I like to add, that I have only interpreted, or quoted more or less (in my own
words), the ideas Jeff Lischer expressed in the first posting of this thread
above.

It seems to me that one conclusion of the discussion so far is, that a
programmer will most likely want to apply the very same algorithm (which is the
one he works on, improves constantly and is the one and only he trusts most) in
each case, disregarding if the program has the move or ponders.

But we have an example of an obviously very strong and successful program, which
exists in two versions: Chess Tiger and Gambit Tiger. Maybe this can lead to an
illustration of what Jeff may have meant probably: Assuming a programmer fears,
a certain experimental, but promising version of his program might be too risky
to use alone. In this case, he could have the more "conservative" algorithms do
the search when the program has the move, while during the opponent's thinking
time, the gambit version fills the hash tables with evaluations of positions and
variations which occur from a different approach (which the standard algorithms
then make use of, when it's the programs turn to move again).

In other words, a kind of "Pinky and Brain" method.
