HIARCS Chess Software Pedigree: Origins, Evolution and Milestones

For over 15 years some of the best chess players in the world including multiple World Champions have been using HIARCS to prepare, analyse and play against. HIARCS is the result of 25 years active development by author Mark Uniacke and was the first PC chess program in history to win a match with an International Master (1996) and in 2003 it became the first chess program on a single processor to draw a match against a Super GM. In 2005 HIARCS on a Palm PDA became the first and only handheld chess program in history to defeat a GM in a match and in 2006 it was again the first and only handheld chess program to win a GM/IM tournament!   In 2008 our Pocket PC chess engine won the 2008 Mescusor Cup in Buenos Aires, Argentina ahead of Grandmasters scoring 8/10 in the process. This is a performance of 2691 Elo which is the best ever chess performance rating of a chess program on PDA in a Grandmaster tournament in history. Meanwhile its big brother HIARCS on PC and Mac was producing brilliant attacking chess to win a number of international computer chess tournaments and was top single computer in the World Computer Chess Championship in Beijing, China, Oct 2008. In August 2009, our Pocket PC chess engine went more than one step better by scoring an unprecedented and undefeated 9½/10 points (3 points clear of second placed Grandmaster) and 2938 Elo performance rating!  The greatest performance by any handheld chess computer in history.

"For me the Hiarcs brand is to PC chess what Mephisto was to dedicated - classy and a brand I trust." - Howard Deere

Recently a couple of customers posted these assessments of the HIARCS series of chess programs on a public forum, we think they nicely sum up what HIARCS is all about:

"...there is something that has been his [Hiarcs] monopoly, ever: style... The essence of Hiarcs style, if we still will use the word, is kind of an unrelenting, sharp, murderous, pitiless ability and hunger for blood... Hiarcs kills you as a guy jumping on you with a sword would do. No matter how good your position seems to be, how solid and ultra defensive, Hiarcs suddenly will find a corner to kick and put all your building in ruins. It is exhilarating to play it, more, lot more than with any other strong program. It is a real pleasure to be defeated that way. Fast, lightning, unexpected death."  - Fernando

"Hiarcs by Mark Uniacke comes in so many formats there is virtually no place you can't play a game against it. HIARCS is actually an acronym that stands for "Higher Intelligence Auto Response Chess System", and it truly lives up the name. In 1997, during his rematch with Deep Blue, Gary Kasparov had this to say about HIARCS: "HIARCS is much better positionally than Deep Blue." HIARCS also holds the longest standing reign for maintaining a top 5 rating in the World. It has the distinction of improving the most per version over the course of it's history as well. Oh.. by the way.. it's a World Champion as well."  - Peter Skinner

"If Hiarcs 11 is like a samurai that cut your head with a sharp blade in an instant, Hiarcs 12 is like a surgeon that extracts your brain from move 10. You simply do not see you are already dead... HIARCS 12 is even more dangerous, more vicious, more unstoppable. I am good enough not to fall in tactical mistakes, but Hiarcs does not need that to crush the opposition. Just a microscopic, a marginal imprecision, a matter of almost nothing and your fate is already written in the wall." - Fernando

Even the world's greatest ever player, Garry Kasparov, used HIARCS to prepare for IBM's Deep Blue 2!
