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. The first version of HIARCS was written in 1980 in PDP-11 Basic, when Mark Uniacke was only 15 years old.
