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. Apart from 'regular' chess (also known as the Mad-Queen variant), it can play Capablanca chess, gothic chess, knightmate, cylinder chess, berolina chess, superchess and courier chess.

This is a very strong chess engine, placed second in the 13th world computer chess championship 2005. It uses the UCI (universal chess interface), for chess engines as communication protocol. This means to play against it, you will have to use an UCI capable interface, like knights. This distribution comes with an opening book of moves that the engine can use for the first few moves of the game. This increases performance in the chess games opening.

This is a very strong chess engine, finished 4th place at internatonal ChessWar X. It uses the UCI (universal chess interface), for chess engines as communication protocol. This means to play against it, you have to use an UCI capable interface, like knights. Or an xboard adapter like polyglot.

Gnuchess is an updated version of the GNU chess playing program. It is now based on the fruit chess engine and uses the UCI chess engine protocol. It has a simple alpha-numeric board display, and is also compatible with frontends like xboard, scid and eboard.

This is the opening book for gnuchess. It was formerly distributed together with gnuchess, now it has been separated due to size and architecture-independence. It is recommended that you install it if you want to use gnuchess.

Gnushogi is a computer player for Shogi (Japanese chess).

Gnushogi is a modified version of the gnuchess program. It can be used through xboard, tagua, xshogi, kaya, or other graphical frontends, but also has a simple alpha-numeric board display.

Most games (excluding Dai and Tenjiku) can be played through the XBoard GUI (version 4.8 and later).

chess engine compatible with xboard, but may also be used stand-alone, via terminal. Hoichess is written in C++ for GNU/Linux systems, but should work on most other Unix like systems. It provides also a xiangqi ("Chinese chess") playing program.

Pgn-extract is a program to extract selected games from a collection of chess games in PGN format. There are several ways to specify the criteria on which to extract: textual move sequences, the position reached after a sequence of moves, information in the tag fields, and material balance in the ending.

conversion tool to generate webpages from chess "portable game notation" PGN files. The webpages allow the replaying of chess games within a web browser.

It is also capable of playing on internet chess servers.

free chess engine derived from Glaurung 2.1. It is a chess engine, so it requires an UCI (universal chess interface) compatible GUI like XBoard (with PolyGlot), eboard, Jose, Arena or scid in order to be used comfortably.

Let your chess engines play tournaments against each other. This program manages setup and automatic running engine vs. engine matches, it has an interactive commandline and can start and stop the tournament, show current state and a crosstable. Every game will be displayed in a xboard session and can be observed. All games are stored in portable chess game notation, pgn.

This adapter allows a GUI using the Chess Engine Control Protocol (aka. CECP, or XBoard protocol) to communicate with computer players using USI (Universal Shogi Interface) or UCCI (Universal Chinese Chess Interface) protocols.

It also support the UCI (Universal Chess Interface) protocol, but for this one the "polyglot" package is a recommended alternative from the same author.

This metapackage includes a collection of games provided with the official release of KDE.

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
• Show best move sequence continuation, for these selected moves
• Displays a graph of winrate against move number

• Load and save games in SGF format
