     Why not also in the DOS version?

     About the Windows version that will come later, do you expect
     some loss in the search speed? (I suppose we can expect that
     version to be a few percent slower...) Also, will there be
     significant differences between the two versions in what they
     offer?

    When I first tried changing the style of play (from Agressive
    to Defensive, for exemple), I was expecting great differences,
    like open positions with Agressive and much more closed ones
    from Defensive. However, if you effectively designed the various
    styles so that the ELO strengh does not vary too much and only
    the mobility terms are affected, then the changes are probably
    too subtle to be seen by only playing about a dozen games, as I did.
    I will have to test that further...

    It would be fun if the styles of play could be chosen
    along with the ELO setting option. I am not sure it's possible
    in version 9. If effectively not, could that be done in version 10?

     I hope the changes are to your liking. A child often grows
in ways least expected by its parents... :-)
