063 rating today (527 rating difference). I have not played nearly as many problems as benkku (2800 compared to his 36000) and it was only my fourth problem this year. I don't care much about this for myself and maybe it would get more common for me the more tactics problem I play, but I think I should be nowhere close to experiencing this yet (unless occasional much lower rated problems is intended).

And if it is a problem due to many tactics problems played, then maybe the algorithm should get changed to avoid getting paired with their last 1000 problems played or something similar (instead of all problems played). Chess.com asking their users to delete their history does not sound like the best solution to me.

MartinO, the thought of resetting history is only for users with extremely many problems seen, of course.

If chess.com has recently been doing some changes to how tactics trainer works, then this can of course also be an effect.

Tactics trainer ratings, both of tactics trainer problems and of tactics trainer users, are some kind of intricate feedback system, which is likely to need some time to settle to a new equilibrium when there has been some change about how exactly tactics trainer works.

One of such possible changes is about details of rating adjustments, such as whether or not solving a problem correctly using a lot of time will or won't lose rating points (some users had been wishing there should not be any points lost, which of course means a huge change about how the system will work), another is about how frequently a tactics trainer problem is taken out of tactics trainer from the rating it had reached and reinjected at some standard rating such as 1000, 1200 or 1400.

the thing i think is utterly stupid is when a tactics problem has more than 1 correct answer , but the algorithm is set for only 1 right answer.

    Chess.com cheats too, and thats how.

Amplepawn, chess.com has put a great deal of work into fixing or removing such defective problems. If you have found any such defective tactics trainer problem, could you name it (give its ID number or link), so that it can be fixed or removed? There should now be so extremely few of these left in tactics trainer --- your help in finding any remaining examples will certainly be appreciated.
