Very cool but noctie seems to be timing out now - worked fine for me the first two times.

Does noctie treat the opening any differently when factoring in ratings. I had two very different estimes - higher one (2100) was from an opening line i knew and lower one (1500) I left the opening more quickly but I don't think I played a much worse middle game. I'm closer to 1500. [edit: from your other comment it does look like it takes the opening into account - I'm guessing as some sort of calibration - if you create an account does it use the results from previous games instead?]

Also curios if this could theoretically be applied to historical games as well or does it require noctie to be a participant. I'd love to see an analysis of how player strength has increased over time. [edit: from your other comment it looks like it does require play]

I played a few moves and it seems the AI just stopped playing? This happened twice now (at move 3 the second time). I'm not sure it should take that long especially in opening moves. Is it doing very deep analysis? Am I up against depth 40 stockfish calculations here?

Hey, sorry to hear that, the moves should usually be played very fast in the opening, and only up to 5–10 seconds in tactical situations, so I think you might have encountered a bug. Noctie does almost no calculation, just like a human, BTW. Was this in the rate-me page or as a logged in user? You can mail me with the e-mail in my profile if you'd like to help debug!

Had the same problem as well. Actually, I wasn't able to finish a single game since it always got stuck (took more than a minute to play a move) after a while.

I'm using Chrome on Android and was only using the rate me page.

Earlier quoted context omitted.

On lichess? I been hovering in at 1300+-50 for the last year... I can barely beat stockfish 2. I've found stockfish at these lower levels doesn't play like humans at all. It will play a near perfect game for 25 moves and then all of a sudden make a horrible and senseless move. If your style is slow and defensive I think you probably fair better. My style is hyper aggressive and stockfish crushes me :)

Just want to point out the obvious: if you are staying at 1300 for over 1y, you are not improving and likely not understanding why you are losing. I would recommend you study rather than banging your head against the wall by playing more games. Opening theory and tactics are a good place to start. An easy step is make sure you know a few common openings and have at least one response prepared to each. But also a good…

I think your just trying to be helpful, but ya it did come off as pretty patronizing. You've also assumed incorrectly that "getting better" is the most important thing when playing chess...

I play chess because I find it fun, relaxing and a great way to blow off stress. Studying opening and caring too much about rating ruins that. Rated play is awesome because I always get paired with someone of similar skill. I do feel I'm improving slowly, even if my rating does change much. I like to mix things up and often play strategies I know are bad because it leads to fun and novel positions.

And yes, I understand that I'm not a "strong" player. It's pretty obvious when lichess tells me directly I'm in the bottom ~30% lol.

This is fun. No idea what my actual rating is but I may have found a bug: I won with checkmate playing white and a rating of 828 as anon. 1. d4 d5 2. Nf3 Nf6 3. e3 e6 4. Be2 c5 5. Bd2 cxd4 6. Nxd4 Nc6 7. Nf3 e5 8. Bb5 e4 9. Ne5 Bd7 10. Nxc6 bxc6 11. Be2 Rb8 12. Nc3 Rxb2 13. Na4 Rb8 14. Nc5 Qb6 15. Nxd7 Nxd7 16. O-O Nc5 17. Bc3 Na4 18. Be5 Rb7 19. Rb1 Nb2 20. Rxb2 Qxb2 21. Bxb2 Rxb2 22. a4 Bc5 23. Bg4 d4 24. exd4 Bxd4 25. Qxd4 Rxc2 26. Qd7+ Kf8 27. Qd8#

Played a few games and variation was between 828 and 1251, and in all but the 828 I received a good drubbing.

Thanks! Yes, the traffic from here exposed a few issues & bottlenecks in the backend infrastructure. I have resolved most of them and it seems to be running OK now (?).

To answer your questions: Noctie takes every move into account. Especially in short games or very one-sided games, a lot of the rating estimate will come from your opening play. If you play a bad opening, Noctie adapts and you will get an easier game, which may lead to simpler positions where you have less risk of making a mistake that would lower your rating. So what opening you play definitely has a big impact when trying to judge the rating from one game only.

If you create an account and log in, Noctie will accumulate information from several games to give a more balanced difficulty and more accurate rating estimate (and show how it changes over time).

Noctie's involvement isn't strictly required for the rating estimate although it creates good conditions for it by making the game balanced, not dominated by time trouble or trying to flag the opponent, etc.

I asked GM Minh Le (twitch.tv/gmminhle) to try it out, and he got a 2046 FIDE rating with 2306 lichess rating, after beating the bot. His actual FIDE rating is 2542 standard ( https://ratings.fide.com/profile/12401153 ). His feedback was: -Why does the bot get +20 seconds every move and you get +5 seconds? -It seems like you have to wait a few seconds before making a move before the bot gets stuck You can check out t…

Hey, that's really cool, will check it out! The backend was experiencing some issues leading to laggy play by Noctie, I hope it's working better now.

https://noctie.ai/walkthrough/public_55e0d2f7-d18e-42aa-a969...

both the machine and i played with elan (reckless abandon), rarely thinking more than a few seconds per move

crazy game that convinced me to sign up

i love that it ostensibly tried to stalemate me at the end, that's what i'd do too and often draw back when i played chess

i stopped because F** zero-sum games

but against noctie i'm not releasing stress hormones into someone's brain so i can like chess again

chess.com analysis

accuracy 75.4 vs 70.6 so it did a measurably good job matching performance

there is something very lifelike and appealing about an AI that blunders at the same rate as you

best chess engine, good job
