Engines
The chess playing part of this program is separate from, and independent of the graphical interface. The playing part is called the "chess engine". The engine can be changed (Menu Tools – Engine), and the interface can support more than one engine at a time.
You can stage engine matches and engine tournaments.
ChessBase regularly publishes new engines, keeping you completely up-to-date with the strongest chess playing software in the world.
