Fritz 21 Handbook

Advanced

Example

Engine parameters: click to set the engine parameter available for the selected engine.

Use Book/Use Livebook : Active those Databases for the access.

Hash table size: This is important if you are looking for optimum strength, especially in longer time control.

Tablebases are special endgame databases which allow the program to play five-piece endings perfectly (even find them in the search).

Smart CPU usage

On a computer with hyperthreading (i7 4 cores + 4 hyperthreading) a deep engine only starts with 4 threads/processes. On a computer without hyperthreading (i5, AMD) it starts with n-1 threads/processes. If you turn this option off it starts as in the older version.

Exception: The user has explicitly defined the number of threads/processes, for instance by defining a UCI engine.
