>Junior5?

1)I think that Junior5 is slightly better than fritz5.

2)There are also other good programs that are not in the ssdf list for example
Rebel10, Chesstiger11.5(leading Shep's tournament) and chessmaster6000
We have not enough information to decide which program is number 1

3)I am not sure if Fritz5 was the strongest program(It was and is one of the
best programs)
Hiarcs and Nimzo98 are also strong and I am not sure if the first place of
fritz5
in the ssdf list is  justified.
2 reasons:
a)This list is based on long matches between programs and if the order of the
games was different maybe the results were different because fritz5 is good at
learning a specific opponent.

b)Fritz5 is optimized for the pentium200MMX that was used in the ssdf games so
if you have another machine then your results may be slightly different.

4)There is not a definite answer because the best program against program may be
different from the best program against humans and the best program for matches
may be different from the best program for tournaments.
