I remember the claim that Shredder is 100 elo better than Fritz6a when one of the reason is better opening book that is optimized for long time control games. What happened to this claim(remember that the time control of Enrique is similiar to the ssdf games when you consider the fact that Enrique's hardwrae is faster)? I think that you should tell the customers some monthes ago that you did a compromise in order to make the program fun to play with. I believe that a lot of customers do not use chess programs to play against them so making the program fun to play with is simply irrelevant for them because they prefer an opening book that help the program to win more games.
