# Laveno

This is Laveno One, a pure Elixir chess engine.
It includes board representation, game state management and valid moves generation as well as a set of board state evaluators with finders.
A finder is a game play brain to actually play a game.
It has UCI support, which enables using a chess GUI to interact with the engine.

Laveno exposes a handy API for each of it's components.

## How to play

```sh
mix escript.build
./laveno
```
So it is ready to recieve UCI commands

```sh
printf 'uci
isready
position startpos moves e2e4
go wtime 1000 btime 1000 winc 0 binc 0
quit
' | ./laveno --finder alphabeta-negamax-ets | cat
```
