FabChess

UCI compliant chess engine in Rust.

This is only an engine, connect it with a gui for real usage.

Wiki

Interested in how it works?

Check out the wiki at: https://github.com/fabianvdW/FabChess/wiki

Setup

Download latest release for your OS in the release section.

Compilation Guide

If you want to compile from source, make sure you have the latest version of Rust and Cargo installed. The only valid way to compile the engine due to Rust's feature system having issues with workspaces is:

git clone https://github.com/fabianvdW/FabChess.git
cd FabChess
set RUSTFLAGS="-C target-cpu=native"
cargo run --release -p uci-engine
...
< info string Initialization Time: 0ms
> uci
< id name FabChess v1.15 BMI2
< id author Fabian von der Warth
< id contributors Erik Imgrund, Marcin Mielniczuk, Terje Kirstihagen
< option name Hash type spin default 256 min 0 max 131072
...
< uciok
go infinite
...

The binary is in ./target/release/uci-engine(.exe)

Usage

FabChess supports more commands than the standard UCI specifies.

Static evaluation

Use static to get a static evaluation of the position

> position startpos
> static
< cp 10

Display evaluation

If you compile FabChess with an extra flag, it will also write a detailed overview of the evaluation to a logfile. For this, you will have to change core-sdk/Cargo.toml to include the feature in the default features: default = ["display-eval"]

!!! Make sure not to run any go command with this, else it will quite literally produce a lot of text !!!

> cargo run -p uci-engine
> position startpos
> static
< cp 10

Perft

You can run perft on an arbitrary position. Note that if there is no king on the board for either side or the position is otherwise illegal, FabChess will crash (intended).
