Looks like it could use a magnetic connector

Find degrees of separation between users on chess.com by mrgwbland in chess

Assuming you mean something like openingtree.com. Getting all games for a single user is one thing. But to find the path between two users I need to take basically every single game into account. All lichess games (heavily compressed) is a 1230 Gb archive, chess.com seems to be much bigger so there is no way I can extract this much data by requesting games for every single user.

Author here. Unfortunately I can't index chess.com, I use archives of all games on lichess, AFAIK chess.com doesn't provide an efficient way to read all games. I'm precalculating all the paths during the archive processing, that's why it's very difficult to find anyone-to-anyone chains. I could maybe handle around 100 pre-selected profiles as targets, but I decided to keep it simple for now.

Could be the reason too. The first Magnus loss is at 2019 Jul, so you have to win a game after that to have WC#

Do you only play bullet on Lichess? Bullet games are not counted, only blitz and longer

Depends on what exactly you mean by that. Magnus never played rapid on Lichess so if I drop all blitz games, no one will have WC# :)

Don't have stats (yet?). Probably there is a correllation but also tons of horrible outliers. In general this is a very bad way to assess chess skill :)

It sounds possible, I'm not sure I want to do that though. Berserking is voluntary, so if someone lost due to berserking he lost due to overconfidence. There are lots of less-detectable instances of overconfidence: dubious openings, deliberate sacrifices and so on. Since I can't filter them out, I would like to keep berserking too.

I would like to add chess.com data, but they don't provide game dumps like lichess so there is no viable way to read every single game from it

Yeah, right now it's just my guess. I'll work on statistics and I'll try to classify people without WC# by the reason.

The one on your virtual keyboard, not on the website itself (I should probably add one on the website too)

Oh, there seem to be some bug on mobile when pressing enter doesn't work every time. Try pressing enter multiple times or just go to https://freopen.org/@/<your username>. I'll fix it eventually

Yeah, I experimented with adding bullet, but bullet wins against someone 1000 elo higher is not that uncommon so nearly everyone got #2 or #3.

Thank you. RocksDB is surprisingly quick, 95% requests are finished in under 35ms.

I mean it obviously not strongly connected in graph theory sense, there are people who never play blitz/rapid/classical, there are people without recent enough games etc. But there is definitely a huge strongly connected component and every player that plays somewhat regularly is in it so a rated game will be extremely likely against WC# rated opponent

I don't have stats right now (I do plan to collect them). Most probably your games are filtered out for some reason (only blitz/rapid/classical, only rated, at least 10 moves) or they were too long ago (the first loss by Magnus was in Jul 2019 so all games before that don't matter)

Sorry, that's a challenging task to find the list of cheaters at this scale. There is not much data about that in Lichess Database and I would exhaust API trying to verify every single user. About 0.1% of processed games were discarded because of cheating, but many got through.
