How to make a Lichess bot in Python
Clone https://github.com/lichess-bot-devs/lichess-bot.git into your new project! Make sure you have github installed!

Interested in creating, playing and testing your own chess engine?
https://github.com/ShailChoksi/lichess-bot is a straight forward way to use any UCI engine with lichess. There are also a few libraries for move generation mine: https://github.com/Disservin/chess-library , libchess: https://github.com/kz04px/libchess , surge: https://github.com/nkarve/surge . These are C++ ones, for rust theres https://github.com/analog-hors/cozy-chess . In python you could use python-chess but its incredibly slow for engine stuff writing your own will probably be faster if you know what you are doing.

I have created a chess engine in python. How do I modify it for UCI protocol?
I would recommend downloading this bot, written in Python: https://github.com/ShailChoksi/lichess-bot
Once you have these basic UCI commands implemented, you can use this application to run your engine as BOT on lichess.

I made a 1660 lichess bot
The bot uses the Shail Choksi's lichess-bot package (link) and stockfish. It's currently running on pythoneverywhere.com. I am very much a hobbyist and this is the first time I've done anything "useful" with coding. If you encounter any bugs, DM me and I'll do my best to fix them.

Is there a chess platform that explicitly allows computer play?
You can make a lichess bot with your engine (https://github.com/ShailChoksi/lichess-bot or similar API). The instructions are all fairly straightforward, but if you need any help feel free to reach out!
-
How do people go about testing chess engines against each other?
If you just want to make your engine play some games, with a uci interface you can quickly setup a bot account on lichess and challenge any available bot. https://github.com/ShailChoksi/lichess-bot

The CrowdStrike file that broke everything was full of null characters
I play one of those games that doesn’t strongly enforce anti-cheating, and I agree with you that it’s a huge detraction compared to games with strong anti-cheat.
But I strongly disagree about the use of invasive client-side anti-cheat. Server-side anti-cheat can reduce the number of cheaters to an acceptably low level.
See for example how lichess detects and aids in detection of cheaters: https://github.com/clarkerubber/irwin
And chess is a game where I feel like it would be relatively hard to detect cheating. An algorithm looking at games with actors moving in 3D space and responding to relative positions and actions of multiple other actors should have a great many more ways to detect cheating over the course of many games.

How common is false banning in chess?
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 - Cheaters, bots, AI-based human hybrid opponents
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.
- A question for technologists: can we start an open-source cheat-detection engine that becomes the gold standard of cheat detection engines?
- Can we see the Lichess cheat detection stuff?
- Banned for cheating, appealed, denied. What now?
