Changing the Chess Engine
To change the chess engine, click on the Select Engine button.
The app will open a window where you can choose the engine to run.
For Windows you’ll be choosing from a list of .EXE files. The extension will probably not appear. Instead it will label the Type of file as Application.
Double click on the engine file you want to use.
The file name of the chosen chess engine appears at the bottom of the window.
The app will remember your choice of chess engine the next time you run it.
