Just glancing, but it seems maybe 1.bf3 kc6 2.nd3, but that seems way too easy...

For me it doesn't appear trivial at all, but I do agree with your (Moshe lobel) first moves.
I was a bit worried about 2. ..., Kd6 3. Nf7†, Ke6 4. Nf4†, Kf5 as after 5. Nxd5, c2 it's a draw: 6. Ne3†, Kf4 or 6. Nd6†, Kg5 7. Ne4†, Kh4 = etc.
It turns out, that after 5. Bxd5, Kxf4 6. Bb3, Ke3 7. Ne5! White catches the pawn in all variations.

So the main line must be:
2. ..., c2 3. Nf7!, c1Q 4. Nxc1, Kc5 5. Nb3†, Kc4 6. Kh8!! and the King cannot keep the rook covered, while the rook itself is dominated despite having complete freedom of movement. Note that after other White King moves, Black can pin the Nf7 by either Rd7 or Rf5.

I just love these weekly endgame studies. #135 sub variation is incorrect (I think). 5. Kc8 is equal. because 5...Qxa6 6. Rxa5 wins. Therefore, 5. Kc8 Black must keep checking.
