Overview
Pikafish is a free and strong UCI xiangqi engine derived from Stockfish that analyzes xiangqi positions and computes the optimal moves.
Pikafish does not include a graphical user interface (GUI) that is required to display a chessboard and to make it easy to input moves. These GUIs are developed independently from Pikafish and are available online. Read the documentation for your GUI of choice for information about how to use Pikafish with it.
See also the Pikafish documentation for further usage help.

This distribution of Pikafish consists of the following files:
-
README.md, the file you are currently reading.
-
Copying.txt, a text file containing the GNU General Public License version 3.
-
AUTHORS, a text file with the list of authors for the official Pikafish project.
-
src, a subdirectory containing the full source code, including a Makefile that can be used to compile Pikafish on Unix-like systems.
-
a file with the .nnue extension, storing the neural network for the NNUE evaluation.

Donating hardware
Improving Pikafish requires a massive amount of testing. You can donate your hardware resources by installing the Fishtest Worker and viewing the current tests on Fishtest.
Improving the code
In the chessprogramming wiki, many techniques used in Pikafish are explained with a lot of background information. The section on Stockfish describes many features and techniques used by Stockfish. However, it is generic rather than focused on Stockfish's precise implementation.
The engine testing is done on Fishtest. If you want to help improve Pikafish, please read this guideline first, where the basics of Pikafish development are explained.
Discussions about Pikafish take place these days mainly in the Pikafish Discord server. This is also the best place to ask questions about the codebase and how to improve it.
Compiling Pikafish
Pikafish has support for 32 or 64-bit CPUs, certain hardware instructions, big-endian machines such as Power PC, and other platforms.
On Unix-like systems, it should be easy to compile Pikafish directly from the
source code with the included Makefile in the folder src
. In general, it is
recommended to run make help
to see a list of make targets with corresponding
descriptions.
cd src
make -j profile-build
Detailed compilation instructions for all platforms can be found in our documentation. Our wiki also has information about the UCI commands supported by Pikafish.
Terms of use
GNU General Public License version 3
Pikafish is free and distributed under the GNU General Public License version 3 (GPL v3). Essentially, this means you are free to do almost exactly what you want with the program, including distributing it among your friends, making it available for download from your website, selling it (either by itself or as part of some bigger software package), or using it as the starting point for a software project of your own.
The only real limitation is that whenever you distribute Pikafish in some way, you MUST always include the license and the full source code (or a pointer to where the source code can be found) to generate the exact binary you are distributing. If you make any changes to the source code, these changes must also be made available under GPL v3.
