Special thanks to Ole Christensen (Sigma Chess) for his superb Sigma Chess software, quite simply the best chess GUI for the Macintosh.
A big thank you to Richard Fowell for his superb beta testing and suggestions without which this product would not be what it is today. Richard has helped test HIARCS Mac versions since the first HIARCS chess product for the Macintosh way back in 1995 and his detailed knowledge and thorough testing is truly outstanding.
Finally many thanks to David Gill for his excellent contribution to beta testing Sigma Chess HIARCS.
These people have helped make the product the best it could be. THANK YOU!
