Takes SF 64 plies to find this mate in 10. About four and a half minutes with 11 threads.
Of course, due to SMP variance, I would expect other solution times to differ a lot.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I do have one custom tweak:
If the number of possible moves is severely restricted I reduce null move pruning.
This is the version that I am using:

I also have contempt turned all the way off, though I doubt that changes much.

I think that it is obvious that 1.Nb6 is better than c5 even without seeing the mate.
Reason is the following reason.
1.c5 is a stalemate.
1.Nb6 axb6 a7 b5 Kxb5 is also a stalemate and because black has no choice it means that 1.Nb6 is draw or win for white.
It is obvious that draw or win for white is better than a draw so it is obvious that 1.Nb6 is better than 1.c5 even without seeing the mate.

I think that it is obvious that 1.Nb6 is better than c5 even without seeing the mate.
Reason is the following reason.
1.c5 is a stalemate.
1.Nb6 axb6 a7 b5 Kxb5 is also a stalemate and because black has no choice it means that 1.Nb6 is draw or win for white.
It is obvious that draw or win for white is better than a draw so it is obvious that 1.Nb6 is better than 1.c5 even without seeing the mate.
That is why I still like Rb4 for WAC.230, even though it is almost certainly a draw.
Rb4 either wins or draws. All other moves draw or lose.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Great position, Dann!
Although Zander finds it after almost 3 minutes at depth 49, 1 Thread, 512 MB Hash,
this is nothing to brag about.

What is really worrying is that ALL pv lines from depth 2 till depth 49 look like the following:

ahhh.. that makes more sense.. without null move pruning it just cant solve it.
Does'n it have nullmove verification search anymore?

That's a quantitative matter, and it isn't about nullmove only, the Bishop- underpromotion must not be pruned away neither.
CorChess solves this quickly, Sting too (it's in Marek Kwiatkowski's IQ- collection too) that might be because of more nm verification or of less nm pruning or of less other reductions maybe too. And of course more or less find mate code and king's safety parameter quantitatively helps too probably.
At least SF MateFinder doesn't have to ponder much here neither, could be because of less nm- usage too of course.

Takes SF 64 plies to find this mate in 10. About four and a half minutes with 11 threads.
Of course, due to SMP variance, I would expect other solution times to differ a lot.
