ChessBase started with Fritz, Junior, Hiarcs and Nimzo.
Hiarcs was the strongest.

Exactly. 4x nothing = nothing.

you have not seen the score of each position, don't you ?
I was there. I have it on video. draw-score , draw-score, draw-score.
As if chess is draw ! :-))

Aha. the draw scores are realistic !! :-)))
if a program only evaluates draw over draw-score, and loses (like fritz in paris
against ferret e.g.) what is the realistic part of the score ??
Ferret was 0.43 up and fritz was 0.00 ! What was realistic of this evaluation?
What was fritz evaluating ? Its chances to win the championship?

oh - what a pity :-))) the poor poor fritz.
