Subject: How to know which move the Rybka book would play?

I've always used infinite mode for analysis. I've never used any other time
control. And when it comes to books, I just look at their data in the window
pane and make my best judgement, all things considered.

Now enters a book where I would like to know which move it would play
automatically (the new Rybka book) and I feel lost. I've never tried to
determine that before. Infinite mode won't work for this.

I set up everything per instructions in the readme file, but still I don't see
how to get it to make the book move so I can see it. Of course I'm using the
Chessbase/Fritz GUI (from Shredder 8). The best notion I have come up with is to
set the time control for a "fixed time".

So I load a correspondence game in progress that's still in the opening phase
and try to determine what move the Rybka book would play here. I presume that
when it starts thinking, it will play book moves immediately, which is how I can
determine that it's a book move.

But how do I get the engine to start thinking in "fixed time" mode for a
particular position? Or maybe there's a better way to do this?

I know you're gonna say to read the % column and look at the color of the moves
(green or red). OK, but that's not the same as seeing the move made on the
chessboard. I want to see it in action! :)

Also, I came across one instance where I'm puzzled. There were only 2 sample
games for the move that was played versus many sample games for the alternate,
both green colored moves, but it played the former. I thought at least 3 sample
games was necessary for it to play a book move?!
