This book import allways crashes on my machine. It isn't necessarily Chessmaster's fuilt because the ref. dll with the exception is from a translator program (IFinger). I'm sure I sort this out but before I begin I have three quick question about the book-import utility. 1) Do the book handle transpositions? I did a quick test with adding manually one of the main line in Caro Kann: 1.e4 c6 2.d4 d5 3.Nc3 exd4 4.Nxe4 Nd7 Then I added the theoretical correct road: 1.e4 c6 2.d4 d5 3.Nd2 exd4 4.Nxe4 When I use this book and play as white the second line it would not find 4...Nd7 from the book. All bookmoves for black has three red dots. At the moment this is rather important because I practice a bit with Kramnik's method for d4 openings (1.Nf3). 2) Do the book-import utility handle variations in pgn files? This is fairly important when hand-making a book. 3) The CM8000 version needed a mate symbol (#) in the pgn-file if the ending was with mate. Is it this still true? Not so important if it still point with line-number where it went wrong. Odd Gunnar
