'''Schach''', (Schach '''2.x''' and '''3.0''')<br/>
one of the early German chess programs, written by [[Matthias Engelbach]] since 1978 in [[Algol]] <ref>[http://www.computerhistory.org/chess/full_record.php?iid=doc-431614f6c9575 The Fifteenth ACM Computer Chess Championship, San Francisco California, October 7-9, 1984], [http://archive.computerhistory.org/projects/chess/related_materials/text/3-1%20and%203-2%20and%203-3%20and%204-3.1984_15th_NACCC/1984%20NACCC.062303012.sm.pdf pdf] from [[The Computer History Museum]]</ref> while affiliated with the [https://en.wikipedia.org/wiki/Bundeswehr_University_Munich Bundeswehr University Munich] <ref>[http://www.xing.com/profile/Matthias_Engelbach Matthias Engelbach - Profile], [https://en.wikipedia.org/wiki/XING XING]</ref> . Schach '''2.0''' was based on a 1970 version of the [[Fortran]] program [[Schach (US)|Schach]] by [[Rolf C. Smith]] and [[Franklin D. Ceruti]] (Version 1 was the 1968 Master's thesis that originated from [https://en.wikipedia.org/wiki/Texas_A%26M_University Texas A&M University]) <ref>[http://www.chessgames.com/perl/chessplayer?pid=64934 The chess games of Schach 2 3] from [https://en.wikipedia.org/wiki/Chessgames.com Chessgames.com]</ref> . In the early 90s, [[Thomas Kreitmair]] joined as co-author, starting to re-write Schach in [[x86]] [[Assembly|assembly]].
=Schach 2.x=
As its debut, Schach '''2.3''' participated at the [[WCCC 1980]], Schach '''2.5''' played the [[ACM 1981]], Schach '''2.6''' the [[ACM 1982]], and Schach '''2.7''' the [[WCCC 1983]], [[ACM 1984]], and finally the [[WCCC 1986]].
=Schach 3.0=
In the 90s, along with co-author [[Thomas Kreitmair]], Schach '''3.0''' was a complete re-write in [[x86]] (486) [[Assembly|assembly language]] for [[MS-DOS|DOS]] [[IBM PC|PCs]]. It was one of the fastest programs of its time <ref>[https://www.stmintz.com/ccc/index.php?id=222098 Schach 3.0] by [[Vincent Diepeveen]], [[CCC]], April 08, 2002</ref> . Schach '''3.0''' played seven [[Dutch Open Computer Chess Championship|Dutch Open Computer Chess Championships]] from [[DOCCC 1991|1991]] until [[DOCCC 1997|1997]], and became strong third at the [[DOCCC 1994]]. Further, Schach played four [[IPCCC|IPCCCs]] winning [[IPCCC 1994]], the PC Division of [[Don Beal|Don Beal's]] [[UPCCC 1992]] and [[UPCCC 1993]], five [[Aegon Tournaments]] from [[Aegon 1993|1993]] until [[Aegon 1997|1997]], and three [[ICCA]] tournaments the [[WCCC 1995]], the [[WMCCC 1995]], and the [[WMCCC 1996]] .
=Description=
given in 1995 from the [[ICGA]] site <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=187 Schach's ICGA Tournaments]</ref> :
Schach 3 is the PC version of Schach 2.x one of the earliest German chess programs. It is a non-commercial project developed and maintained by two former students. Work on Schach started in 1978 and after some surprisingly good results in computer chess tournaments, the authors could not stop working on the program. Even the distance - one of the programmers (Kreitmeir) lives in the Netherlands and the other in Germany - is no real handicap.
The program is a more or less simple [[Type A Strategy|Shannon-A]] program with all the known extensions (the authors believe in the [[Brute-Force|brute-force]] method for computer chess). The program is written in 486- assembler and can search 9 or ten plies in the [[Middlegame|middlegame]]. Schach participated in the 1980, 1983 and 1986 World Championships, in the ACM events in the period 1981-1985 and in the German and Dutch Championships since 1992. Best results were a 6th place in Linz 1980 and New York 1983, a 3rd place in the 1994 Dutch Championship and a first place in the 1994 German Championship ([[Zugzwang (Program)|Zugzwang]] was absent, but we all need some good luck!)
