This comment seems to indicate, that there really is a mate in 13. I don't
believe so - black will not recapture with the K. If black's first moves were
forced, I believe today's chess engines would find the mate from the root in
reasonable time - because of search extensions at much lower depth than 24. All
longer analysis shown in this threat don't have 1...KxN anymore in there line,
because the engines see the desaster after longer time and prefer to lose
material and keep the king for a while :-)

Yace shows (accidently) for a short time the "intended" line.
