I do not understand what is the idea of having a small and unsound book. The only logical idea of having a small book is in cases that the book is sound and every move in the book was checked manually or analyzed by the computer. I think that there should be 2 kind of books that it may be logical to use: 1)small and sound book when every move in the book was checked manually or analyzed by chess programs in the past. 2)big (and sometimes unsound) book like fritz powerbook. My guess is that this book may give advantage in blitz because saving time is more important in blitz but may cause problem at long time control because having sound lines is more important at long time control when the sides do less mistakes after book.
