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

Does White have mate in 26 or 28? This is from an actual game between GM carlsen vs Maxim Malakov Tata Steel 2018

Did you realize SF Mojo's output was MultiPV=40?
As a matter of fact 44 out of 53 possible first moves mate in 8, at least Gustav says so after 55,43 seconds regards

i feel not good to write this because its not a bit better than most of the replys given here.....i feel ashamed by the ignorance that Hobacle is given here...if i open a thread where i ask about where to call the best burgers and all i can read is about cars and prizes then i feel trolled...Hobacle asks for similar compositions as the one he gave us and not a single relevant comment has been given to him...this is not the respect he deserves...and @chessqueen: u really anoy me currently, u really annoy me man, u post not only crap in your own threats but the really bad thing is u pollute more than any other person threads of other honest people and that makes me feel sad...u really insist in your goddamn wrong solution given above by claiming a mate in 7 where such a mate does NOT exist (there are 44 different mate in 8 instead) and want to tell how clever U are and stupid the engines on the other hand...half an hour later u open a thead by yourself and tell us how good the engines are...your intellectual consistancy tends to ZERO imho but the worst of all is that u pollute threads as nobody else here and i think Hobacle deserves better answers when he ask for sth special
im sorry Hobacle to be offtopic, i hope that you will stay with us, i really hope that you appologize this bull....best wishes commerade
sincerly, Peer

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.
