HIARCS is one of the few original PC chess programs still competing in top level chess competition. It has been in development over the last twenty years and since 1991 has always been among the top chess programs in the world. In this time it has led world computer rating lists and won World Championship titles. It was the first PC chess program to defeat a FIDE International Master in a match and has been a favourite of a number of World Chess Champions. So much so that [https://en.wikipedia.org/wiki/Garry_Kasparov Garry Kasparov] said towards the end of [[Kasparov versus Deep Blue 1997|his match]] with [[Deep Blue|Deep Blue2]] that "HIARCS is much better positionally than Deep Blue". HIARCS is available on a number of platforms including PC, Macintosh and handheld devices. The handheld Palm version has won multiple matches against GMs and even won a GM/IM tournament in the Philippines. HIARCS' playing style is now very aggressive with a distinctive liking for attacking the opponent's king. This often leads to dynamic exciting games which are often played on a knife-edge. HIARCS is now capable of taking advantage of multi-processors/cores to improve its chess performance making it a very dangerous opponent.
