{{Main|Chess engine}}
A "chess engine" is software that calculates and orders which moves are the strongest to play in a given position.  Engine authors focus on improving the play of their engines, often just importing the engine into a [[graphical user interface]] (GUI) developed by someone else.  Engines communicate with the GUI by standardized protocols such as the nowadays ubiquitous [[Universal Chess Interface]] developed by [[Stefan Meyer-Kahlen]] and Franz Huber. There are others, like the Chess Engine Communication Protocol developed by Tim Mann for [[GNU Chess]] and [[Winboard]]. [[Chessbase]] has its own proprietary protocol, and at one time Millennium 2000 had another protocol used for [[ChessGenius]].  Engines designed for one operating system and protocol may be ported to other OS's or protocols. Chess engines are regularly matched against each other at dedicated [[chess engine#Tournaments|chess engine tournaments]].
