Am reluctant to blurt it out. My many enemies and detractors are
absolutely dying to know.

So, send me an email so I can reply, subject it "Missing King"
without quotes and I will be happy to give you a position and
indicate the falling off point and perhaps a short note or two.
Actually, I better get out my board and work it out again, it is
not obvious! Been ages since I solved it. I made an animated gif
of my solution once to show it in action. For the life of me, I
do not know where it might be. Probably on a CD or old HD,
hundreds of which are lying about the place.
