8080 Chess, a chess program by Robert Arnstein for S-100 bus microcomputers, consisted of the pins of the Intel 8080 run out onto the backplane. It was commercially marketed in the 70s by Processor Technology Corporation. The 8080 Chess manual is still available online. 8080 Chess was the first microcomputer to participate in an ACM North American Computer Chess Championship, the ACM 1977 ^[1]. It further played the Second West Coast Computer Faire Microcomputer Chess Tournament in March 1978 ^[2].

Alexs

GerdIsenberg — Thu, 07 Dec 2017 22:26:51 GMT

Home * Engines * Alexs

Alexs,
a chess program by Alex van Tiggelen, apparently an application of ALEXS (Automatically Learning EXpert System), a neural network approach with a learning efficiency beyond of genetic learning, as elaborated and demonstrated by Van Tiggelen and Van den Herik at Advances in Computer Chess 6 in the domain of specific endgames, in particular the endgame of two knights versus h-pawn ^[1], and by Van Tiggelen casted to the middlegame ^[2].

Alexs played the DOCCC 1996 and the DOCCC 1998, according to Vincent Diepeveen ^[3] ^[4] it was based on the Dutch Nightmare by Joost Buijs, with an automatically tuned evaluation in 1996, but manually tuned parameters in 1998. A time-served version of Alexs was commercially available through Gambit-Soft from 1999 ^[5].

Home * Engines * Alfil

		AlfilChess, (Alfil Chess, Alfil) a chess program by Enrique Sánchez Acosta, written in C++, first incorporated as chess engine of TotalChess 2000, and subsequently since 2001 commercially released as Alfil Chess I and Alfil Chess 2.2 by Hollywood Publishing ^[1]. Alfil has become a free engine under Windows, compliant with UCI, and under Linux, compliant with the Chess Engine Communication Protocol. More recent versions have a parallel search with multiple threads and are able to probe Nalimov Tablebases ^[2], and were ported to Android ^[3].
Alfil for Android ^[4]

C# Engine Project

The C# Engine Project, at first dubbed Alfil 15 and released as open source in 2015, started from Stockfish v5 and various C# ports such as Portfish, and over the time incorporated ideas and knowledge gained from over 10 years of Alfil development, and from other open source engines ^[5]. Alfil 15 was registered for TCEC Season 8, when it was disqualified after its first game versus Pedone, since it could not disable its internal book, not complying with the TCEC rules ^[6]. After that incident, and due to discussions on Alfil's 15 origins in computer chess forums ^[7], the author made these more explicit on September 02, 2015, renamed the program, and invited everyone to collaborate ^[8].

Bogol

GerdIsenberg — Mon, 02 Jan 2017 09:55:38 GMT

Home * Engines * Bogol

		Bogol, a series of exclusive dedicated chess computers, developed and manufactured in the early 80s by the German Omikron Electronic GmbH ^[1]. It was Germany's second chess computer in 1981/82 after the Mephisto by Hegener & Glaser, and was supported by the West German Federal Ministry of Education and Science ^[2], but only released in small quantities and prototypes. The computer's name was in remembrance to chess grandmaster Efim Dmitriyevich Bogolyubov. The 6502 processing unit with a program by Olaf Schinkel and the sensory chessboard were seperate units, connected via cable. The Bogol 5.0 prototype, which had reversed square colors, played a strong European MCC 1982 represented by the Omikron team of Martin Suhl and Gerd Krey. Despite missing the first round and losing by default, Bogol managed 4 out of 7 ^[3] ^[4] . According to Hans-Peter Ketterling, the Bogol 5.0 was never realeased to the market, apparently due to its close relation to another chess computer ^[5] .

Boris

GerdIsenberg — Mon, 25 Dec 2017 18:54:06 GMT

Home * Engines * Boris

		Boris, an early dedicated chess computer, which appeared in February 1978, designed and manufactured by Applied Concepts ^[1] and marketed by primary distributor Chafitz. Already in March 1978, Boris played Second West Coast Computer Faire Microcomputer Chess Tournament in the "microcomputers with less than 8K of memory class" ^[2]. The name was likely in dependence on the given name of Boris Spassky, who lost the Chess World Championship 1972 from Bobby Fischer in Reykjavik. Boris ran on a Fairchild F8 8-bit microprocessor with only 2.5 KiB ROM and 256 byte RAM. David Lindsay was hired to program the machine ^[3], and two further Boris models with Lindsay programs appeared in 1979, the first travel chess computer Boris Diplomat ^[4] ^[5], where Lindsay holds a patent ^[6] on the Chess piece font ^[7], and the Boris Master ^[8].

Bobby Fischer calling

Steve Chafitz on a call from Bobby Fischer ^[12]:

Just to rewind a bit, one evening when I was home having dinner, I got a call from Bobby Fischer. He was excited about our electronic chess game "Boris" and I realized that if he was interested in our electronic chess game that there was a major market out there. We increased our development of electronic games and yes, we hired the brightest and the best programmers in the country to develop programs for our games.

Co-Author

The ICGA site mentions Rex Kent as author of Boris Experimental which played the 1st World Microcomputer Chess Championship 1980 in London ^[13]. However, Boris X was already the work of Kathe and Dan Spracklen, and additionally with modifications by John Aker and Terry Fredrick. Rex Kent operated Boris at the PCW-MCC 1978 ^[14]. It is a bit unclear whether Kent was operator or co- or book-author of the early Boris otherwise credited to David Lindsay.

Boris 2.5

In 1979, following the development of the original Boris when more advanced programs were required, Arleen and Steve Chafitz contracted Kathe and Dan Spracklen to be their chess programmers for their Chafitz modular game system as well the Applied Concepts Great Game Machine ^[15]. Their Sargon 2.5 program appeared as Chafitz Sargon 2.5 MGS module ^[16], and in 1980, as Chafitz ARB Sargon 2.5 ^[17], also called Boris Sargon 2.5 ^[18] or simply dubbed Boris 2.5. John Aker and Terry Fredrick, affiliated with Applied Concepts, were involved in improving the Sargon and Boris program ^[19].

Boris Handroid

		Boris Handroid was the first but very rare electronic chess robot from 1980 ^[20], with 64 Hall effect sensors to recognize pieces, and three servomechanisms to control the cartesian robotic arm. The Handroid program, adapted by Terry Fredrick ^[21] was also based on Sargon 2.5 by Kathe and Dan Spracklen.
Handroid ^[22]

Boris Experimental

Boris Experimental (Boris X) was the further development of the Boris 2.5 aka Sargon 2.5 program, but no longer by the Spracklens, who after their experience no longer worked for Chafitz, but for Samole's Fidelity Electronics. John Aker continued the job.

WMCCC 1980

The Sargon based Boris Experimental played the 1st World Microcomputer Chess Championship, September 4-9, 1980, in London, where it only lost versus later champion and Sargon based Challenger X, blundering an endgame a piece up ^[23], and became second with 4 out of 5!

Controversy

ACM 1980

Boris X was also registered for the ACM 1980. A brief description is given in the tournament booklet with Applied Concepts CEO Alan Mead as representative ^[24] :

BORIS EXPERIMENTAL, Alan Mead, Applied Concepts, Garland, Texas

The program uses alpha-beta pruning with recently developed and improved search heuristics. The program runs in 8k of program space and has nine levels of play including two tournament levels. The tournament level play is expected to be 100 points stronger than the present BORIS 2.5 program.

But Boris X, despite registered, finally did not play the ACM 1980. Kathe Spracklen had filed a protest, claiming Boris X is too similar to Sargon 2.5, and requested mutual comparison of the source code. After John Aker admitted that Boris X was a revamped Sargon 2.5, Boris was rejected ^[25] ^[26].

ACM 1981

At the 12th ACM 1981, Boris X was mentioned in the booklet again, now with a long list of its authors and Applied Concepts representatives ^[27], but again, did not participate, likely also because David Slate was already competing with Nuchess:

BORIS EXPERIMENTAL, John Aker, Alan Mead, Terry Fredrick, John Jacobs, David Slate, Larry Atkin (c/o AM, Applied Concepts, Inc. 207 N. Kirby, Garland, Texas 75042), Great Game Machine (at site)

Cassia Chess Mate and relatives, such as the CXG Computachess I in 1981 were clones of Ron Nelson's Fidelity Chess Challenger 10 ^[3] ^[4]. While the CXG Computachess I was stopped from shipping into the US, it seems the Chess Mate was further shipped to Europe ^[5], according to Ron Nelson, with an operating manual logo looking like the CXG Computachess one ^[6].

Check Check,
a commercial chess program by Wolfgang Delmare, developed in the late 80s and early 90s. It was a 16-bit 8086 and later 32-bit x86 program running on PCs under MS-DOS with a pleasant GUI. Check Check played the Tenth World Microcomputer Chess Championship 1990 in Lyon, and the first three International Paderborn Computer Chess Championships, IPCCC 1991, IPCCC 1992, and IPCCC 1993, and was the first commercial chess program using own three and four men Endgame Tablebases, spending the "huge" amount of 16MB hard disk space.

Chess Challenger

GerdIsenberg — Wed, 27 Dec 2017 12:49:08 GMT

Home * Engines * Chess Challenger

		Chess Challenger, or Fidelity Chess Challenger, was a series of dedicated chess computers produced and market by Fidelity Electronics. The Chess Challenger 1 was the first commercial chess computer of its kind in 1976, invented by Sidney Samole, with a program by Ron Nelson, developed for an Altair 8800 Microcomputer with an Intel 8080 CPU. Further versions of Nelson's program run on a more advanced Z80 CPU, great commercial success was the Chess Challenger 7 ^[1] in 1979. Ed English, an early game programmer affiliated with Fidelity Electronics in 1979/80, improved the alpha-beta implementation to double the playing speed ^[2].

Sargon becomes Challenger

In 1980, when Dan and Kathe Spracklen started to collaborate with Samole, a 6502 Version of Chess Challenger was built for a Sargon III port. The 6502 was better suited for Sargon than Z80. Excerpt from their oral history how it went with Fidelity ^[5] :

So, that’s about the time we started looking at Fidelity again. We got in contact with Sid Samole, who was the President of the company, and he said, “Well, come out and see us and bring your- what you got out there and show it to us.” And so we got on a plane and flew out to Miami, and showed off our program to him. And they had their chief engineer, Ron Nelson, look at it, and they were impressed. And so they offered us a big contract, basically, to go to work for them, basically, fulltime. And we didn’t have to go to Miami. We could stay in San Diego.

They had the Chess Challenger 1, I think, out at the time, or 2, and they were looking for something better. Our program, that we brought with us, just shellacked their program. We had a little tournament there, in Miami, just a little, between us, on our- the one we brought with us. And they were impressed.

And we continued to sell both through, or Sargon, through Hayden. So Fidelity didn’t mind that. The said that’s cool. They didn’t see it as a competition with them.

WMCCC 1980, MCC 1980

The immediate success was the lucky win of the 1st World Microcomputer Chess Championship, September 4 to 9, 1980, in London. Chess Challenger with a 6502 CPU, notably winning last three of five rounds against three of four other Sargon incarnations! While the ICGA tournament site states a Z80A CPU ^[6], Kevin O’Connell reported the World Microcomputer Chess Champion was equipped with a MOS Technology processor, despite newest Fidelity computers were shipped with Z80/Z80A ^[7]. As further confirmed by Fidelity Electronics' Vice President Myron Samole in an Personal Computing interview, the Champion Sensory Challenger, which also won the MCC 1980 at September 5 to 7 in San Jose, California had a program written around the 6502 chip ^[8].

German Chess Challenger brochure with Prof. Heinz Haber endorsement ^[9]
Chess Challenger Sensory Voice ^[10], a Z80 based Nelson Program as Micro Champ? ^[11]

WCCC 1980

The Chess Challenger which played the WCCC 1980 end of September in Linz and finished last was presumably an older Z80 based computer with a Nelson program ^[12]. Fidelity's flagship end of the 70s, with World Champion 1980 advertisement was the Chess Challenger Sensory Voice. The first 6502 based computer with a Spracklen program commercially available appeared in 1981 as Champion Sensory Chess Challenger ^[13] .

ACM 1980

The strong third place at the ACM 1980 in October was again a great success, only losing to Belle in the last round ^[14]. Description given from the ACM booklet with mentioned authors Dan and Kathe Spracklen, Ronald Nelson, Frank Duason ^[15]

This marks the first appearance in an ACM tournament for this popular machine. Chess Challenger is written in assembly language for a 6502 microprocessor. It has 20k bytes of memory and executes about 1,000,000 inst/sec. A book of about 1,000 moves is used. The program uses the alpha-beta algorithm with iterative deepening.

Name Confusion

Using the same name at almost the same time for programs with different authors and CPU architectures caused some confusion by potential customers, not to mention tournament organizers. Accordant to their product lineup and nomination, and caused by former tournament rules, permitting multiple, but different named entries from the same author, and commercial availability of participating computers, Fidelity Electronics somehow was "forced" to continue the naming obfuscation in further tournaments, where Fidelity computers with Spracklen programs participated as Fidelity X, Challenger-X, Elegance, Elite, Private Line, and Sensory.

Chess Challenger X

ACM 1986

In 1986, at the 17th ACM North American Computer Chess Championship, Fidelity showed up with a huge experimental, parallel machine, named Chess Challenger X. Authors were Ron Nelson, Dan Spracklen, Kathe Spracklen, and Danny Kopec as Book author. It had a Z80 controller, and 16 or more 68000 16-bit processors. The controller was written in C, the 16 or more Spracklen programs in assembler ^[16].

Chess Challenger X scored 50%, losing from Recom and Belle. Notably, in the same tournament, another Fidelity computer programmed by the Spracklens with a Kopec book took part, as Fidelity Experimental with a 68020 processor. It did not score better in that strong field and finally placed 10th.

ACM 1988

At the ACM 1988, the new experimental version of a 68030 based micro called Chess Challenger X showed a remarkable performance. Mentioned authors from the tournament report by Monty Newborn and Danny Kopec ^[17] were Dan and Kathe Spracklen as well as Ron Nelson. The 32-bit program, written in 68030 assembly language, drew Deep Thought and won versus Waycool, the current World Champion Cray Blitz, and HiTech. Chess Challenger X was likely the forerunner of the commercial available Fidelity Elite Avant Garde V9 ^[18] . One year later, at the WCCC 1989 in Edmonton, a similar machine, presumably with a further developed program, played under the name Fidelity X and finished sixth.
