The 3-3 play isn't one I'm familiar with, and I've no idea how the above
would occur in a game. Why has neither side taken the 4-4 point instead
of one of the existing moves?

Anyway, I'll have a go:

with the rest depending *very* much on what the rest of the board looks
like; White is now building up thickness that makes me want to know what
it's facing.

In that case I would expect Black to be consistent: having failed to
respond to two out of the three existing White approaches, Black must
have valued other parts of the board more than expansion from this
corner. I expect Black will happily sacrifice the stone at 1 to get a
solid, smallish corner.

Again, this position doesn't seem reasonable in isolation. I wouldn't be
able to decide how to play without seeing what the White stones are
facing.

Where are the rest of Black's stones on the board? Again, the situation
looks very unnatural to me if Black has left this entire corner of the
board alone except that one stone.

I've given my reasons: the question is senseless to me without that
extra information.

> The board is empty, it's a life and death problem.

I'm not interested in life-and-death problems that don't resemble
positions that would arise in play.
