HIARCS 10 UCI +
A chess program that can do more than calculate!

Please note existing HIARCS UCI owners can update to the new faster and stronger X54 32 bit and X54 64 bit engines for FREE now!

Hiarcs has long been renowned for its human-like playing style, now Hiarcs goes much further with improved chess knowledge, a more aggressive style and an ability to search very deeply for the truth of a position. New chess knowledge enables Hiarcs to identify deep attacking motifs long before they become apparent especially concerning king attacks and unbalanced positions and material. Hiarcs often prefers initiative and attacking options over more materialistic concerns associated with traditional chess programs. Matched to this new chess knowledge Hiarcs searches much more deeply than its predecessor often enabling it to find new unexpected moves and ideas much faster.

New enhancements mean that while playing or analysing games, Hiarcs is able to learn more about the positions and moves it sees to improve its chess strength in future games. This feature is essential for all chess players who analyse chess games, studies, positions and openings as it enables Hiarcs to understand deep strategic or tactical ideas while analysing with you. With Hiarcs you get an intelligent chess partner which actually learns and improves with you!

The new Hiarcs opening book is included which has been significantly enhanced with the latest GM theory and a wealth of novelties to provide a huge repertoire of finely tuned variations. This is the work of computer chess expert Eric Hallsworth and Hiarcs author Mark Uniacke who have combined to provide an exceptional new opening book. 

These features all add up to make Hiarcs an essential tool for chess players of all strengths making the chess games you play or analyse much more interesting, unpredictable and exciting than ever before.
