Very funny again, dear Hobacle, but this time I'm aware (21st, not 1st of April ), so it's much easier as for this one main point for humans (awareness), and of course getting approval from engines much easier makes one much more sure much sooner too.

I find the question more important than the one in my title is whether there's a puzzle SF MOJO cannot solve...

Sorry, but as I wrote, output comes with full hash after fome Forward- Backward, DTM wouldn't have arisen soon (maybe not even a proving output- line at all) otherwise probably, didn't wait long enough to find out.
But anyhow this one's much easier for engines than April 1st's one, much less unforced lines and Zugzwang- maneuvres much less deep (plies away from knot- positions).
BTW, did you publicise this one or April 1st's one already in any journal or competition?

Even if I'm not a judge, at least first one's might have good chances for a good award regards

I'm not sure whether plenty of people can understand me.

You're right, a second one black Pawn can't have come to f4 legally.

Anyhow, it's some easier even as your second one from today, not for engines, but for humans, at least for those who saw some of O.Blathy's other great puzzles before regards

It is legal, but too hard to solve for any engine that is NOT programmed with the triangulation method of wasting waiting moves

NO! NO! NO! What I wanted to say is not about the f4 pawn. a-d b-d d-f

But the two black rooks!!!

O.B. couldn't be so careless. The h4 pawn must be in h5 in the original position but someone stupid moved it later.
