"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

"HIARCS is much better positionally than Deep Blue." - Garry Kasparov 1997 (after game 5 of the rematch)

For Palm, PC & Mac Chess Software with attitude, features and chess playing strength, you can't beat HIARCS!
