Hi Henrik, I sometimes use a book that is automatically constructed from a large collection of games. It just contains frequently played lines with symmetries removed, nothing fancy. IIRC it does not make the program significantly stronger, but not weaker either and it saves some time in the opening. I also have code for automatically generating an opening book, but I never tried that for 19x19 (and for 9x9 I'm not too happy about it either because, to make it really strong, it still requires some final human inspection, which I don't have the time for).
Without a book Steenvreter usually still plays decent opening moves because it is pretty good at predicting pro moves (predictions are used to set priors in the tree). However, with longer thinking times there is sometimes a tendency for its style to become more cosmic (not sure if that is good or bad).
