I'm glad to present you the "Fauzi 2.6.ctg" version for Fritz and Chessbase, together with the "Fauzi 6.9.abk" version for Arena.
For whoever as I am a chess lover which do not have problems in using more than one chess GUI, I have created also a special bundle product to be able to buy both the books together at a better price than buying each one separately.
However please note that the style and the lines played by the two books are completely different since they were created in different methods.
1) Ctg book contains more than 10,000,000 high-quality engines games, while the abk book contains "only" around 1,000,000 high-quality engines games due to the limits of sizes allowed by Arena for its opening books.
2) Abk book is more well-tuned using the priority of moves in nearly all the opening lines, while the ctg is tuned a little less and this is because Arena is more friendly user than Fritz or Chessbase when it comes to tuning manually each line.
Whatever opening book you will use enjoy your free wins :)
Using a combination of both the opening books has personally shown its potential and its strength in my correspondence games, as well as my testers.
Since I started playing Correspondence chess, using Fauzi.ctg book in conjunction with Fauzi.abk book, I was able to win most of my games and draw the rest due to the advantage obtained in the opening phase, and managed to never lose any single game regardless if playing with White or Black.
Here in IECC you can see an example: http://www.chess-iecc.com/show_ratings.php?min=2000&max=3900
Where I was able to win 52 games, draw 19 and lose 1.
I'm currently playing also some ICCF tournaments achieving similar results:
