Effect of "Own Book" vs Generic book

[hirdelgird]

yes I also think so, in the german paper print of "Computerschach & Spiele" in year 2002 or 2003 there was a check about books with Junior ? - result was that around 1000 games it doesnt matter if use own or general book

but now this paper magazin is dead its followed by an also payable online newspaper http://www.computerschach.de/
have looked at but these arcticle seems not to be published on webside

Isn't this already done? I remember to have seen a test, either here or on the Winboard forum, where 6 top engines with book and the same 6 top engines without book played a round-robin with a large number of games.

Following on a discussion in another thread - there seems to be quite a bit of interest in what an engine can gain by using it's own book, instead of the generic books used by all engines as in CEGT and CCRL

I think there was a number of tests played with results in this
forum 2 or 3 years ago. That was test with books and without
books i think.
I don't know if there were test made with own book vs.generic bk.

Hi Ray.
I advice you using also bizarre books. For search gaps. I use
odd and gambit books:

For Spike
SpikeOddBook.scb
SpikeGambitBook.scb
SpikeFrenchBook.scb
SpikeD00-D09Book.scb

Binary (for Fruit, Toga, Glaurung 2 ...)
ph-gambitbook
ph-exoticbook
ph-variedbook

E.g.: I use
2x Shredder (own and gambit.ctg for Shredder Gambit)
4x Fruit or Toga (exotic, gambit, varied and tournament book)
etc.

Best wishes P.H.

On the other hand a weak engine using a strong book would only avoid problems it can't see on its own during the opening. In the middlegame the weak engine's good position it got from using a strong book would begin to deteriorate and it would probably lose the game to the stronger engine anyway (only taking longer to lose) with little overall change in the result of the match against the stronger engine.

If I proceed with these tests, I would use HS-10moves.ctg as the generic book for all engines
