D) Undermining
By undermining, we mean that the head of the
pawn-chain can be separated from the rest. Say.
for example, White has a f3-g4-h5 pawn-chain
and can be forced to play gxf5, leaving the h5-
pawn loose. Of course, outposts can also be undermined:

Undermining can sometimes also take place
even if it is not absolutely desirable in the structural
sense, yet one's own pieces gain new targets
thereby.
