Les meilleurs entrainement d ́echecs quotidien, sont les puzzles/problemes..
why can't see my rating
@BasemBasem we can't allow you to see your rating because that could be used by some people to compromise the integrity of the competition
Thank you for your understanding
is this just about predicting the puzzle "rating"?
As a chess person, I find this problem very well addressed by all the tactics trainers around: lichess, chess.com, chesstempo. I very seldom find myself given with a problem and then, after solving it, thinking that the difficulty rating was crazy far from my perception. Of course this may change for player stronger than me, but this is how it feels to me weak player (and problems solver).
The simple logic followed today, considering each puzzle as a game and adjusting opponents ratings accordingly, seems to be an "unbiased estimator" of the actual diffculty level. Online trainers propose the puzzle to a very high volume of players, so even if the convergence of the estimator was a bit slow, the vast majority of puzzles in the set ends being positioned in very reasonable ranges.
An area that I would find more interesting (very very humble two cents) is how a puzzle feels. Sometimes I play something and I have a clear feeling of something that was picked by an engine, becasue an eval function has a sudden variation but the position feels artifical and "not teaching me much". some other times I have a feeling that a position was carefully selected to represent a principle, and it's like point to a weakness of my chess brain. A lot of the positions in the online trainers fall in the first category, while a good "tactics" book tends to provide of lot of the second.
Inferring this perception on large dataset of puzzles, guessing wheter a human will perceive it as dry and mechanical or rich and satisfying, this is something I'd be very happy to help with, both as a player and as a data person.
Great idea but tbf I don't think relying on people creating an account with the same username as on lichess is great:
1. Because I couldn't be bothered to create yet another account on a website
2. Because I could create an account with someone else's lichess username and you have no way to verify it.
Couldn't you implement a login via lichess, using its API? Don't quote me on this but I think this should be helpful?

Disclaimer: not a dev myself.
I would have preferred if you had disclosed who precisely "we" is. Based on the first paragraph, I thought you were lichess developers and I have the impression, that this misdirection is intentional.
