I think that no program of today should be called knowledge based.

I looked at the evaluation of hiarcs7 and chessmaster6000 in one game that they
drew.
Chessmaster had KBPP against KR but could not make a progress.
Both programs evaluated the position as a clear advantage for the KBPP.

It is clear to humans that the position is a draw not because of some static
evaluation function but because the pawns can do no progress.

A program that cannot understand thess simple things that humans understand is
not deserved to be called a knowledge based program.
