I believe the important thing is to add knowledge.
there are positions all the programs I know do not understand
in my nunn match I saw that fritz5, Junior4.6 and all the programs I
know
do not know to evaluate danger to the king and sometimes the programs
evaluate one side win for many moves when the result is the opposite
or draw.
in the 5th game both programs evaluated the position as more than
3 pawns for Junior(and a big part of the game as more than 2 pawns for
Junior)
 and the game was drawn!

other kind of important knowledge is what to search
and I see that programs are very weak in this knowledge.
for example no program I know discover that the position kasparov
resigned
against deeper blue is a draw.
an interesting question is what program is less weak than others
in the knowledge of what to search.
