Suppose that I have no opening book {for example's sake} and I am analyzing the
root position for the start of the game:
[D]rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq -

Let's suppose that when it is time to move, I choose 1. e4 to get this:
[D]rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq -

Now, maybe the expected response is 1. .. e5, but other moves seem just about as
good.  So instead of choosing e5 and pondering this:
[D]rnbqkbnr/pppp1ppp/8/4p3/4P3/8/PPPP1PPP/RNBQKBNR w KQkq -

I ponder instead my current position:
[D]rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq -
because the response is very much up in the air.

On the other hand, if the opponent move is forced or an easy move, then I make
the move and ponder the response instead.  For instance, consider WAC.002:
[D]8/7p/5k2/5p2/p1p2P2/Pr1pPK2/1P1R3P/8 b - - acd 15; acn 32006264; acs 52; bm
Rxb2; ce 446; id "WAC.002"; pv Rxb2 Rxb2 c3 Rb6+ Ke7 Rc6 c2 Kg3 Kd7 Rc4 d2 Rxc2
d1=Q Rc5 Qe2 Rd5+ Ke6 Re5+ Kf6;

Here, I assume that the rook will be taken in response and analyze c3:
[D]8/7p/5k2/5p2/p4P2/P1ppPK2/1R5P/8 w - -

Or if the opponent move is forced, I ponder the response.
Or if the opponent move is obvious or takes most of the search time etc., I
ponder the response.
