[Retros] At-home initial array challenge

[andrew buchanan]

Francois,

I have found a longer White-pristine at-home position (C+) which is now
published as H0006 at http://www.problemonline.com/. I conjecture that it is
the longest such. (Feel free to refute.)

So how far have you explored pristine at-home positions? I don't want to
stumble away searching for butterflies in regions of the rain-forest that
you have already bull-dozed. :-)

And I wonder if there any pristine at-home positions in which *both* of the
pristine knights have moved...

Cheers,
Andrew.
