In April 1997, HIARCS 6.0 became the first PC chess program to win a match played at tournament time controls over a FIDE International Master.

In 1991, it won the title of the World Amateur Microcomputer Chess Champion at the 11th World Microcomputer Chess Championship (WMCCC), in 1992, it won the gold medal at the 4th Computer Olympiad, and in 1993, it won the World Microcomputer Chess Championship held in Munich. HIARCS has won numerous computer and human tournaments.

Since Version 14, released in August 2012, HIARCS has been sold along with its own GUI (Chess Explorer) available on Mac OS X and Windows. HIARCS 12.1 and 13 are the engines in Pocket Fritz by Chessbase. Version 11, the first version to support multiprocessing, was released in December 2006. In 1996, Hiarcs 4.0 became the first version to be marketed by Chessbase sold inside the Fritz GUI. In 1991, Hiarcs went commercial and Hiarcs 1.0 was released for PCs and the MS-DOS operating system. Īt the end of the 80s, HIARCS was rewritten in C, and soon competed in computer chess tournaments. This resulted in a program that relied on positional algorithms, rather than search depth. To compensate for this, Mark developed some heuristics to guide the program's search and evaluation in a more 'targeted' way. Subsequent versions were also written in interpreted Basic, which meant that the program was rather slow. I think that Hiracs uses the experience and (general) knowledge of the former X-Chess developer.The first version of HIARCS was written in 1980 in PDP-11 Basic, when Mark Uniacke was only 15 years old.
