HIARCS Chess Engine for PC and Mac

World Chess Software Champion

HIARCS 14 UCI chess engines are available as part of HIARCS Chess Explorer for PC Windows and HIARCS Chess Explorer for Mac.

For more than 20 years ever since its first World Championship success in 1991 HIARCS has maintained its position as one of the world's premier chess playing programs. HIARCS is the current World Chess Software Champion having won the title in Tilburg, The Netherlands, November 2011.

HIARCS is famous for its human-like playing style and its ability to come up with the unexpected. HIARCS versions are renowned for sharp attacking chess and a never say die attitude to their play. In HIARCS 14 this playing style has been positively enhanced through a new deeper search and evaluation of dynamic possibilities. It is capable of building deep attacking positions against the enemy king and executing exciting mating attacks. This approach enables HIARCS to play interesting, distinctive aggressive chess while being sensitive to the needs of the position. This has improved HIARCS in all phases of the game and even in quieter positions HIARCS 14 is able to be more selective about the variations it explores to achieve a better understanding than previous versions leading to much stronger play.

As an analysis partner HIARCS is second to none with its ability to learn from the positions it analyses and plays. This is an essential feature for all chess players interested in analysing games, studies, positions and particularly the opening as it guides HIARCS into a greater understanding of chess positions and their possibilities than ever before. For many years top chess players have used HIARCS as an important analysis partner for this very reason.

This combination of strength, playing style and learning makes HIARCS 14 ideal for all players looking for an intelligent chess partner that learns and improves with you. A new super strong HIARCS 14 tournament openings book (in own/engine HCS format) is also included which has been dramatically enhanced with the latest cutting edge chess theory and a wealth of novelties to provide a huge repertoire of finely tuned variations accessible directly by the HIARCS chess engine.

Deep HIARCS 14 is the ultimate multi-core/multi-processor HIARCS chess engine capable of utilising up to 16 CPU cores simultaneously. This results in much faster analysis and playing strength depending on your hardware e.g. on Dual-Core hardware Deep HIARCS runs nearly twice as fast as on a single core processor. HIARCS also supports single core processor systems and even comes with a customer single core version so you can use it today in the knowledge it can grow with your new hardware to future proof your purchase decision.
