  Hi Djordje,
   In addition to the interesting info in this thread, there are just a couple
of things I would like to add.
   In the case of search depth versus knowledge, you quite rightly pointed out
that search depth *is* knowledge. Since the basic problem of a chess programmer
is correct allocation of limited processing capacity, perhaps in the case of
Fruit2.1, the programmer has succeeded in his effort to include only vital, not
unnecessary knowledge, so that the released capacity has driven the search
another ply, or at least part of a ply. This applies to Shredder too, of course.
  I remember some time ago the author of Hiarcs saying that he had vastly
increased the knowledge in his new version. This could only have come at the
expense of search depth, and so was a mistake.
  Just one other point re: Fruit2.1. I could'nt help notice that Fruit2.1 has a
preference for knights over bishops. This I noticed over a series of too many
games played on Arena for it to be random. I'm only guessing, but could it be
that the knight, handled correctly, is a stronger piece overall than a bishop?
And that this has not been recognized in the chess community until now simply
because it has been impossible to search deep enough to demonstrate? Food for
thought.
  all the best
  Lin
