I want to encourage (as white for example) e5, when I have a pawn on d5.

If I give a bonus for having pawns on e5, d5, this only applies to the
node at which I play e5. Since it is rapidly exchanged in most lines -
the bonus doesn't apply in later evaluations.

How do I get a passing feature into the evaluation - or must I get real
sophisticated, identify position in which e5 is desirable, and then have
a flag to get me a bonus for having played it? Then I have to look in
the tree to see if I played it? Or maybe add to a positional bonus as
the move is made?

Any other approaches?
