Bluffing.  Dictionary attacks count on a significant fraction
of users choosing passwords from a particular small subset of
the space.  Dictionary attacks then concentrate on that subset,
thus rendering themselves suboptimal.  And choosing passwords
to exclude dictionary attacks is counting on the attackers to
be suboptimal in that respect.  And around we go.

A perfect poker player can't be bluffed.  But neither is he
capable of bluffing.
