A chess bot that’s really good at getting a draw
OKAY so i kinda forgot to make updates…
but here’s what ive done so far:
- ran hours of simulations to test draw rates of other existing bots
- made the framework so i can start training
next: - train the neural network!
LOTS of hours put in. in summary:
- made uci, which allows me to spin up instances of existing chess engines for verification & simulation
- made fastboard, a fork of pychess’s board class, which is much faster at checking for draws
- made a baseline “dumb” bot that looks at legal moves and sees which one would increase stockfish’s evaluation of a draw the most, then makes that move.
- made a game class that allows bots to play against each other. it takes ~70s for a game between the baseline “dumb” bot & stockfish
- made a pgn class that allows me to save what happened in a game and the result, which will help for data analysis down the line
image is of a real chess match that my bots played, saved and then opened in lichess. you can see in the bottom right that it ended in a draw, which is a good thing
