Unpack the download file to your Arena books location, i.e. ...\Arena\Books. Then, select it via the Arena book menu, and/or in the engine configurations as you wish.

The book focuses on openings which are frequently played. That's why some openings are missing. It shouldn't be a problem if used for testing only, whith all engines using the same book. The default book settings are intended to achieve a fairly useful book behaviour, and can of course be adjusted or optimized, according to your preferences.

Happy testing with the Balanced-14.abk! :-)
