HIARCS Chess Opening Books

Each HIARCS chess product comes with its own digital 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 books.

For many years HIARCS has had the strongest opening books available and it keeps getting stronger with every release. We even supplied the HIARCS tournament chess opening book to help five time World Chess Champion, Vishy Anand's team prepare for his World Championship match in which he was so successful.

We now find our books are sought after by many of world's strongest human players for both over the board and correspondence play - an essential resource for the serious chess player.
