Doesn't it depend on the definition of "ply"?  IE what is Junior's
branching factor?  How far does it jump between iterations?  (hint:
three).

I don't claim to know all about deep blue.  After reading the stuff in
the latest paper about how they did extensions, I wouldn't beging to try
to understand their numbers.

however, I have seen programs jump by 2 with what I would call "real plies"
and their branching factor was not 25 as you might expect.  Bebe was the
first but there were others...
