I don't think your response is sufficient considering the question raised. There
are two ways of performing matches with book learning IMO. The first one is
indvidual books with the weights reset before and after the match. The second
one is a book for each engine that is _never_ reset. Even when switching
computers. The latter option can cause some problems with several different
matchmakers as in the case of the SSDF. The former option is virtually
foolproof. Which one do you use?
