Hardly the same thing, as is surely at least as obvious. This still leaves
the perpetually unanswered question of how minute a bridge movement is no
movement at all. I had presumed that your post immediately following this
one would clear that up for me and put this increasingly tedious exercise
to rest, but it hasn't happened. I would like an answer to this please,
since it is the basis of your stand in this discussion.
