Sure, Crafty, Ruffian, Rebel can read a private book when no opening book is set
in the Fritz8 GUI. The ChessBase Hiarcs9 (Fritz, Junior...) does not have a
private book like these others. My point was that when your engine is intended
to work under Fritz GUI it needs to have special attention and not rely on the
engine doing blunder checks. BK
