HIARCS 13 UCI
Single and Multi-core/processor versions available NOW
A chess program that can do more than calculate!

For 20 years HIARCS has been among the very best chess programs in the world. Ever since its first World Championship success in 1991 HIARCS has maintained its position as one of the world's premier chess playing programs. As recently as June 2009 HIARCS further enhanced its reputation by winning the 9th International CSVN Tournament in Leiden, The Netherlands.

HIARCS is famous for its human-like playing style and its ability to come up with the unexpected. Recent HIARCS versions are renowned for sharp attacking chess and a never say die attitude to their play. In HIARCS 13 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 new 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 13 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 13 ideal for all players looking for an intelligent chess partner that learns and improves with you. A new super strong HIARCS 13 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.

The HIARCS 13 MP version 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 HIARCS 13 MP runs nearly twice as fast as on a single core processor. HIARCS 13 MP even works on single core processor systems so you can use it today in the knowledge it can grow with your new hardware to future proof your purchase decision.

HIARCS 13 UCI is a chess engine and is available by software download only. HIARCS 13 UCI requires a PC running MS Windows 98, ME, NT4, 2000, XP, Vista or Windows 7 (all versions 32 & 64 bit) with a UCI compatible GUI (a Graphical User Interface is not included in the package). We recommend the excellent free Arena GUI which supports UCI chess engines like HIARCS UCI.

Dedication

I would like to dedicate HIARCS 13 to my Nan, Lily Uniacke, who sadly died very recently. A strong, genuine independent lady who was as reliable as you could find, a true woman of substance. Her love touched and enriched my life even in her last years.
