Wow...thanks!! I think you did not understood my message: CB books needs to have a great variety...they are required so... The tournament mode should be ON to avoid more weakening and not the other way around. They are made for ALL the chess players and therefore not playing only the best moves to keep variety. So if my book we are leading the SSDF list and with another book we could do even better than I better suggest Stefan to get a better book!:-) We made it on purpose to avoid Shredder taking off in the SSDF list!:-)) > >Shredder 7 and 8 both gained an immense amount of opening strength by using the >Deep Fritz book, which was the standard practice on the servers. > >>The only difference with UCI version is that the CB interface allows for 2 book >>settings while the UCI has 3. >>The CB tournament setting is like the UCI std. so allowing a wider range of >>moves to play. >>The tournament book setting in UCI allows only moves from a to c and not the d >>ones, if available, so only stronger moves and this can be estimated in about >>10-15 Elo points.
