The HIARCS 10 opening book is significant step forward in chess opening books. It was developed by Eric Hallsworth and Mark Uniacke and is finely tuned with a huge variety of novelties and cutting edge opening theory. The opening book is one of the few books left which is hand edited and is optimised for the HIARCS style of play.
Unlike most other opening books this book is NOT just a book of GM games extracted from a database. Such books are prone to errors and rarely contain novelties or refutations to established theory. For this reason the Hiarcs 10 book has been hand tuned with the help of a world class chess player (who will remain nameless) and is therefore of great value to chess players because it gives them a valuable resource which can be used in practical terms to improve their own repertoire.

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