Also, I specifically bought Junior6, >because the opening book was prepared by GM Boris Alterman. I also thought that GM will do a better book and I see that I was wrong because when I look at Junior's games I see that Junior does not get a better position in most of the games against computers. I suspect that alterman did not work seriously for improving Junior's book and the only reason that they gave a GM to work for Junior's book is not to improve Junior's book but to tell customers that the book was prepared by a GM. It also seems that the book is based on games and there is no case when Junior plays a move that was not played in more than one game if you optimize book for playing and I think that it is a mistake. I read that in one of the games of Junior against zarkov one of the moves(Qxb2) was marked by ? but Junior did not find a move that was played in more than one game so it had to calculate and finally played the bad move Qxb2. I do not understand it because if alterman analyzed the relevant position and found that Qxb2 is bad then Junior should play the move that alterman believes that is best without caring about number of games.
