Subject: Iterative Deepening

We all know that searching 1 ply, 2ply, 3ply, 4ply etc produces faster
results than just searching 4 ply by itself because the move odering
improves the efficiency of the alpha-beta pruning.

But ...

Has this approach ever been used above the base of the tree?  i.e. If
I am doing a seven ply search and I make the first move for white and
I am searching the black responses, at this point would it pay to do
a 1ply, 2ply, 3ply, 4ply, 5 ply, and finally a 6 ply search?

If so, then the number of sub-searches would get quite high.
