Do you like the opening book by Jiri Dufek that's used with Rybka 4?  Does this opening book cover gambit lines? Thanks.

I read a few articles, and all I could find was one interview where Jiri Dufek says that his opening book covers the Queen's Gambit Accepted and the Ruy Lopez: Schleimann Defense, Jaenisch Gambit Accepted.

No one seems to be interested in chess engine opening books  - or owns this opening book. This thread has gotten no responses.

My question - does the opening book by Jiri Dufek/Rybka 4 have gambit lines? Can Rybka 4 evaluate gambit lines, or does it get confused with pawn sacrifices?
