Hi everybody.

I am making an opening book and want the engine to play various lines against me at the same frequency as humans play them.
I created an opening book from Chessbase and imported it into Aquarium, and want to globally change the play percentages to be the same as the total % shown in the picture.

I know how to do it manually one move at a time but it would take more than my remaining lifespan to do it that way.
Is there some way to edit the CTG or AQT file? A script maybe?

The widebook pretty much does it except you have to change the weight for cap and eval values to 0.
1. Make a copy of the widebook tree and give it another name.
2. change the weight values of this new tree as follows
a.  make sure it's a clean copy of the orginal widebook
b. set eval weight to 0
c. set Beval weight to 0
d. set cap weights to 0

The Play % column will reflect the relative percentage of games in the totals column. (It won't be too much different from the original Play% numbers)
The Play % numbers are close to tournament game percentages, but also reflects the editorial choices of the book author.
Once you set up your book, you can use choose a different reference tree for the totals column to suit your personal preferences.
