Note about the UCI engines

Answer

Fritz was designed as a multi-engine system and allows - as does ChessBase by the way - the integration of various chess engines. The graphical user interface and the actual chess program are strictly separated from each other and communicate with each other via a predefined interface. A large number of chess engines are available for download via the Internet, which communicate with the user interface via UCI protocol. UCI stands for Universal Chess Interface and was developed by Stefan Meyer-Kahlen.

Fritz supports engines that work with the UCI protocol and you can integrate them under the Fritz GUI.

Under the menu item Engine - Create UCI Engine you start the dialog to integrate the UCI engine.

What does "Priority – Below normal" mean ?

This is about the distribution of the computing time. The communication between the program interface and the chess engine runs via a separate program, the engine interface. The interface runs with low priority to allow the parallel running chess engine a maximum of resources. Some UCI engines have problems with the default setting when the interface could not directly take over the ratings and other information due to lack of resources. With the setting " low priority" you can fix e.g. display problems of UCI Engines.

The actual UCI engine gets the appropriate computing time even with a low priority and brings full performance. So the setting has no negative effect on the performance of a UCI engine ! This can be easily determined by analyzing a given position with both settings on/off. The setting has practically no effect on the speed, it is about a smoother operation.
