ChessBase is a German company that develops and sells chess software, maintains a chess news site, and operates an internet chess server for online chess. Founded in 1986, it maintains and sells large-scale databases containing the moves of recorded chess games.[1][2] The databases contain data from prior games and provide engine analyses of games. Endgame tablebases are also provided by the company.[3]
ChessBase's Indian YouTube channel ChessBase India has amassed more than 1.2 million YouTube subscribers and more than 1 billion total views as of August 2023.[4]
History
Starting in 1983, Frederic Friedel and his colleagues put out a magazine Computer-schach und Spiele covering the emerging hobby of computer chess. In 1985, Friedel invited then world chess champion Garry Kasparov to his house. Kasparov mused about how a chess database would make it easier for him to prepare for specific opponents. Friedel began working with Bonn physicist Matthias Wüllenweber who created the first such database, ChessBase 1.0, as software for the Atari ST. The February 1987 issue of Computer-schach und Spiele introduced the database program as well as the ChessBase magazine, a floppy disk containing chess games edited by chess grandmasterJohn Nunn.
The August 1991 issue of Computer-schach und Spiele announced that Dutch programmer Frans Morsch's Fritz program would soon be available for purchase as software for PCs. This method of software sale was unlike all the dedicated chess computers which at the time dominated the ratings lists. This program was marketed initially as Knightstalker in the U.S., while it was marketed as Fritz in the rest of the world. Mathias Feist joined ChessBase, and ported Fritz to DOS and then Microsoft Windows.
In 1994, German chess grandmaster Rainer Knaak joined ChessBase as a full-time employee, annotating games for the ChessBase magazine, and soon authoring game database CD-ROMs on topics such as the Trompowsky Attack or Mating Attacks against 0-0. British grandmaster Daniel King was another early author of such CD-ROMs which eventually grew into the Fritztrainer series of multimedia DVDs.
In the mid-1990s, R&D Publishing in the U.S. released a series of print books in the ChessBase University Opening Series, including Karpov and Alexander Beliavsky's The Caro-Kann in Black and White.
In December 1996, ChessBase added Mark Uniacke's Hiarcs 6 chess engine to its product line up, selling it inside the existing Fritz graphical user interface (GUI).[5] In March 1998, ChessBase added Junior 4.6 and Dr. Christian Donninger's Nimzo99.[6] Also that year, ChessBase released Fritz 5 including a 'friend mode' which would automatically scale its strength of play down to the level that it assessed the player was playing.[7] This remains a feature of all of ChessBase's Graphical User Interfaces.
In 1998, ChessBase took their database of chess games online.[8] In November, ChessBase started offering trainer CD-ROMs by such grandmasters as Robert Hübner, Rainer Knaak and Daniel King.[9]
In 1999, Stefan Meyer-Kahlen's Shredder had won the world computer chess championship. In April, Meyer-Kahlen and Huber released the Universal Chess Interface (UCI) protocol for engines to communicate with GUIs, to compete with Winboard and ChessBase. Meyer-Kahlen's contract with Millennium 2000 expired in June, and ChessBase hired him shortly after, adding Shredder to their product line under a Fritz style GUI, and giving their new GUIs the ability to import UCI engines.[10]
In April 2000, ChessBase released a Young Talents CD featuring the engines Anmon, Goliath Light, Gromit, Ikarus, Patzer, Phalanx and Rudolf Huber's SOS. Christophe Theron's engines Chess Tiger and Gambit Tiger were also released as ChessBase engines that month.[10]
In 2003, ChessBase introduced the Chess Media System, allowing players to produce videos with them playing out moves that can be seen on the user's chessboard within a ChessBase program. Eventually, ChessBase commissioned world champions Garry Kasparov, Viswanathan Anand, Vladimir Kramnik and Rustam Kasimdzhanov to produce DVDs using the new format. ChessBase also produced Fritztrainer Opening DVDs by the likes of grandmasters Alexei Shirov and Viktor Bologan and a Power Play series by British grandmaster Daniel King for lower level players.
In April 2006, following its victory at the World Computer Chess Championship, Anthony Cozzie's Zappa chess engine was published by ChessBase as Zap!Chess.
Recent versions of ChessBase and the engine GUIs such as Fritz supports cloud engines. ChessBase/Playchess added a web interface by 2013.[11] ChessBase added a tactics trainer web app in 2015.[12] In 2015, ChessBase released a play Fritz web app,[13] as well as My Games for storing one's games.[14]
The company
The company is located in Hamburg, Germany. ChessBaseUSA[15] markets their products in the United States, and some of their most popular programs are sold by licensee Viva Media, a division of Encore, Inc. In 1998, the German company Data Becker released the program 3D Schach Genie, containing the Shredder engine and Fritz interface. ChessBase India markets their products in India and surrounding countries. ChessBase India is run by International Master(IM) Sagar Shah and his wife Amruta Mokal.[16]
The database
ChessBase was originally designed for the Atari ST by Matthias Wüllenweber, the physicist/co-founder of the company. Mathias Feist helped port the program to DOS. In more recent years, Lutz Nebe, Wolfgang Haar and Jeroen van den Belt have also been involved in program development.

ChessBase uses a proprietary format for storing games (CBH), but can also handle games in portable game notation (PGN). The proprietary format uses less hard drive space and manages information that is not possible in PGN. The software converts files from PGN to ChessBase format, or from ChessBase to PGN.
The program permits searches for games, and positions in games, based on player names, openings, some tactical and strategic motifs, material imbalance, and features of the position. ChessBase can import engines either those such as Fritz or Shredder in native ChessBase format or Universal Chess Interface (UCI) engines such as Stockfish.
As of 19November2020[update], ChessCase's database contained over 8.4 million games.[17] The online database can be accessed directly through their database programs.
Playchess is an internet chess service where players can play chess with other players and discuss about chess.[18]
News site
ChessBase also maintains ChessBase News, a web site containing chess news, as well as information on their products. The site is available in English, German, Spanish and Hindi.[19]
Other publications
ChessBase produces CDs and DVDs, including monographs on famous players, tactical training exercises, and training for specific opening systems. They publish the ChessBase Magazine six times per year, which comes on DVD with video clip interviews, articles on opening novelties, database updates (including annotated games), and other articles. All these are designed for viewing within their database software or the free ChessBase Reader.

A database-only version of ChessBase for the BBC Micro, called "BBChessBase", was published by Peter Tate in 1991.[20]
Gerritt Reubold's Der Bringer chess program is a rare example of a ChessBase format engine not released by ChessBase itself.[21]
Criticism and legal issues
ChessBase has faced criticism for allegedly using free software created by others without credit. The developers of Stockfish, an open-source chess engine, charged that Fat Fritz 2 is a modified copy of their software (that had originally been uncredited; since rectified) and that ChessBase claims "originality where there is none".[22]Lichess described the same product as "a rip-off".[23]
ChessBase responded to this criticism by adding references but claiming the new engine differs from Stockfish due to added input from the original Fat Fritz neural network[24]—itself claimed by Lichess to be derived closely from Leela Chess Zero, another open-source initiative.[23]
In July 2021, Stockfish sued ChessBase, alleging that ChessBase violated Stockfish's GNU General Public License.[25] In November 2022, a settlement on that lawsuit was reached.[26][27]
Fischer random chess, also known as Chess960 and freestyle chess, is a variation of the game of chess invented by the former world chess champion Bobby Fischer. Fischer announced this variation on June 19, 1996, in Buenos Aires, Argentina. Fischer random chess employs the same board and pieces as classical chess, but the starting position of the pieces on the players' home ranks is randomized, following certain rules. The random setup makes gaining an advantage through the memorization of openings impracticable; players instead must rely more on their skill and creativity over the board.
Computer chess includes both hardware and software capable of playing chess. Computer chess provides opportunities for players to practice even in the absence of human opponents, and also provides opportunities for analysis, entertainment and training. Computer chess applications that play at the level of a chess grandmaster or higher are available on hardware from supercomputers to smart phones. Standalone chess-playing machines are also available. Stockfish, Leela Chess Zero, GNU Chess, Fruit, and other free open source applications are available for various platforms.

Correspondence chess is chess played by various forms of long-distance correspondence, traditionally through the postal system. Today it is usually played through a correspondence chess server, a public internet chess forum, or email. Less common methods that have been employed include fax, homing pigeon and phone. It is in contrast to over-the-board (OTB) chess, where the players sit at a chessboard at the same time, or play each other in real time via the internet.
The Universal Chess Interface (UCI) is an open communication protocol that enables chess engines to communicate with user interfaces.

Opening book is often used to describe the database of chess openings given to computer chess programs. Such programs are quite significantly enhanced through the provision of an electronic version of an opening book. This eliminates the need for the program to calculate the best lines during approximately the first ten moves of the game, where the positions are extremely open-ended and thus computationally expensive to evaluate. As a result, it places the computer in a stronger position using considerably less resources than if it had to calculate the moves itself.
AlphaZero is a computer program developed by artificial intelligence research company DeepMind to master the games of chess, shogi and go. This algorithm uses an approach similar to AlphaGo Zero.
