are you saying that a .ctg book could have the centipawn metrics?

so i can do this with a collection of my games?!!?

The "Houdini" opening book is here. I don't know if it's really in stock. Plus it's quite old.

Check out the Hiarcs books, there are some older ones for free download, if you like what you see then you can consider their subscription.

The other good book is ChessBase's, a premium account gets you full access online. No saved evaluations, instead you can get live analysis from an engine on their server.

For use in Aquarium you want the Fritz PowerBook in .ctg format. Confusingly, searching for PowerBook from the ChessBase shop doesn't return this one in the list. Note that I haven't tested this in Aquarium. But you can download a free .ctg Hiarcs book and if that does what you need then you will know the Fritz PowerBook also works.

it is awesome.
