history

The first versions of the program emerged from 1980 as school projects: Version 0.3 (March 1981) and 0.5 (March 1983) were written in BASIC and ran on a PDP-11 /70. From 1987 it was rewritten in the programming language C and developed by Uniacke on a part-time basis. In 1991 he won the amateur world championship for microcomputers with his program , in 1992 version 1.0 appeared for MS-DOS . Version 2.0 appeared in 1993; a slightly improved version 2.1 won the 12th microcomputer chess world championship in Munich in the same year . Version 3.0 was published in 1994, followed by version 4.0 in 1995. From 1996 onwards, HIARCS was marketed by ChessBase . Version 4.0 from 1996 was the first version for Microsoft Windows , and version 7.32 from 1999 was one of the first PC chess programs that could access Nalimov endgame databases while searching for moves . Version 11 published in December 2006, for which updates appeared the following year, was only available as a UCI engine for single and multi-processor systems via download, but not from ChessBase. This does not have its own user interface and can be operated under any interface that supports UCI engines, e.g. Fritz , Chess Assistant or Arena . Version 12 was released in March 2008 and is distributed both by download and again via ChessBase . Version 13 was released as a download in May 2010. Version 14 for Mac and Windows was released in August 2012 in conjunction with its own user interface, Chess Explorer .

Successes against human players

HIARCS took part in the AEGON tournament in The Hague several times in the 1990s, where human players competed against the best chess programs of the time. The program achieved a total of 18.5 points from 30 games. In 1997 version 5.0 was able to achieve a draw in two show games against the world-class players V. Anand and Jan Timman . In the same year, the newer version 6.0 was the first chess program to win a competition with tournament time against an international master when it won 4: 2 (3 wins, one loss, 2 draws) against Deen Hergott ( Elo 2395) in Ottawa . In games played over the Internet in 2002, Version 8.0 won against Boris Gulko 1.5: 0.5 and played 1: 1 against Ilia Smirin . In January 2003, an experimental version 8.196, which was released in the same year together with version 9.0, in a match in Maastricht against Yevgeny Bareev a 2-2. All four games ended in a draw. In 2005 a version of the program for Palm OS defeated several grandmasters , including Jan Gustafsson , in quick games .
