Genius3(p90) already scored good results at 25 minutes per game including 1.5-.5
against kasparov.
It lost 2-0 against anand but it also beated anaother GM 2-0

It happened against unprepared opponents and kasparov even complained after it
that he believed that he was playing Genius2(kasparov later beated genius3(p120)
1.5-.5 when Genius3 used a different opening book but it was only after some
preperation from kasparov.

I believe that Shredder4 on K6-450 is clearly better than Genius3 on P90
so I expect it to get more than 50% against the top GM's if they are not
prepared unless the top GM's play today significantly better than the level they
played in 1994
