This is not really a transposition, as far as the opening book is concerned, because of the two different moves 3.Nc3 and 3.Nd2. The opening book does handle transpositions involving different move orders resulting in the same position. >2) >Do the book-import utility handle variations in pgn files? >This is fairly important when hand-making a book.

Is it this still true? >Not so important if it still point with line-number where it went wrong. I would imagine so, although I do not know for sure. I don't think anything specific changed here, so I would guess that the behavior is the same as it was with CM8000. jm
