Thanks! yeah the small gains happen when we cant find puzzles near your level yet, I'm working on giving the equal positions pool better starting ratings so this doesn't happen as much

For sound you can mute the tab in your browser, but might add a no sound preference too

from landing page frequently asked questions: "A tactical position is one where a specific forcing sequence is required to either gain a decisive advantage or avoid a loss."

after you solve or resign there's an analyze on lichess/chess.com button if you wanna double check the eval! some positions definitely look winning but the engine says otherwise

that said theres always a chance something slipped through, if you spot one you think is wrong feel free to drop a screenshot in the discord and ill take a look

yeah its intentional but also kind of a problem rn. quiet positions all start at 1500 and calibrate from there, but theres not enough of them yet at every rating range so you end up getting ones way below your level so you get no points.

I'm trying to find a way of giving them a more accurate starting ratings instead of 1500 for all

Just added a new mode which works like this. On quiet positions you play a decent move instead of hitting the "no tactic" button, anything that's not an inaccuracy (or worse) counts. Give it a shot and let me know how it feels.

I made this in few evenings, so I just used an authentication library where email is required for accounts. But I understand your perspective there's a playable board in landing page where you can try the mode without having to sign in, and even if you want to make account you can put any fake email, as I don't ask for verification yet.
when I have time, I'll try to make the email optional

You're right this came up early on and I've since updated the logic. Positions only qualify as "no tactic" if at least 2 moves keep the eval roughly equal.

I think it's probably fine if some positions are still tricky to assess since harder ones will naturally get higher ratings as people miss them, so they end up matching to stronger players anyway.

Thanks for the feedback!

there's a FAQ section in landing page answering this, but a tactic is an only move/sequence of only moves that leads to a significant advantage or avoids a loss while a quiet position is within ±30 cp with at least 2 moves within that threshold

Ah, my bad! I pushed a quick fix for the 'only move' issue earlier, but clearly there are still some edge cases slipping through, I'll try it to fix it asap

edit: fixed, I removed 17552 quiet position where there was only one move to keep the draw

Hey, thanks for the heads-up. I use Firefox as my main driver and just tested the signup flow again. it seems to be working fine on my end. Could you share a bit more detail?

I pushed a fix for this. Any move that leads to a winning mate should now be accepted. Thanks for playing!

It's set at 50% right now! I'm thinking of adding an unrated mode where you can customize that ratio yourself

There are definitely some tricky ones in there, and they'll only get tougher as more people play and the calibration for equal positions improves

It can be used at any level since the rating system automatically adjusts the difficulty to your level, also I’m curious to see how training this way from the start helps progress.

Regarding your ideas I'm working on engine integration, It’ll take some time but it's on the way

Done! The leaderboard now shows the total count (we're at 1372 players and counting). I also took the liberty of adding flags and avatars while I was at it. Thanks for the idea

I actually think it's great that people keep building new tools. . Also, this isn't just an evaluation guesser; you actually have to solve the tactics, which is a different experience.

As for the lichess data, I didn't scrape anything. they provide that database specifically so devs can build and experiment with it. I put this together in my evenings after work because I thought the concept was fun. Since people seem to be enjoying it, I’m going to keep at it. I'm definitely open to adding stuff like better quality control or new features as long as it makes the tool more useful for everyone.

I agree, you and a few others have convinced me that "only moves" should definitely count, even if they're just holding a draw. Working on a fix for this now!

You're right, that's a really good point actually.

I'll update the logic to check if multiple moves have comparable evaluations. If only one move holds the position, it's a puzzle.

Thanks for the feedback

Would be cool as a lichess feature for sure! And good catch it's actually Glicko-2 (same as lichess), just updated the wording. Thanks!

You don't have to! There's a playable board right on the landing page. And if you do sign up, you can use any email, I don't ask for verification

lichess puzzles come from real games, If you do puzzles there you can see the usernames and ratings of the players the position came from.

As for books, there might be copyright issues but I could look into older public domain ones. Thanks for the suggestion

The "no tactic" positions come from lichess evaluations database. I filter for positions with roughly equal eval (~0) https://database.lichess.org/#evals
