CHESS ENGINE INSTALLATION IN ARENA
(GUI = Graphical User Interface)
Follow the steps described below:
Copy the chess engine to a directory on your computer.
Open the Arena GUI.
As shown in picture below, click on ENGINE and then on New Engine.
You should see a small gray "UCI or Winboard" window.
Rybka is a UCI engine. UCI is the most popular computer chess language.
More precisely UCI is a protocol for communication between chess engine and chess GUI.
Every major chess GUI supports the UCI protocol.
You will see something similar to this picture:
Find the directory where you had copied the Rybka engine to.
Select the engine file (e.g. Rybka v2.2.w32.exe).
You are done with the installation.
You can start using the engine now. To do that, click on ANALYZE..
Enjoy your chess analysis!
