HIARCS Pedigree: Origins, Evolution and Milestones

HIARCS is the result of 18 years active development by author Mark Uniacke and was the first PC chess program in history to win a match with an International Master 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. Even Garry Kasparov used HIARCS to prepare for Deep Blue 2!

"I've been in the chess computer software biz for over a decade and I can tell you that I have never heard more raves from users over any other chess program than I've heard over Hiarcs. Users love this chess engine. I've received literally scores of highly favorable e-mails and comments from happy Hiarcs owners over the years. If you never buy another chess engine, you owe it to yourself to add Hiarcs to your stable of chess playing programs. Playing against Hiarcs is very much like playing against a strong human player." - Hiarcs 9 review by Steve Lopez 17/10/2003
