Of course, every program can do this, but that's not what I wanted to know. What
I meant was which program plays the queens gambit without book, without weird
tuned piece square tables and without learning data (Ed, I think you use the
database information for tuning the piece square tables, too, or are you doing
some more sophisticated with it?), and - maybe this is the main point - _not_
because it can get back the pawn with Qa4+.

Greetings,
Steffen.
