What post? This one?
Well, I knew this Problem but from a different start position.. (BTW: the black pawn is in e3 not d3…. Humbly, the image is pretty bad).
To not spoil this one a lot I will only say white first move is:
1. Nh5+ ….
1. … – Kg6
then is the only move. (going to the 8th file will alloud d8=Q+ and Kf7 allouds queening in d8 too because ther is no more a fork in f7..
So white now …well …I know how it continues, let others try. ;^))
A.N.
why not 1.Bb3
Just checking — the FEN for this puzzle, including the correction in post #3, is:
8/3P2k1/n2K3p/2p3n1/1b3N2/2p1p1P1/8/3B4 w – – 0 1
… is that right?
if 1. Bb3 then 1. … – Ba5 controls d8 square.
Are we all stumped? (I know I am!) Not like this group to go twenty hours on a puzzle and not make any headway.
1.d8=N seems to be a good start.
1.d8=N seems to be a good start.
1. Nh5+! Kg6 {I think other moves lose very quickly}
2. Bc2+ {Forcing the Black King to take White Knight. If black king moves to f7 square, black knight cannot fork the White King and d8 square (pawn promotion to white queen)}
2. .. Kxh5
3. d8Q {Black King on h5 is almost cornered, so we force the knight away by queening, thus, isolating the black king}
3. .. Nf7+ {forced}
4. Ke6 {Bringing the white king closer to the black king for the kill}
4. .. Nxd8+
5. Kf5 ..
6. Bd1+ {and possible mate in a few more moves}
All that remains is to work out how White copes with 5…e2. (Your first five moves are right, as I’m sure you know.)

Solution:
Now, all that is required is for white bishop to give a check to black king from d1-h5 or e8-h5 diagonal.
So, if 5. .. e2 {to avoid Bd1#}, then:
6. Be4 {for possible mate by Bf3. If 6. Bd2, then .. e1Q and all hopes gone for white}
Now, things becomes more interesting:
6. .. e1N {instead of the usual e1Q (if e1Q, then Bf3#)}
Now, Bf3# not possible. So, try another square on d1-h5 diagonal. Possibly e2 or d1. May be we can also try for diagonal e8-h5.
7. Bd5 {can’t try e1-h5 diagonal as black knight is guarding c6 and f7 squares. So, now to try and place white bishop on e2 or d1 square}
7. .. c2 {seems like the best move to protect e2 square by c1N}
Amazingly the game has to continue on similar lines and the rest of the moves are:
{All white bishop moves are to the reach the checkmating square (diagonals e8-h5 or d1-h5}
8. Bc4 c1N
9. Bb5 Nc6 {all black knight moves are to block the bishop from moving on to the checkmating square}
10. Bxc6 Nc7
11. Ba4 Ne2
12. Bd1 {Finally, reached the diagonal}
12. .. Nf3 {I’ll block till I die}
13. Bxe2 Ne6
14. Bxf3# 1-0 {Bishop finally succeeds!}
