Computer-Chess Wiki

This is a list of Chess GUIs that support at least one major chess communication protocol (Winboard, UCI or Chessbase). The former very common Millenium Chess System (MCS) is only used by a few graphical user interfaces because Millenium 2000 GmbH - Hegener & Weiner, a private limited company in Germany, sells nowadays chess computers, game consoles - but no pc software (information by Djordje Bucan, department service). Free available frontends are available on GitHub and SourceForge

• AlienBoard - GUI for Android systems which can be used for many variants or other board games (Checkers, Go, Reversi etc.) respectively online play on chess servers; for further details see Daniel Shawul´s page Scorpio Chess and Nebiyu Alien

• AllPawnsMustDie - Chess Engine GUI for UCI using C# and WinForms by Matthew Baker - author´s statement.”This is not a completed GUI, it is still very much a work in progress and just a pet project. There is no way currently for a user to play the engine via the GUI. That is something I am working on. I can add screenshots later if it's still needed, but this should be all you need to do step wise to run it: a) Install VS 2017 Community edition (free one) b) Clone this repository e.g. into c:\apmd c) Open the solution at c:\apmd\AllPawnsMustDie\AllPawnsMustDie.sln d) Press F5 to run it. e) In the current state you must first load an engine. Do this with “File→Load Engine” f) If you select “File→New Game” not much will happen at this point, I think the board will just draw. g) If you select “File→Self Play” the engine will play itself in a loop to exercise the portions I have hooked up so far. h) The only UCI engine I have used so far for testing is Stockfish 8.” - MediaFire

• Analyze Chess - This (Free) and Analyze Chess - This (Pro) by Asim Pereira; features: Load and analyze your games from PGN file, Save moves and variations, Paste PGN or FEN, Share PGN/FEN with other Chess apps like Droidfish or send via Email/Twitter, Manage and install new UCI engines, One click analysis from iChess & Chess Book Study apps, New innovative feature to move back and forth by simply tilting your device.

• Chess Buddy - Download - default UCI; commercial product (trial version for 7 days) for Yahoo Chess and Pogo Chess including Tao engine by Play Buddy LLC; for further informations about membership / prices etc. see the menu Frequently Asked Question Topics or click there on “Buddy Instructions” - support-team´s review: “The trial and purchased version of Chess Buddy are exactly the same and can be used just as it is only. Chess Buddy can play against any opponent on Club Pogo be it human or player, although the win rate may change depending on the difficulty of the opponent. It is supposed to allow you to insert your own engine but that feature has been buggy for some time so only Tao is functional. This Buddy is one we have on our 'to redo' list at which time it will be completely updated and modernized (watch our 'Updated Buddies' page for news of that). Once the subscription expires it will open to the 'Trial Expired' window so accessing the GUI is not possible at that point.”

No way to use simultaneously several UCI engines in Chess King. But changing engine is operation for very advanced users. One need to edit some files (in interface no dialogue for adding other UCI engine) and we indeed don't describe this ability in help and manual. The same and with using WinBoard engines in Chess King (Convekta support).

• ChessPro - a GUI with UCI-support by NeuroXiq

• Chess Rocks - UCI-compatible graphical interface by Kenneth Chamberlain for playing or analyzing; WinBoard/CECP-protocol is not used. The description by its author has the following content: “There are 4 main modes, game play, position setup, move analysis and game analysis. You will need to have at least one UCI engine on you system for engine play or analysis. Two engines may be selected to play against each other. Of the engines I have tried Houdini, Critter, Stockfish and Streika seem to work well, Rybka and Aretar do not. I am interested in feedback on the program, especially about how the movelist RAV's were implemented. I have tried to make this a very simple to use application, other than the selections that are on the main window all other input is done through context menus. For example the Load and Save buttons have context messages for different possible sources and destinations. All options that a particular engine supports are displayed on it's respective tab page once it has been started.” - The author´s statement after extraction and selecting the chessboard symbol chessboard is: “Press the retry button and it will let you browse for the folder where the pieces are. Same would go for the engine and sound resources. There is are subfolders in the resource folders for each of those, of course I provided no engines.”

• ChesSMS - an application that lets you play Chess over SMS, powered by Twilio. ChesSMS should in theory work with any UCI compatible chess engine. It is known to work with Stockfish. If using stockfish, compile it according to your machine and copy the binary to priv/bin/stockfish. If using another Chess Engine, you can put the binary where ever you want but you'll have to modify src/chessms_server.app.src and change the engine_path configuration parameter. To connect ChesSMS to an SMS enabled Twilio number, sign up for Twilio and buy a number (if you haven't already). Configure the SMS URL of the phone number to point where your ChesSMS server is running.

• ChessSpeak - a voice interface created by Fred Mellender; it allows you to speak moves to any UCI chess engine and receive the engine's move in audio. This lets you set up a real board and pieces across the room from the computer and play a game against the engine without having to use the mouse, keyboard, or monitor. Some find this a more natural way to play chess and their “board vision” benefits from using actual pieces. You can use the program to practice blindfold chess; it has a graphical interface too. Additionally, ChessSpeak will calculate your rating and ratings for chess engines - User´s Guide

• Chesster - alfa state project by Basti Tee; Python-frontend for any UCI-compatible chess engine with Stockfish being included and PGN (command-line tool to analyse respectively annotate chess games); console client to play against Stockfish; standalone-server to send UCI commands over the web to a chesster instance

• Chess Tournament - with this Javiolo app for Android you can only play chess tournaments between engines/modules; Gurcan Uckardes says: Indeed, CfA is simple, stable, handles XB engines and has low memory usage but that doesn't mean it's complete. The app can use UCI engines as well as tablebases. But for the moment, full reliability isn't yet achieved. So, Chess Tournament, available for free download from GOOGLE PLAY has the opportunity to become the king vey soon.

• ChessUI - Chess Symphony by Martin Konečnik; ChessUI or Chess Symphony is a GUI for playing chess either between two human players or against an AI. It does not come with a chess engine. It is, however compatible with any UCI based engine (for example Stockfish). The application is written in English and localised for Slovene. Basic functionalities include highlighting possible squares, notifying when the king is under attack. It also supports all special moves in chess (En passant, Castling, etc.). Playing board is fully customizable as textures for squares and units are loaded at runtime. Pieces are named in the following manner: first letter represents color (b or w), followed by the first (pronounced) letter of the figure (b-bishop, k-king, n-knight, p-pawn, q-queen, r-rook). Squares are similarly named bsq and wsq. To load a Chess Engine go to Options → Settings and locate the endine's executable. You can also set AI difficulty by setting search depth from 1 to 20. Higher depth can mean much slower AI turns. In the second tab of Settings you can also change square color/texture, change font of chessboard markings or load a different set of pieces. All settings are persistent. In the right window moves are registered and on the bottom you can see detailed decision logic made by AI when playing against it.

• ChessV - a free, open-source universal chess program with a graphical user interface, sophisticated AI engine, and other features of traditional Chess programs. As a “universal” chess program, it not only plays orthodox Chess, it is also capable of playing games reasonbly similar to Chess.

• DETROID - A chess engine framework by Viktor Csomor that handles the UCI protocol, provides a chess GUI, and serves as an engine parameter optimization framework. An engine only needs to implement the interface TunableEngine to be usable as a UCI chess engine, the search engine of the GUI, and to be tunable. As the framework includes the Detroid chess engine , which is by default used as the controller engine for the GUI and for tuning, other engines using the framework do not have to implement the ControllerEngine interface. The ApplicationFramework itself is a Runnable class whith a single two-parameter constructor. The first parameter is an EngineFactory instance which is responsible for creating instances of a TunableEngine and a ControllerEngine. This is where Detroid is used as the ControllerEngine by default to avoid having to implement the interface to tune the engine, use it in the GUI, or use it as a UCI engine. The second parameter is an array of strings for program arguments which define the behaviour of the framework. To launch the framework, an instance of ApplicationFramework needs to be constructed and run in the main method of the application. The following sections describe the features of the framework and present the usage of the program arguments. The complete Javadoc of the framework can be found here: current version

• DoubleChessBoard - an application (including Defeo / Sjeng / Sunsetter) by Dušan Škaloud that plays bughouse, but has no button / menu for standard chess; in analyzing mode it is possible to type “variant” (bughouse, standard are supported and maybe even coin). The programmer´s resume was: In version 1.55 theoretically you can run any WinBoard engine, but I am not sure with standard chess variant outside analyze window (Net / StartNewGame / Setup board and then analyze by engine) works, because of this shortened engine running and output processing functionality which I made fast for bughouse Sjeng; for Sunsetter type “engine especially (playing)” and Sjeng type “engine analyzing” - bughouse chess engines

• Eschecs - Eschecs is a free chess playing program for the Windows system by Roland Chastain; UCI-support with the open-source engine Moustique written in Pascal

• Ethereal Chess - 3D chess program by Jordan Sparks capable of communicating with any UCI compatible AI engine; does not have its own engine; free edition of Houdini is used; works with Critter too - but with Stockfish occur problems at the moment; has no relationship with Andy Grant´s Ethereal chess engine - he said: “My engine is UCI compatible, and contains no graphical interface of it's own. As of now the project is not fully UCI compatible, and only has enough code to do the testing I am currently doing. I am aware of EtherealChess which is just a GUI with an engine hooked into it. My project is a completely separate project.” - CCC Thread

• Haundrix Chess - a WinBoard-compatible open source project by Alex Ignácio da Silva that comes with the engines Crafty / GNU Chess / Sjeng; author´s answer in the help forum: There is a way, but only if the engine speaks the Winboard protocol (UCI is not supported). The procedure is not user-friendly, but isn't complex either: it involves creating a Haundrix plug-in, which is basically editing a simple XML file. If you're ready to the challenge let me know, and I'll be glad to provide you with instructions on how to accomplish it

• Hawk Chess - a commercial product/ user interface (full version) for Android by Digitalhawk, but the free edition is ad-supported; contains the following features: play against a variety of compatible UCI chess engines, including the built-in Hawk engine - variable skill levels for supported engines - switch engines and adjust their skill in-game - variable time controls - undo moves - create human-only games, with a chess engine on-hand to provide hints - respectively engine-only games, useful for learning and your general interest - play multiple off-line games concurrently - ask for hints from any installed engine - Hawk Chess Server & FICS - PGN support - review and play back completed games move-by-move - set up positions by board editor - 2D/3D graphical layout for different screen sizes etc.

You need to install both Ruby and (at least) QtRuby to run Kaya. You don't actually need the KDE binding (which is probably a pain to install on Windows). It used to work fine with older versions of QtRuby, but you'd probably need to make some minor modifications to be able to run it with current versions. Ruby v1.9, Qt or KDE bindings certainly < v5.0”

• Little Blitzer - a free Windows tournament manager program by Nathan Tom for UCI based chess engines. It was created to enable playing thousands of very fast games using multiple threads for chess engine testing purposes. It creates a PGN file designed to be used by Bayeselo or Elostat to give a final rating for each chess engine. It is useful for both chess programmers and chess testers as you can run tens of thousands of games at fast time controls in a fraction of the time you could with a traditional GUI interface. Some of the major features: Can allocate per-engine time with sub-millisecond accuracy. Very low tournament overheads so you can allocate every available CPU to the chess engines. Utilises LittleThought's efficient move generation code to maximise performance. Can run multiple engine vs engine games in parallel - for example, on a 4-core machine you can run 4 single-cpu matches, or on a 8-core machine you can run 4 dual-cpu matches. Displays real time statistics on each engine's performance, and distinguishes between different types of game results such as loss by timeout or loss by illegal move. Outputs PGN file for direct import into Bayeselo. Supports Gauntlet or Round-Robin tournaments, respectively Standard or Chess960 variants. All engines can be configured separately. Can set tournament level settings such as hash table size and time controls. Can adjudicate games early based on specified criteria, to further speed up the tournament. Supports starting positions loaded from FEN, EPD or PGN files.

• MinkiChess - chess coaching and playing program by Balachandran Subramaniam; he wrote the following message: “Minkichess currently uses the stockfish engine. However, the engine is used to analyse on behalf of the ai object. The ai part then selects the moves on its own criteria. Example: 1.e4 d5. Here the engine is asked to give evaluation for all possible replies, for, say depth 4. Then the ai decides with some probablity what to do. It can choose a random move (low levels) - moves within a margin of 50centi-pawns - a capturing move - decide to go for a deeper analysis and use the returned result. The trick is to make the ai make errors similar to humans. So basically any engine will do as long as the performance is calibrated. The calibration is done against Chessmaster 8000 personalities and Houdini_2.0 reduced strength settings. As for other engines. It is easy to replace the engine as long as the new engine works similarly to stockfish (majority do). Just copy into /data/engines and rename. Problem is, the ai is calibrated to the stockfish engine. So, performance will not tally with what is shown on screen. If you want the underlying concepts: I started the program because I wanted to teach chess to my niece and nephew and chessmaster was not up the task.”

• Ruby UCI - Universal Chess Interface for Ruby by Matthew Nielsen; supported engines ~ In theory it can support any UCI-compatible engine (except for conditions outlined in the 'caveats' section). It has been tested with: Stockfish (Jan 11 2013 Github source) - Fruit 2.3.1 (Mac); caveats ~ no move checking; this gem assumes the engine knows what it's doing; if the gem wishes to place a illegal move it will be accepted. Unix-style Line endings are assumed. Current version assumes unix-style (“\n”) line endings. That means running this under MS-DOS or Windows may barf. Very limited command set.

The following adapters will make many of the Chess GUIs above compatible with Winboard or UCI engines, but there is the possibility of introducing weird bugs, ie: well-behaved engines inexplicably may lose on time. It is recommended that you test thoroughly before using these adapters in 'official tournaments'.

Primary tools:

• Chess UCI Protocol Tracer Utility - A tool by Kannan Ramanathan, an UCI-only equivalent of InBetween. Disclaimer by the author: Note that this is not production ready code and meant to be used only for learning purpose.

• CombiChess by Tom Friederich - CombiChess a “chess engine” that combines 3 engines into one. It works by essentially asking 3 different engines what the they think is the best move for a given position, and then applying some logic to determine what move to actually do. After initial testing, it seems like it can easily beat the strongest of the 3 engines on its own. The rules that it uses are fairly simple: If 2 out of 3 engines give the same best move, then do that move and cancel work of the third - if all 3 engines say something else, listen to the 'Master engine'. The master engine is simply engine0 if all 3 engines agree, do that move.(actually, this never happens as work of the third engine is cancelled when the first two agree). For the best results, the 3 engines that are used need to be as equal in strength as possible. If one of the three is slightly better, it is best to use that one as master/engine0, since CombiChess listens to the master when all engines give a different result.
• HorviG Universal Chess Bot - trial version by nagyzolie that is compatible with Stockfish; commercial edition has much more features (UCI-support). First launch the WinBoard GUI in edit mode, then start HorviG. Hold down the mouse button for one second on the upper left hand corner of the board, and it will put a pink dot on the screen. Then hold down the mouse button for one second on the bottom right hand corner of the board, and it will put another pink dot on the screen, and then it will start playing immediately if you are playing as white, or it will wait until the opponent moves if it plays as black. It worked in a casual game on Lichess,too.
• JCPI - Java Chess Protocol Interface by Phokham Nonava provides a clean object-oriented interface to the UCI-protocol. It handles all the standard I/O communication and creates well defined Java objects for the engine to consume
• JSUCI - Javascript Universal Chess Interface by Edmund Moshammer is a port of UCI to Javascript. An interface for Javascript chess engines to the UCI (universal chess interface) protocol. This allows javascript chess engines to be launched in most chess graphical interfaces - CCC forum
• NodeUCI - An implementation by Buğra Fırat of the Universal Chess Interface protocol for node.js. In short, you can talk to engines (like Stockfish, Rybka, etc.) from node.js without any headaches. Abstracts away the pesky communication and parsing of UCI and provides a sane API to communicate with engines. The programmer´s declaration: “This is not a GUI or a program you can “open” to use an engine, this provides a library for communicating with UCI engines with the uci protocol. The programs you sent on that list all communicate through this protocol (this would be opaque to you as a user, the GUI handles it in the implementation). This project on the other hand is neither a GUI or an executable, it is a library to be used in other software programs (namely, javascript via node.js). In a sense, a GUI you can execute might use this project to communicate with the engine from behind the scenes. It seems to me you're looking to use an engine with a GUI, so this project is not a good candidate to do that. If you had some software (for example and automatic game analyzer) that needed to speak to an engine at some point, that would be the use case. This is just the library, so you can't execute anything without actually writing the code to do so.”
• Nucleus by Ferdinand Mosca; An engine adapter that can take 3 engines as a single engine. It will run slave1 and slave2 engines to determine the best move of the position, then run the master engine to decide which best move will be selected, either from slave1 or slave2 - cf. CCC forum - successor Aiquiri
• PyUCI - The Python UCI Chess Engine Interface (PUCEI or PyUCI) by Patrick Poitras allows communication with a UCI-enabled chess engine from Python 2.x on any platform (Linux / Macintosh / Windows systems etc.); project is in very early stages of development.
• Worse Chess by ecrucru - This script is an adapter between your chess GUI and your favorite UCI engine. The engine will play the N-th best move, or simply the worst move by pushing this logic to the limits. Either its prevent your strong engine from taking advantage of your blunders, or you desperately want to be checkmated by an engine that plays the worst move. Functionally, the script simply asks the UCI engine to analyze multiple variation lines. But instead of returning the best move, the adapter will check for an alternate line. Technically, it works with any classic/variant UCI engine that supports the option MultiPV with a value strictly greater than 1. For that, it is strongly recommended to have a multi-core CPU. The “strength of the weakness” is defined through the UCI option WorseChess_MultiPV_Limit. The higher, the slower and the weaker.

Thanks to Norbert Raimund Leisner for help in correcting this information and in finding many new GUIs for this page!
