# Ricefish
###### Stockfish's distant Chinese cousin
This is a "UCI" Chinese checkers engine. UCI is normally the _Universal Chess Interface_. This interface is implemented
exactly the same as for regular chess, with some notable exception(s):
- Moves are encoded as `AaBb`, with no spaces, indicating a move from row `A` column `a` to row `B` column `b`.
The current version is based heavily on
[bsamseth/goldfish](https://github.com/bsamseth/goldfish).
This is meant as a project to work on just for the fun of it.
Contributions are welcome if you feel like it.
## Build
The project is built using CMake, which hopefully makes this as portable as
possible. Recommend building in a separate directory:
``` bash
$ mkdir build && cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make
```
After the compiling is done you should have two executables in the build
directory: `ricefish` and `unit_tests.x`. The former is the interface to the
engine it self.
## Run
A _simple_ playing script is available to make this easier, see/run [play-match.py](play-match.py).
```text
usage: play-match.py [-h] --engine ENGINE (--human | --self-play)
optional arguments:
-h, --help show this help message and exit
--engine ENGINE Path to engine executable, i.e. `build/ricefish.x`
--human Specify to play as a human against the computer.
--self-play Specify to play the computer against it self.
```
You can play using the UCI interface directly, although this is a bit tedious.
Here's a short example of how to play with the engine (lines starting with `>` are the commands entered):
``` text
terminal $ build/ricefish.x
> uci
id name Ricefish v0.1
id author Bendik Samseth
uciok
> isready
readyok
> position startpos
> print
