Here is what I remember about CSTal 2.03.  The strength is changed by somehow
reducing the NPS searched.  On my XP2400+  it searches around 50K/Nps with the
setting at 50 (max).  At a setting of 1 it drops to about 500 Nps.  I tested it
on ICC several years ago at the settings of 1 and 2 mixed.  It carried a blitz
rating of over 2000 on the lowest settings.  While that is remarkable for 500
Nps search speed I believe many people playing it were simply intimidated by
playing a computer.  I still find it's playing style interesting and fun.

This I'm not sure of.  I've never tested it for learning.  I can find no file in
the directory that would indicate it has any learning feature.  However it could
possibly he hidden from me.  I did not make a big effort to check it.

Don't know.  I have the original CSTal CD (plus the 2.03 update file).
