Commercial chess programs

I myself have only experience from Fritz 5.32, 6.0 and 7.0, Chessmaster 7000, 8000 and 9000, Shredder 10 and Rybka 4. If you want to learn more about the programs, go to the producer.

ChessGenius, which has been developed by Rickard Lang, is a very strong program, but it has not won any chess computer tournament since 1995. There is a demo version of Chess Genius Classic 7.

ChessGenius Classic7 is not compatible with the ChessBase platforms but has its own GUI. Eduard Nemeth describes how various chess engines can be installed in the GUI of Chess Genius 7. Languages: German and English.

ChessMaster is most likely the most sold chess program in the world - 4 million copies according to ChessMaster. It is a very strong program, but few professional players use it. There are other programs, which are more useful in storing and analyzing games. ChessMaster focus above all on graphics and a lot of gadgets, which are rather unimportant. But nobody can deny that the product is extremely elegant. The latest version is called ChessMaster 9000.

ChessPartner 5.3 exist in a demo version, which can be used in 30 days. ChessPartner does not belong to the strongest program and nor is it represented on the most important list as SSDF´s and Eric Hallswoth´s. ChessPartner has - despite it is a cheap program - a lot of functions, among other things you can connect to chess servers as ICC, FICS and

Chess Rk has been developed by Rksoft. Chess program with five levels of difficulty. Shareware – you can use it a limited number of times until you have to register and pay 15 dollar. It is not a bad program, but there are better ones, if you want a commercial program.

Chess System Tal II has at least previously been regarded as a strong program, which plays "human". "It has been constructed to play against other chess players (that is humans)", as the product information said. The program is not developed any more and is no longer represented on any rating list. The program was sold for a while by Purple Software under the name Purple Chess Champion and seem to appear in other disguises as well.

Chess Tiger, developed by Cristopher Therón, is a very strong program, which is sold by Lokasoft/Rebel. Chess Tiger 15.0 was ranked number five on the list of SSDF on May 26 2003.

Deep Sjeng 1.0 - this is a new program, that has been developed by Gian-Carlo Pascutto. The program, which comes with ChessPartner´s interface, is able to use 8 processors simultaneously. It is manufactured by Lokasoft.

EG (Earth Gaming) Chess is a surrealistic chess program. I would not buy this program in the first run. There is a demoversion, so anybody may evaluate the program.

Fritz, which is produced by ChessBase, is one of the absolutely best chess programs in the world. Fritz has often been ranked as number one on SSDF´s and Eric Hallsworth´s lists. The interface is very smart and is used by several other programs and engines. Now (2006) you can download the version 5.32. If you want to get to know commercial programs, this very strong program is recommended. Fritz 4.0 is installed as analysis engine in ChessBase Light and Fritz 6.0 exists in form of a demo version. Fritz 7.0 was released in October 2001. An important novelty was the opportunity to play free against other Fritz 7-users via the ChessBase server. Fritz 8 got a lot of new functions for the Chessbase chess server including more communications (email, chatting) improvements, new playing options and a player rating system - and finally a real working 3D chessboard. Fritz 8 played a draw, 4 - 4, against Kramnik in Dubai. The last version of Fritz is designated 9.0.

FXChess is a combined playing program and chess tutorial and besides adapted to Palm. Maybe this is Chess System Tal II in another disguise. Language: Spanish.

Gambit Tiger 2.0 is a version of Rebel Tiger, specialized in gambits. The programmer is Christopher Théron, but both these programs are produced by Schröder BV, which also produces Rebel. Gambit Tiger is a very strong program - number six on Eric Hallsworth´s list from 17/3 2003.

Gandalf, which has been devoloped by the Dane Steen Surballe, is a program which incessantly has climbed upwards on the rating list. The latest version has the designation 5.0 and is sold by Lokasoft/Rebel.

Goliath-Blitz by Michael Borgstädt is a commercial version, that is “powered” by Chess Academy Software. There are several free variants of Goliath, among others the chess engine Little Goliath and Goliath Mate, a mate solving program. Language: German.

Grand Master Chess - shareware program, which may be tested in fifteen days, and which later costs about $ 15. You can configure the design, vary different skill-levels and use a three-level hint. GMC also supports network gaming. The shareware version does not permit you to finish a game, but the playing strength is not too impressive.

Hiarcs is developed by Mark Uniacke and is one of the strongest programs in the world. The program is considered to play "human". Hiarcs uses Fritz interface. The latest version is designed 8.0.

Junior, developed by Amir Ban and Shay Basinsky, is also a leading program - different versions have been number one on certain lists and won some prestigous tournaments, for example the Computer Chess World Championships in 2001 and 2002. As we all know, Junior played 3-3 against Kasparov in a match in New York in January 2003. Junior uses the same interface as Fritz and is sold by ChessBase. The latest version has the designation 8.0.

Kasparov Chessmate may be installed on a PC or a PDA. The program is described as a multiplatform. The program should also be able to function as a client for online chess games.

Kchess Elite is an Australian program. Alike ChessPartner it is not especially strong and is not represented on the most important lists. There is a demo version.

Ktulu is a strong engine, which has been developed by Rahman Paidar from Iran, using the ChessPartner GUI.

Majestic Chess – the advance publicity once promised a chess engine, made by the same person who constructed the ChessMaster engine. The graphics resembled that of ChessMaster too. The program was reviewed by Game Spot in 2003. Presumably the program was not a hit, but you can still buy the program at for about 10$.

M-Chess Pro 8 was developed by Marty Hirsch and was also a strong program with its own interface. It is no longer developed. Also it is probably very difficult to get hold of the program anymore. Marty Hirsch is by the way technical director at World Chess Network, a playsite with big potential. The link went previously to Gambit-Soft, a firm, that does not exist anymore.

Nimzo, which is developed by Christian Donninger, is also a very strong program belonging to the ten best programs in the world. The last version has the designation 8.0, uses Fritz interface and is sold by ChessBase.

Rebel belongs absolutely to the ten strongest program in the world.. The latest versions are Rebel 10 and Rebel Century 4.0. Ed Schröder has also the nice habit of releasing a free version of Rebel on the net, as fast as he has developed a new version of Rebel. Rebel Decade 3.0 is for example a free version of Rebel 9 and plays with full strength on Fridays. I recommend Rebel 3.0. Beside the home page is very well designed and contains a lot of product information.

Ruffian is a strong chess engine constructed by Per-Ola Valfridsson. Already the first free version, 1.0.1, immediately took a place among the 20 best chess programs on the SSDF list. Ruffian 2.0 is now sold with different interfaces, with the Arena interface by Schachvertrieb Niggemann and with the ChessPartner interface by Lokasoft.

Rybka is a very strong chess engine, programmed by Vasik Rajlich. It is nowadays sold with the ChessBase interface. Rybka was for a long time number one on the rating lists, but it is now surpassed by Houdini.

Shredder, which has been developed by Stefan Meyer-Kahlen, is a very strong playing program. It has won the World Computer Chess Championships no less than eight times and the program is often top of the SSDF list. The homepage of Shredder 3, which won the WCCC 1999 (International Paderborn Computer Chess Championships) is still on Internet. The latest version is designated 8.0 and you can get the classical interface as well as the Fritz interface. You can download Shredder with the classical interface from Chess with Shredder for a trial. See also information about Shredder by ChessBase.

Amateur programs

All these programs use their own interfaces (that is chess boards). If you as an amateur wants to defeat a chess program, there is no sense in playing against the best commercial programs, because they play as good as a Grand Master. On the other hand it is possible to beat many amateur programs, but hardly programs as Comet or Crafty.
