It just depends on what one is interested in, it might be that the user/tester has a broader taste in openings and wants to see how the engines do given those circumstances. Of course you can make your engine play e4 constantly to get a higher rating if that's all it knows how to play well, but personally I don't understand why that would be interesting from neither a development or user point of view. In the long run I think it is actually a bit damaging for the development to impose this kind of restriction. >>Suppose a Correspondence player play a game and start from the opening book of >>engine A Now comes engine B and C that are better than A and D that is slightly >>weaker than A but is considered to have bad book and people claim that it is >>weaker than A,B,C because of having bad book. >> >>The player need to decide if to continue to use A or to go to B or C or D. >> >>In that case it is logical to do a turnament between A and B and C and D when >>all Use A's opening book. > >To the man who has a hammer, everything looks like a nail. > >Would you ask a player that specializes in d4 openings to give you advice on a >king's gambit line? > >I wouldn't... Hence the need to subject the engines to all kinds of different positions to see which one is the strongest "on average". -S.
