Fritz5 found b5 after 32 minutes and 43 seconds in my computer
pentium200Mh when it used 99,968 Kbytes hash tables
the depth is 14 brute force and 43 selective

Junior4.6 could not find this move in one hour.

Fritz5 found 22.g4 after less than 5 minutes
(I do not remember the exact time)
It evaluated the position as adventage for black and this prove
that fritz5 is good at finding good positional moves when the king's
opponent
is in danger(even if it is bad at evaluating)

I do not like the fact fritz5 is a good program but I cannot ignore
facts.
They do not deserve to be a good program because they want to be
number 1 by unfair means.
