Hello Kurt,

Of course it is not necessary to tell you that it is not possible to give
minor pieces scores like 95/96 in the CM9-GUI.
My idea was:
- to give all own material parameters (except the pawns)
  a slightly higher value.
- to reduce all material parameters considerable
- to reduce the value of pawns relative to the pieces (IMO default Chessmaster
slightly overestimates pawns in the middle game)
- to give a bishop a slightly higher score than a knight.

The positional scores were initially the CM-SKR scores and I changed them a bit
because I saw some weaknesses in practical play.
I havnt tested it thoroughly of course and there is a lot room for improvements.

This CM personality should come close:

CM9 Misha.SKR

A/D  (Attack/Defender)    [  5]     M/P  (Material/Position)  [   0]
S/P  (Strength of Play)   [ 100]    C/C  (Control of Center)  [ 110/120]
Rand (Randomness)         [   0]    MOB  (Mobility)           [ 110/115]
MSD  (Max Search Depth)   [  99]    K/S  (King Safety)        [ 145/140]
SS   (Selective Search)   [  12]    P/P  (Passed Pawns)       [ 100/105]
C/D  (Contempt for Draw)  [   0]    P/W  (Pawn Weakness)      [ 100/100]

OWN               OPPONENT
Queen   [ 8.7]    Queen   [ 8.6]
Rook    [ 4.8]    Rook    [ 4.8]
Bishop  [ 3.0]    Bishop  [ 2.9]
Knight  [ 2.9]    Knight  [ 2.9]
Pawn    [ 0.9]    Pawn    [ 0.9]

Inbetween logfile:
