Knowledge isn't going to decrease your branching factor. Without some kind of
pruning you're not going to be able to get the low branching factor that they
get, right?

Maybe I misunderstand what a preprocessor does. As I understand it, it changes
how the engine evaluates the position based on what kind of position it is. So a
closed position might be evaluated differently than an open position, right?

Tiger may not use null-move to a high degree, but Christophe is on record as
saying that it does do pruning using his own methods. I'm just curious if Rebel
and Junior do pruning, or if it's possible to create that strong of an engine
without pruning.
