Think about the _time_.  If your branching factor is 3.0, then would you
prefer to have one program's analysis after a 12 ply search, or three programs'
analysis after 11 ply searches?

How many times have you seen positions where one more ply was critical?

How would you compare (say) a X ply search by (say) Fritz, to an X-1 ply
search by Hiarcs, Shredder and Junior?  That is a difficult question and
I am pretty sure I would rather have the X ply search against another
computer.  Against humans?  Perhaps not.  But then I would also want a
_strong_ operator to choose between the three moves, not a computer program.
