I write all step for upgrading bot already. You can’t understand what?

That means the steps are over?

And can you screenshot the steps? Thanks.

And download playstrategy-bot-master

Also I want a bot specifically for standard chess variants.

Of course I know

Download Fairy-Stockfish to play chess and variants

1. Install Python

Go here: www.python.org/downloads/

Download and install it.

2. Install Notepad++

notepad-plus-plus.org/downloads/

3. Install 7-Zip

www.7-zip.org/

4. Download the bot files

Go here: github.com/Mind-Sports-Games/playstrategy-bot

Click Code → Download ZIP
Extract it using 7-Zip
Move the folder to your Desktop

5. Download Fairy Stockfish

fairy-stockfish.github.io/download/

Put it inside the engines folder
Rename it to stockfish.exe

Which version to use:

32-bit PC → use 32-bit Stockfish
64-bit PC:
bmi2 (best, for i3/i5/i7/i9 CPUs)
modern (ok)
x64 (weakest)

6. Create a bot account

Go to PlayStrategy
👉 playstrategy.org/signup

Make a NEW account (this is your BOT)
Do NOT play games on it
Verify your email

7. Get your API token

Go here: playstrategy.org/account/oauth/token

Name: Bot token
Tick all boxes
Copy the token

8. Edit config file
Open config.yml.default
Paste your token
Change this line:
url: playstrategy.org
Set anything else you want (time controls, variants, etc.)

9. (OPTIONAL) Make the bot weaker

Open your config and find the engine / UCI options section, then add or edit:

uci_options:
Skill Level: Your choice
Nodes: Your choice

What these do:

Skill Level (0–20): lower = weaker
Nodes: limits how much the engine thinks (lower = weaker/faster)

10. Save the file

Rename:

config.yml.default → config.yml

11. Open Command Prompt

12. Install required stuff

Run these one by one:

python --version
python -m pip install virtualenv
python -m pip install --upgrade pip

13. Set up the bot
virtualenv .\.venv -p python
.\.venv\Scripts\activate
pip install -r requirements.txt

14. Run the bot
python lichess-bot.py -u

15. When you want to run it again later.
cd C:\Users\YOURNAME\Desktop\YOURFOLDER\lichess-bot-master
.\.venv\Scripts\activate
python lichess-bot.py -u

I can't understand. Can you screenshot the steps so it might be easy to understand. And this is the first time I'm creating a bot account.

Very good guide
