IZII is a Python Chess Engine
Decisions are made using the minimax search algorithm with alpha-beta pruning to optimize search time. The engine is compatible with xboard or any other GUI using xboard/winboard protocol.
IZII makes decisions in two key steps.
- Move Generation
- Search IZII works by first generating a moveset of all possible pseudo legal moves. This would include moves which would put the king in check. Then IZII prunes this moveset by checking for all cases and produces a set of legal moves. A minimax search is performed on the given board state generating a game tree at which all possible moves are explored to a modular set depth. Enjoy!
IZII is packed with a script to run IZII on xboard
- Be sure you have xboard installed
brew install xboard - Clone the repository
git clone https://github.com/ElliotVilhelm/IZII.git - Navigate to the directory
cd IZII - Execute the script
./scripts/run.sh
You can press ctrl-t on your keyboard and IZII will begin to play itself
pip3 install pytest

I wrote IZII on my free time as a means to improve my python and because I love chess! To implement IZII I used a 120 square chess board as used by Cray-1, one of the first chess playing computers.
IZII provides two key functions for playing chess:
get_all_moves_at_state(state)
outputs: all possible moves
run_move_at_state(state, move)
outputs: next state
