Tactics Trainer Rating inflated

SheldyM
Is it just me or have the tactics ratings become a bit ridiculous? I’m almost on 2200, but online I’m usually around 1700 in rating. Have they made things easy just for us to feel like we are improving?? I saw some very simple tactics rated at 2400 the other day. I feel like the 1700 tactics on chesstempo are the same strength as the 2200+ rated tactics on chess.com?

Idon’t Know, but best players have a rating of 5000 in tactics, so I think like you.

1. They have added new tactics recently, so the rating of those tactics will adjust in some time. 

2. The rating of tactics depends on who gets them right and who gets them wrong ,so they adjust accordingly. 

3.Tactics trainer ratings are only a predictor of your tactics strength not your playing strength.

nah TT is a complete Joke

I have a hypothesis that the large number of users who cheat at tactics trainer have inflated the ratings of some problems. Solving these, naturally, will increase your rating.

Earlier this week, I solved several tactics problems with ratings over 2500. They required imagination and calculation, but two students (rated under 1200) mostly solved them yesterday when they were looking for forcing moves.

Also the fact that some people take a lot of time on problems while others solve them fast, the former group always have higher TT ratings compared to their peers of same playing strength.

A week ago in one of the forums, some poser attempted to shame me because my tactics rating was only about 100 above my blitz. His blitz is 1700 and tactics over 2400. A quick glance at his history shows 70% solving success and an average time of 20 minutes per puzzle. I think it is likely that he is getting help—maybe engine help, maybe only moving pieces on a physical board. In either case, such jokers who game the system inflate the ratings of problems.

I tried a few of the problems he failed. They were easy to me. He failed them because he did not spend his accustomed 20 minutes.

He may not be getting help but taking 20 min on a puzzle is a guarantee to increase his success which in turn puts his TT rating much higher compared to his peers in the same rating.

Agreed. His other behavior, however, arouses suspicion.

Cool story

Yes, they're very inflated, I noticed this too. Sometimes I see very easy problems (problems who are good only for people who just started to play chess), like mate in 2 or unprotected piece, rated over 2000.

Look here.

Mate in 2. Guess its rating.

I tell you. It's 2475!!!!!!!

Take a look if you don't believe me, problem number is 136708.

A friend of mine asked me to look at one of his recent problems. So I tested it. It was FORCED moves since his king only had one square to move to. For 3-4 moves. Problem solved and he got like 15-18 points and it was 2100 rated. But there was no other moves. So it should be 100 rated.

Puzzles sometimes get modified and I believe the rating stays the same. So, a problem that used to be harder, may now be much easier and it may take a while for its rating to adjust, especially if it is higher rated and only higher rated players get it.

 

Also, some problems may be harder to solve with all moves correct, but the first couple of moves are fairly easy. So, lower rated players may get the initial moves, gaining rating and causing the tactics rating to decrease.

 

If there are serious problems with a tactic, it can always be reported. Not sure if they would modify a rating on something like the forced moves one, though they might just remove it from the trainer.
