Subject: Pondering ("think on opponent's time")

Which of these strategies for "think on opponent's time" makes more sense?

A) To only search the top-move from the principle variation.  If
the opponent makes that move, continue searching, otherwise reset and
search again.

B) To search all possible moves the opponent might make.  When the opponent
moves, reset and search again (but faster, since the hash tables have been
seeded).

C) Some other strategy?  For example, to use A) only if the top move is
'singular' (has a significantly better score).

What strategy does your chess engine use?  To date, I have been using "A",
but I am beginning to think that "B" or "C" might be better.
