By the way .. in this position it isn't so easy to get the knight to f6 .. (the
Bishop goes to f5 and the k to e7 and it is really hard to penetrate from there.
One problem with programs dealing with this, is that the bishop has a *wide*
open diagonal .. so therefore it might think it to be active instead of bad.
