tactics trainer


ok. we found a REALLY big and nasty bug. jay will work on fixing it as soon as he is uncurls from a ball on the floor where he has been crying for the last hour. we'll get it fixed and then script a fix to everyone's ratings.
if you read this, send jay an encouraging message ;) he'll need it today :)


Out of curiousity, is this the average time of users that solved the problem on the first try, or just the average time of all users on the attempt in which they happened to solve it? I'll often get a problem only after failing it a couple of times and usually quite quickly at that (as by then I have some good insight into what the solution isn't). If these are included in the average then I would expect that it is actually understated compared to what it would be if it only considered those who solved it on the first try.

Average time to solve a problem is calculated or adjusted only when a user passes a problem on their first attempt.


I was'nt making any grand achievements but now I feel like I just started playing chess, I cant see any clues I'm lost... rating plummeter too


The other thing that would be nice is if the "Show Solution" button would work repeatedly. Right now, it only shows you the proper sequence once. If you want to see the sequence again, you're out of luck. Bit of a bummer, as the point is to drill these patterns into us by repetition.
But let me be clear that I think Tactics Trainer is wonderful, and a huge argument for upgrading to premium membership.

A few points:
1) Jay, you're the man, the frickin' man
2) I love the Tactics Trainer and want to give my thanks to Jay, Erik, and the rest of the staff who have fielded such an excellent (and fun!) resource.
3) I did a mate-in-7 problem last night that was only rated at 925. What!?! Anyhow, I'm assumed that Jay's miracle bug fix corrected the problem.
4) I'd like to have the option to turn the timer off, not get rated, and just evaluate my progess based on a pass/fail ratio. A story about Fischer--perhaps apocryphal--runs like this: a friend asked him how to improve his chess game, and Fischer replied, "Throw away the clock." Basically, that's what I'd like to see on the Tactics Trainer.

thanks for fixing the problem JAY :)
1600 at your adjustment, then lost 300+ points, Now, could you fix me?!?

It would be good to have the option to disable the rating and just have a timer to remember my speed and compare with others.I don't really care about the rating,but about time.
It is not obvious at first what is the goal in every puzzle:win or draw?


The only gripe I have about tactics trainer is that there are some cooks. One problem had a 2-move mate from a certain point in addition to the solution (also a 2-move mate). I also have a slight problem with penalizing something which is technically winning (perhaps win of queen) while missing checkmate. There should be partial credit for those. (For example perhaps I won the queen, someone else delivered checkmate, but the third person blundered a knight - how should I get the same score as the person who blundered the knight?).
All in all, a great product. But - if I were a paying member I would spend too much time on tactics trainer. I guess that is ironic?

I think the tactics trainer is great, it is really starting to make a difference to my play. I think that the timer is a great idea as it really forces you to look deeply into the problem.
As for the difficulty, doesn't the type of problem adjust itself to your rating anyway?
Keep up the good work guys
Cheers
