Wouldn't it be great if somebody could post a definitive report on how book
learning is really supposed to work, and somehow compare a few programs'
learning features ?

For example Mchess has both book learning and "regular" learning... now what's
the difference, and does it really work as it's supposed to ? And where exactly
does a program's learning aftereffect actually kick in, i.e. at which point do
you discard a branch? In fritz5 book learning seems to gradually eliminate a lot
of the early replies until you're left with one move ( let's say 1.c4) which
then gets played over an over, unless you reset, which does, to an extent,
defeat the purpose of any real learning. This seems very crude. Hopefully
someone  can point to a more intelligent learning feature. I think it's a
fascinating subject.
