But if you actually mean matches where both engines use the *same* book anyway, I don't understand what you mean at all. Isn't it an improvement in this case, which greatly *reduces* distortions of a match result by book randomness, IOW if one engine would be "luckier" when it's openings are chosen? From a given opening book, AFAIK it isn't engine-dependant which moves are chosen, in Fritz. I don't see any bias for the first game's White, becauso no matter if he wins or looses, Black gets to play the same line in game 2 where he will be White. My question: But I noticed something else (in Hiarcs 7.32): In the setup dialogue for an engine match, book options are always offered for every engine each. - But this is book dependant; you cannot choose different book options for the engines when using the same book in H732. This isn't obvious (I know this is not what you meant, just an observation). In Fritz 7, I see that different book option settings are kept even when you set the same book - but when the openings are repeated, different book options of engine 2 will never come into effect for white... (?) In other words, the different book options would in that case NOT come to effect for engine 1 and engine 2, but engine 1's for white, and engine 2's for black always. Except I didn't get the logic right. Maybe people which are doing many engine matches, can acknowledge or refute that? Regards, M.Scheidl
