Very impressive. Seems, Ktulu has a very good "static" (supported by search, of
course) evaluation of the resulting pawn endgame here. Do you have the patience,
to try for a bit longer?

I don't understand all of the output. 18 s for the first PV at depth 17,
followed by 0 s for depth 18?

Lack of more responses until now may indicate, that the position is really hard
for most engines.

Regards,
Dieter
