2300 rated puzzle?

Should this puzzle be revised?

Depends on the solution, but if it is Qxc3, then yes, I agree this isn't a 2300+ puzzle.

This one is rated as 2400:

Perhaps it would be best to report your findings to the site, where the rating can be reset to something more reasonable.

It's 1934

This one is 2026 but likely too high still.

I took the screenshots with ratings from the info panel that is displayed after you finish a puzzle

Maybe one day I will find the right way to do so in the superb support bot, it does not like me

Note that these ratings are wrong when you solve rated puzzles. The actual rating of a puzzle can be seen if you visit it via its ID (available from your puzzle stats page).

Puzzles were just reworked, so probably just some minor bugs, where old numbers are shown. Though even 1900 is too high for those puzzles, there are still a lot of rating inconsistancys in the new system

it is because there is a better way to win material

It's possible if you're using regular rated puzzles, that screen is producing the old values still.

I checked and that screen is apparently still showing the old rating. I'm asking about it.

Indeed, also I can see the lower ratings in my puzzle history

Agree

Interesting. It seems like they still have a lot to fix.

Perhaps one-move puzzles need attention
