Background

Each HIARCS product comes with its own chess opening book with the latest chess opening theory at the time of the release of the particular product. However, many chess players need to remain up to date with the latest chess opening theory throughout the year and online chess engine players like to have the latest and strongest chess opening book.

For many years HIARCS has had the strongest opening book available and it keeps getting stronger with every release. We even supplied the HIARCS tournament chess opening book to help World Chess Champion, Vishy Anand's team prepare for his World Championship matches.

We now find our book is sought after by many of world's strongest players and is an essential additional resource for the serious chess player.

The latest HIARCS tournament opening book is available in Chessbase CTG format (for PC), HIARCS' own HCS format for Mac and PC with regular updates for subscribers to the HIARCS Chess Opening Book Subscription product. Improvements per year have averaged about 80 Elo points. Over the course of a year the opening book may contribute more to chess strength improvement than the increase in chess engine strength.

"I subscribe to your Powerbook now and I'm pretty impressed by it, I use it all the time in my chess teaching. As far as I know it is the best publicly available book."
Larry Kaufman, Grandmaster and World Senior Chess Champion.

"I have tried the book in several configurations. Means in autoplayer, games at home, at FICS chess server and at playchess. I am very impressed. My feedback: This book is a masterpiece ! Congratulations" - Clemens

"I agree. Clearly a lot of work has been put into this book to provide strength in depth so the openings hold up in different time control games.
Excellent value for money in its own right but with a quarterly update ... just superb."
- PeterG
