You are looking at a different solution. This is for:

Originally posted by JonathanB of LondonWell remembered, rather. The proof is that your diagram is wrong - wPg2 is needed to keep Bf1 shut in [to prove that those squares aren't really g2 and f1!]
That is exactly the point that proves the solution.
Well detected!
Edit: And for some reason, the Smullyan diagram has bNf6 [c3, once proof is applied].
Originally posted by lauseyHa, wrong! Knight can't get to f6. However, Nc3# works.
Ahhh, sussed it out. Square a1 is at the top right, so white is playing down the board. Nf6# 🙂
Thought it was impossible at first as I went through every combination which does a check (with the board the usual way round, there aren't that many, just Nh6+, Nf6+ and Rh8+).

I had to change the diagram from when I first published it because I'd made a minor mistake elsewhere and obviously these errors crept into the corrected version - thanks for pointing this out.
I'll correct the blog now.
