What I've taken to doing with opening books is that I use only games played
program vs program, although I do have a few GM vs program games left in there.
My idea being that passed the first few moves I have a good chance of still
finding some more moves allready calculated out by better programs on more
impressive computers, so I won't have the program doing searches quite as soon
because the work's allready been done.

I also don't use draws, long games (80 moves is too long), or short games. And
the whole collection is games played since 1995. I'm sure I'll use the games
currentlly being played at Paterborn.
