Ok, so HOW ARE THE PUZZLE RATINGS SO FLIPPING HIGH?!?!?

Hi guys! Just wondering: Why are the chess puzzle ratings so high? My puzzle rating is about 2/3 times my game rating, which I think is normal, but players like ALYURFED (https://www.chess.com/member/alyurfed) have 10,000+ ratings (this guy has like 65,000 puzzle rating!) How is this possible? Are they hacking, or what?

They just do a lot of puzzles.  Alyurfed has done nearly 80,000.

You have done nearly 3,000.

Do another 77,000.

ALYURFED's rating as of today is 65535, this happens to be 2^16-1 which is the largest 16 bit unsigned integer. Seems like it's the highest score possible, definitely a bot, imo.

The potential points loss at those levels is pretty unforgiving. Looking at el008's profile, who has ~46k points, if they get one 4000 point puzzle right, they get 5 points. If they get one wrong, it's -440 points!

Alyurfed is a bot, but I can't prove it. Regardless, Chess.com doesn't have the gumption or will to investigate.

I also wondered this. I would vote for Chess.com to fix this, as I enjoy tactics and puzzles.

As to why, I have a hypothesis: Chess Tempo does not seem to have this problem. It appears that Chess.com puzzles always award +5 minimum for each correct puzzle performed, regardless of ELO ratings (player ELO and puzzle ELO). This indicates they are not using ELO formulas. Chess Tempo uses ELO, and it is the player ELO vs. the puzzle ELO, where each are adjusted. It appears Chess.com has puzzle ELO that adjusts, but it is not used to "correctly" adjust the player ELO.

If I were to defend why Chess.com does this "incorrectly," I assume it is due to the feature of awarding partial points for partial puzzle solves, and the difficulty of applying an ELO formula in a partial way. Not sure though, as I can think of ways to do this that are not too hard.

Anyway to get Chess.com to comment?

The site used to penalize players for taking too long on puzzles, but have moved to puzzles giving at least 5 points as long as they are solved correctly.

One idea would to do both: Allow infinite solve time, no penalty, but also implement the proper ELO calculations on both player/puzzle.

The puzzle system is designed to give more points the faster a puzzle solved, based on the average and less the longer it takes. I think the max is based on the Glicko rating system, though it's possible the average one is and bonus points are added for doing it faster. 

 

That said, the system just has to be able to provide puzzles of sufficient complexity to be a challenge. It doesn't really matter what the ratings of players end up being.

Do another 77,000.

You're naive to think that a human alone achieved that score with 90% accuracy

Idk

i hit 3600 with 67% accuracy so far... my goal will be at least 5000 eventually.  🙂

In chess com there are a lot of freebies and puzzle ratings seem to be very loosely correlated to their difficulty. A simple checkmate in 3 could be 2600 but then a tricky quiet move might be only 1700.

Puzzles get their ratings based on being solved or failed by members. It's essentially treated like a game against a player of a given rating.

they memorize puzzles and get them right, cause as you get higher and higher the number of puzzles decrease

If it is 2/3 times the your rate, doesn’t mean that it is lower lol (I understand what you mean though)
