user11144: Consider the following well-known motif:
[FEN "8/1k6/5pp1/7p/7P/6P1/8/7K b - - 0 1"]

Black wins even with Ka8, but being true Patzer:
1...g5?? 2.g4! Kmoch's crosslever, 1-0.
Now in the critical position after 1...g5, pawns are hanging. Can you conceive a position with the following conditions:

White, a pawn down, to move wins by a breakthrough
Everything beyond a pawn-free file isn't counted in "pawn down"
No free White pawns
If a White pawn has passed a Black one, the latter isn't counted for "pawn down" either
Black doubled pawns are OK
No captures possible in the position
Kings far away, play no role

(Note: After thinking ten seconds, I know the answer, but I still leave it as a puzzle for you. Feel free to think about how many pawns White can be down for a sufficient breakthrough.)

user32606: The g6-break comes to mind, as in
[fen "8/5ppp/8/5PPP/8/8/8/8 w - - 1 0"]

1.g6 hxg6 2.f6 gxf6 3.h6

We can adapt this. Here, White wins starting with the break 1.g6
[fen "8/pppppppp/8/4PPPP/8/8/8/k1K5 w - - 0 1"]

1.g6 hxg6 2.f6 exf6 3.exf6 gxf6 4.h6

Same idea in the center, now five pawns are needed, but we get a minority attack on either side.
[fen "8/pppppppp/8/2PPPPP1/8/8/8/k1K5 w - - 0 1"]

1.e6

This breaks works on fifth row as well, given Black can neither check (wK on c3) nor escort his own pawn in due time (wK on c1).
