I think it is meant that it is best to use a program with steady parameters.
It is not good to have different settings for different position types because
in a game you can't also change between the settings...one for all, that is the
message. It reminds me of CSTalBLACK and CSTalWHITE, in fact it is one program
but splitted into 2. Coming next is CST consisting of CSTwhite_e4, CSTwhite_d4
and CSTblack_e4, CSTblack_d4 and so on. Where does it lead us? Luckily this
behaviour was given up.
But it rests that e.g. Rebel's strongest settings don't find moves Rebel with
not strongest settings, e.g. combination=off, does find, depending on the
positions? Next step is finding best moves only with comb=chance and beep=on.
:-)
Also the King has some settings where he crushes all testsuites demanding sacs
but he PLAYS ugly.
