irwin VS online-go.com

For Lichess, you can get some sort of idea from reading the code. If I remember correctly, there's some threshold for the site suspecting you of cheating based on a variety of simple metrics (accuracy, blurring, etc) and then it gets sent to machine learning tools to analyze (here is one of them, and here's another).

Lichess is open source. Here is their anti-cheating code on github: https://github.com/clarkerubber/irwin

Yeah Irwin is the old lichess model - here (https://github.com/clarkerubber/irwin) as well as the more maintained fork (https://github.com/lakinwecker/irwin/commits/master)

This is nonsense. They’re a free and open source nonprofit with no interest in commercial buyers. I’ve played on lichess for 3 years, over which time I’ve never encountered more than 1 cheater within 10 games (and normally much less than that). Because the website is open source, you can see the cheat detection they use. It’s not perfect — there is no perfect system — but it’s transparent and in my experience very good.

Isnt't lichess' cheat detection an ML based system?

What's this? It was given as an answer on a question about this on lichess https://github.com/clarkerubber/irwin

OGS is the closest thing I’ve found to lichess but it’s quite good! https://online-go.com/

That's nuts. I'll be honest online-go.com is my least favorite server to play on. Unfortunately it's one of the only ones that doesn't require software installation so it's easy to recommend to new players.

In 2016, I thought I'd give up on playing Go, seeing that our tree searching overlords beat us in every which way. Funny thing is, I'm playing a game right now [1].

Hey guys, I own Gomoku.com domain and the site (currently down) very similar to https://online-go.com/ I no longer have the time to maintain or try to grow it, if anyone is interested taking it over let me know!

and also, https://online-go.com (OGS) is the best English server for playing online and getting a rank.

https://online-go.com/ is the most popular English server, called OGS. It's pretty good.

OGS (https://online-go.com)

OGS is open source, anyone can contribute to their github repository and it's in need of developers - almost 200 open issues. It's likely easier to gain traction and more beneficial to the go community compared to starting from scratch.

OGS probably has the largest pool of English-speaking beginners. https://online-go.com/ It's a web app, so it's very easy to get signed up and playing.

Also, I'd suggest trying to switch to human players pretty soon (online-go.com is the place to be for that), AIs and weak AIs will play with a lot of strange and bad moves, and playing against too many of them might give you bad habits.
