Applechess
Applechess is a simple chess engine, written using the minimax and alpha-beta pruning algorithms along with a handcrafted heuristics function.
See more information about the two algorithms on the Wikipedia pages: minimax and alpha-beta pruning.
The easiest way to play the engine is to play the bot on Lichess by sending it a challenge request (variants and ultrabullet are not yet supported).
The engine may run slow if too many people are playing it. If the bot is offline, you can run it locally.
Running Applechess Locally
In order to run the engine locally, first install Python from python.org or your package manager.
Python 3.10+ is required.
Then, clone and install the requirements. You can optionally create a virtual environment before installing the packages.
git clone https://github.com/appleplectic/applechess.git
cd applechess
python -m pip install -r requirements.txt

To use the ChessAgent class:
from applechess.chess_agent import ChessAgent

agent = ChessAgent()
agent.interactive_terminal()

Check the documentation for usage details. Note that the API is not stable, and will change frequently.
Running the Lichess bot locally
Follow the same instructions above to clone and install dependencies.
Next, create a Lichess bot account by first registering on lichess.org and then obtaining a personal access token under settings.
Upgrade the account to a bot account by running the following command (an account with any games on it cannot become a bot account):
curl -d '' https://lichess.org/api/bot/account/upgrade -H "Authorization: Bearer <yourTokenHere>"

Finally, create a .env file in either the root directory or the applechess/ directory with the following contents:
LICHESS_API_KEY=<yourTokenHere>

The bot should be ready to run:
cd applechess
python lichess_bot.py

Building the Documentation
First, follow the previous instructions to download the dependencies.
Then, build the docs:
sphinx-build -M html docs/source/ docs/build/

The built docs should then be available in docs/build/html/.
