If this is set to Yes, the server will attempt to bear off one piece per rolled number automatically. This is equivalent to issuing the 'off' command after every roll (if possible).

This feature is not meant to be used by beginners. Make sure that you set this toggle to YES in non contact positions only, otherwise FIBS will automatically make moves for you that you certainly don't like. If you don't know what a (non) contact position is: this feature is not for you!
