Ethereal is an UCI-compliant chess engine. It uses the traditional alpha-beta framework in addition to a variety of pruning, reduction, extension, and other improvements. It's greatly influenced from Crafty, Stockfish, TSCP, MadChess and Fruit.

Fairy-Stockfish is a chess variant engine derived from Stockfish designed for the support of fairy chess variants and easy extensibility with more games. It can play various regional, historical, and modern chess variants as well as games with user-defined rules. For compatibility with graphical user interfaces it supports the UCI, UCCI, USI, and CECP/XBoard protocols.

The goal of the project is to create an engine supporting a large variety of chess-like games, equipped with the powerful search of Stockfish. Despite its generality the playing strength is on a very high level in almost all supported variants. Due to its multi-protocol support Fairy-Stockfish works with almost any chess variant GUI.

Variants larger than 8x8 are only supported on 64-bit platforms.

Fairymax is a program that plays chess and chess variants. It uses the xboard/winboard chess-engine protocol to communicate.

A Go program with no human provided knowledge. Using MCTS (but without Monte Carlo playouts) and a deep residual convolutional neural network stack.

This is a fairly faithful reimplementation of the system described in the Alpha Go Zero paper "Mastering the Game of Go without Human Knowledge". For all intents and purposes, it is an open source AlphaGo Zero.

https://deepmind.com/documents/119/agz_unformatted_nature.pdf

No network weights are in this repository. If you manage to obtain the AlphaGo Zero weights, this program will be about as strong, provided you also obtain a few Tensor Processing Units. Lacking those TPUs, the author recommends a top of the line GPU - it's not exactly the same, but the result would still be an engine that is far stronger than the top humans.

Recomputing the AlphaGo Zero weights will take about 1700 years on commodity hardware. Upstream is running a public, distributed effort to repeat this work. Working together, and especially when starting on a smaller scale, it will take less than 1700 years to get a good network (which you can feed into this program, suddenly making it strong). To help with this effort, run the leelaz-autogtp binary provided in this package. The best-known network weights file is at http://zero.sjeng.org/best-network

Features include:

• Show win rates and confidence levels for selected moves on the board
