pgn-tactics-generator VS irwin

- A more advance https://github.com/vitogit/pgn-tactics-generator

Why is server side necessary ? For eg : If you run a tactics generator yourself like this one : https://github.com/vitogit/pgn-tactics-generator, it takes about 6- 8 minutes to analyze a single game at depth 8.

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
