Normally when you enter a move the program will start playing against you. You can also switch to infinite analysis, in which case the engine will calculate in the background while you enter moves for both sides.
If you want to turn the engine off altogether you can do so with " Switch off engine ". After this the engine will not run in the background, which is useful if you are running a number of program at the same time.
3.8.5 UCI Engines
What is UCI? This program was designed as a multi-engine system. This means that the graphical user interface and the actual chess engine( the module that calculates moves) are strictly separated. They use a pre-defined interface to communicate with each other.
UCI stands for Univ e rsal Che ss Int e rfac e. It is a communications standard defined by St e fan M e y e r-Kahle n. The UCI interface is closely related to the " Winboard " protocol. This means that existing Winboard engines can be very easily adapted by the authors to run under our interface. For these programmers the new UCI interface has the following advantages:
The engine can be run under an interface which has numerous advanced testing facilities that allow them to improve the strength of the engine.
The engine runs at full performance and strength without the need of additional adapters.
The engine will become available to a large number of users, who are able to install it without the need for complicated configuration, as is often the case with Winboard.
The UCI protocol may be used without any license fees, for private and for commercial purposes.
A UCI Engine is installed using the menu Engine s two purposes:
