no  the 3100 also uses 206 mhz ARM - for both Fritz and Genius did you use
analysis mode or did you set position and press go.  When I programs, I
generally don't use analysis mode I have noticed that occasionally program give
different results with analysis and play modes.  I will double check Pocket
Fritz - was there ever an update - I got a very early verson directly from
Germany - but that's a big difference.  I use a Palm Vx OS 3.52 that is
overclocked to 28 Mhz with - I would have thought you do better.
