  • The HIARCS chess engines included in the package are UCI compatible:
    • Deep HIARCS 15.0 (available with the Deep and Premium HIARCS Chess Explorer Pro products)
    • HIARCS 15.0
  • Opening books - these are collections of positions, moves and statistics which help show you the chess openings, play chess openings and classify and name openings played. These electronic books are used by HIARCS Chess Explorer to present the information within them. They cannot be read by other software.

Please note you can add other UCI chess engines including third party UCI chess engines into HIARCS Chess Explorer Pro. You can also use HIARCS chess engines in other chess GUIs which support UCI engines. We strongly recommend activation of our engines in HIARCS Chess Explorer as we have found many other chess GUIs are not 100% compatible with the UCI specification for activating/registering engines.

Premium HIARCS customers will receive the latest HIARCS experimental improvements, many of these will be aimed scaling on many core systems.

By default Deep HIARCS 15.0 uses half the physical cores of the system. We choose this default so that most customers are able to run Deep HIARCS 15 in multiple database tabs without affecting overall system performance. You can change the number of threads used in the Analysis Explorer toolbar. That allows you to set anything from 1 to a maximum of the number of logical cores on your machine. If you want to change the default threads used for Deep HIARCS 15.0 in all database tabs please go to the Preferences->Engines dialog and select Deep HIARCS 15.0 and set the threads to your choice.

Please note HIARCS Chess Explorer Pro also has a load alert which is a red square which appears in the bottom right hand corner of the window, if you see that you can move the mouse pointer over the red square to get info on the system usage of the engines running.
