No, the Queen on f1 covers b5.
Fun, although the key move wasn't hard to figure out. I liked the underpromotion though.
Well, its not that white has many moves to chose from.

I don't get why some people think if they fluke the 1st move of a puzzle they have actually figured it out correctly. In order to say you solved the 1st move correctly you must have visualized all the way to the end.
this is a very good and significant puzze. although it would be better if you can add more pieces to make it seem like a real position.

I'm a little confused about the context of your post, but to give my own two cents, I find puzzles with a non-intuitive first move more fun. After all, if the first move to the puzzle is obvious, it tends to greatly facilitate analysis of the subsequent steps; whereas if the first move is non-intuitive you have to spend much longer analyzing other possibilities resulting from other first moves.
For example, in this puzzle it seemed very natural to try to lock down all of black's moves so he had no choice but to push the f-pawn. Following that thought, it's not hard to see that pushing the b-pawn seals up all the pawns around black's king. So despite not having seen the puzzle all the way through to the end, the first move could be easily figured out, making the puzzle easier to solve (and hence less fun) than a puzzle where even the first move is hard to work out. I mean, if the puzzle had some other subtlety such that the "obvious move" of pushing the b-pawn doesn't work, then the time I spent analyzing that move would be futile and the puzzle would take longer to solve.

Wrong. This isn't the sort of puzzle that can be solved solely by logic. Tying down his King's resources was obvious as a pattern to consider, however if White's pawn was even one square behind on the race to promotion the win would not be possible. If the 1st move was found by any other method than calculating the win all the way to the end it was a complete fluke.
Could have promoted to queen or night instead

No, Black's Queen is covering b5 so only a Knight works.

Well, I think it is obvious that nothing else can work. In fact, it wasn't given that White was supposed to win; seeing that exf5 is stalemate and that nothing else is going to keep black's king locked up (and that therefore everything else is bound to lose) should be enough to choose the first moves. Only when the decision between exf5 and e5 arrives is it necessary to calculate the win all the way.

Yes, but still, thinking you've actually solved a puzzle just because it's the only move that can win when in an actual game it would have to be calculated to the end is not properly solving it. More like solving it without having a clue what's actually going on.
One thing about puzzles here is that when you make good move it you get OK msg, and you can continue the line. If I posted this puzzle as a diagram, does first move still look natural? If there is not that kind of help, you would have to play to the end of all variations to see where you end up.

True.
