I know only that Amir Ban assumed that it is not legal to use knowledge about
the opponent(otherwise he would change the contempt factor as a function of the
opponent)
The same for other programs like Genius3.

Junior does it only if you tell it to do it.
It is not a problem for Amir Ban to define a rule about the contempt value as a
function of the elo of the opponent
(for example contempt=5.13-ssdf rating*0.002).
