hmm, i'm not so sure about that :-)
well, i know i shouldn't be lazy - but there is so much i would like to teach my
engine and that has priority over book stuff at the moment - i was hoping for a
quick fix to this. the reason is that when playing on ICC without book you get
drained immediately by people who enjoy playing the same game over and over
again... i know that i could report these guys, but i don't see the point. i've
made it play a half-random move on the first ply now, but that is not really a
solution.

i have implemented UCI indeed, but somehow the CB interface is unhappy with my
implementation and doesn't recognize my engine. it works fine in arena though. i
also thought it wasn't easy to play on ICC with CB interfaces?

i guess that is a personality thing. coming from checkers, i have a deep dislike
against books and endgame databases, because they have effectively destroyed
that game (with good book + large database you can have any crappy program and
be good, without you can have a great program and be bad). well, i guess i'll
just have to take your advice and write that PGN parser :-(
