Another very positive comment here with a few grips. I love the way you used shadowing and color to create a board with a lot of depth. Interacting with the board is very very nice. My only major grip with it is the color scheme. As is often the case, you seem to want to add your own 'flavor' to the UI by having this almost post-apocalyptic color vibe... and as usually happens, it makes it more difficult to distingui…

Thanks for the valuable feedback!

I played a game, got my estimated rating (pretty accurate!), and a modal dialog box offering me the choice of "enter my email to create a account" or "forget me and play again". Immediately my heart sank. It's 2022, I have enough accounts on enough websites to last a lifetime and am super-sick of the whole "we've sent you an email, be sure to click the link to verify" dance. Most importantly, what I actually wanted t…

+ 1 to this, I dropped my email, but I really don't want to go and verify it. I'm curious to know what I get after I login, because it's not immediately clear. Another option is to consider 3rd party OAuth like Google.

Good suggestions, thanks.

I wish against 1.e4 it wouldn't always play 1...c5. Right now, it's less of a test of "what is your chess rating" and more of "how much sicilian theory do you know". Its prediction was about 300 points low compared to actual lichess rating (1800). But online chess is very different; you see a lot of unsound openings that an engine wouldn't ever play.

I think you were just unlucky with the opening! When I'm testing it's about 60/40 1...e5 vs 1...c5. The first opening moves should be quite close to what a 1600 FIDE player plays in online blitz.

Oh haha N=2 here, so you are probably right. Survivorship bias on my part.

I posted these stats in another thread:

According to https://lichess.org/analysis#1, for blitz and rapid games played on lichess with 1.e4, 1...e5 is 33%, 1...c5 is 25% and 1...e6 is 10%. And 35% is some other nonsense.

Does it use the frequencies from the lichess database? That would be pretty cool if it did!

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 the VOD of him playing noctie on his channel if you want to see the full thing.

fwiw I got kind of different results, first time around 1800 fide, second time around 1900 fide, third time, the only time I managed to win, around 1500 fide.

Yeah, I've noticed that resigning earlier in the game results in higher ratings for me. Perhaps it's because I stop playing as accurately once I have a crushing position?

Reaaaaaaally fun implementation! I enjoyed this much more than usual AIs I tend to play against as an extreme casual of the game. It put my lichess at 900, which is likely 100-200 points above what I'd really be. I'm gonna keep using this because it seems the difficulty is at the right spot for what I wanna do with chess.

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…

>P.S. I don't believe the comment above yours. The dude went from 2200 to 1300??

Like I could provide links to my games. I'm not a liar. I estimate I am a 1800-2000 player.

The thing I don't seem to know, it would seem to me when I play against a 1300 who never makes a blunder or mistake. It then happens 20 games straight. They certainly play various inaccuracies, and I hold myself as well as I do compared to stockfish 5.

In 1 game I was up 2 pieces and the computer didnt think they made a mistake nor blunder. >90% accuracy as a 1300...

I guess, I'm missing some fundamental thing.

I think these tools, much like IQ tests, are not that useful when you are super good and get almost every move perfect. It was fairly accurate for me who is around 1900 lichess.

Very cool!

FYI this sequence of moves leads to the AI timing out:

1. e4 c5 2. c3 d6 3. d4 cxd4 4. cxd4 Nf6 5. Nc3 g6 6. Bd3 Bg7 7. Nf3 O-O 8. O-O Nc6 9. d5 Ne5 10. Nxe5 dxe5 11. b4 a6 12. a4 Qb6 13. Rb1 Ng4 14. h3 Nf6 15. a5 Qc7 16. Bb2 Bd7 17. Na4 Bxa4 18. Qxa4
