A good book is not a book that leads you to better positions but a book that lead you to better result. I read that the 1.e4 c6 2.d4 d5 3.f3 line shredder has more than 90% result and if it is the case this line was a very good line. I read that the line against Sos was also good. I do not say that book of shredder was the best but I disagree that it was one of the worst >alex´book was BY FAR the best and there is NO doubt about that. >having killer line´s but also with hardly a whole. > >>>Which program had the worst opening book? > >here you can say shredder. > >>>Which program had the best middlegame?

Fritz could get nothing in the middle game against Junior so I prefer Junior(london) in the middle game. >>>Which program had the worst middlegame? >>>Which program was the best in the endgame?

It is not clear. Junior was the most interesting program in the event. I think that this program did the biggest change relative to previous versions. Sometimes the change was good(see the games against Rebel and tiger) Sometimes the change caused trouble when Junior played h5 against shredder or let nimzo to win it by sacrificing the exchange. I know that Rebel is a preprocessor so I doubt if it has the best evaluation. I do not like preprocessors for analysis. I may analyze a position when the computer say that white have an advantage when after castling the computer suddenly say that black has an advantage when it cannot see deeper. I know that not all the programs behave like this. Amir admitted that there are cases when Junior is a preprocessor but Amir hope to get rid of it. I also read that Fritz also behave better about this(I read that Fritz does hardly evaluations in the root). I know also from my experience that chessmaster is not a preprocessor. > >with a reasonable book i predict tiger to overrun shredder. You forget the fact that shredder can also improve the book. <snipped> >maybe shredder is now 10 points above tiger and shredder and fritz. I understand that you mean above tiger,Rebel and Fritz. The standard error is clearly bigger than 10 elo(even if you have some hundreds of tournament time control games) so if you say maybe 10 elo better it can be 40 elo better and can be 20 elo worse.
