Schach

one of the early German chess programs, written by Matthias Engelbach since 1978 in Algol while affiliated with the [|Bundeswehr University Munich]. Schach **2.0** was based on a 1970 version of the Fortran program Schach by Rolf C. Smith and Franklin D. Ceruti (Version 1 was the 1968 Master's thesis that originated from [|Texas A&M University]). In the early 90s, Thomas Kreitmair joined as co-author, starting to re-write Schach in x86 assembly. || toc =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 language for DOS PCs. It was one of the fastest programs of its time. Schach **3.0** played seven Dutch Open Computer Chess Championships from 1991 until 1997, and became strong third at the DOCCC 1994. Further, Schach played four IPCCCs winning IPCCC 1994, the PC Division of Don Beal's UPCCC 1992 and UPCCC 1993, five Aegon Tournaments from 1993 until 1997, and three ICCA tournaments the WCCC 1995, the WMCCC 1995, and the WMCCC 1996.
