hi dieter,
i never test with books (or never up to now). i'm not all that interested in a
book contest. i usually run nunn2 matches against crafty, gothmog and frenzee.
the nunn2 match has a wide variety of positions, and i like that a lot. i think
it gives a good impression of what an engine can do on it's own.
my current book is ok, but not deep enough (auto-generated from PGN, but only 19
ply). of course i'd like to have a deeper book, but since a friend of mine made
it for me, i can't really complain - i just have to hope he finds some time to
change that constant 20 in his program :-)
once i have a serious book, i'll use that for engine matches from time to time,
but currently the only use of it is variety for play on ICC.
as for bob complaining, there is no big danger, because whatever stupid settings
i apply for crafty, it will still easily crush muse...
cheers
martin
