Rated Puzzles giving me a minus even with the official solution?

Hey everyone,

I was just wondering if anyone else is experiencing this lately...

I’m not currently in the beta testing group, but something weird happened today. I was at the top of Rated Puzzles this morning with 65,535 — and now I’ve dropped to 63,793. The strange part? I’m still getting the official correct solutions. No alternative moves, no inaccuracies (as far as I can tell), just doing what I normally do. Yet I’m being penalized with a minus rating even when the puzzle says “Correct.”

I don’t recall making any mistakes or misclicks. Has anyone seen something similar lately? Is there a new system quietly rolling out that explains this? Or could it be a bug?

Would love to hear if anyone’s got some insight.

Cheers,
@JosephReidNZ

i'm not sure about this even though I'm in beta, but maybe move this to help and support? it'll probably be more likely that a staff sees this and answers you

It's a very good chance you were at the puzzle limit the value is overflowing.

It happened to me last time with this puzzle:

https://www.chess.com/puzzles/problem/1959820?

I did it right and chess.com still took me 15 points. I checked it after finished to resolve the 3 rated puzzle/day (I don’t have a subscription), and my moves were right, still the site engine said my move was wrong. I think this happens because I don’t accept all their cookies. Chess.com wants to use my info and if I don’t want to accept, then they penalize me, by stealing my rating points, despite my correct puzzle resolutions. I accepted the Functional cookies, and other times the Functional and Performance cookies, still this points stealing happens. Apart of this, when resolving the rated puzzles, the page keep reloading making difficult to see the solution. I wrote messages to CHESScom explaining the situation and asking for an answer, but they didn’t provide any. I think I will delete my chess.com account and leave this bullying-business site.

No. My Puzzle Rating is 2642, I do not have a payed subscription, I only have the right to 3 rating puzzle per day, and the second puzzle I did the right moves, still the chess.com engine evaluated it wrong and took me 15 points. See my post above. So what “overflowing” are you talking about in my case? This is deliberate behavior against not-paying subscribers, who do not want to accept all their cookies, stealing and using personal info. This site is built on these many non-paying accounts and now the owners got greedy. They not even bother to respond to inquiring messages (CHESScom), because they know what they are doing.

Good luck with that. I wrote to CHESScom explaining these problems (see my messages above) and they didn’t answer. You either pay a subscription, or accept all cookies, so they make money with your personal info, or you get robbed of your Puzzle Rating points. WILD CHESS(com) WEST. Bye 👋 Chess.com 🍌

I've just contacted Support to see if they can get a 'rating refund' for me,

brave statement saying you are better than an engine. No, you are wrong and Stockfish is correct. I used to feel that way too, and I found out why it didn't work after the puzzle. Also, it is unfair to blaim Chess.com in this situation. They have done nothing to harm you or your account. This is also irrelevant to the topic, and I am only adressing this because of such a ridiculous claim.

The post you were quoting was specifically about a situation where the member was at a rating that is most likely the maximum value. Overflow is related to overflowing the highest value and can result in unexpected results depending on how the code is written.

Regarding your particular situation, if you used a hint, or accidentally hit the hint button, then the problem is considered wrong even if you get all the moves right.

I got over this situation. But from what I remember I didn’t hit the Hint button (I know exactly how it works). I just did the right move and BAM -15 points, than I checked the same puzzle as unrated, and the same move was deemed correct.

Moreover, in Puzzle Battle, I check my mistakes (wrong puzzle), but also of my adversary, and a few times, the same good move I did, evaluated right for me by the engine, was evaluated wrong for my adversary and he lost a point. I even write a message to an adversary telling her about the puzzle evaluated wrong for her, but right for me (with the same move). There must be a bug that cause this problem sometimes.

I’m sorry if the problems reported by me, have nothing to do with the problem discussed in this thread.
