Chess960 under Arena

Chiron can play Chess960 both as UCI and Winboard engine. However to make Chiron play Chess960 games as UCI engine under the GUI Arena you should follow the following two steps:
1) after you install Chiron in Arena, write in the “Command Line Parameters” text box “gui=arena” (without the quotes)
2) before starting a Chess960 game, you have to check the UCI option “UCI_Chess960”
All this is needed because, unfortunately, Arena doesn’t follow the UCI Standard for Chess960.
