Are you sure this is the correct solution? The move that made the least sense to me was the underpromotion to a rook. A queen seems superior because black's king is not confined to the square it is currently on, therefore there is no potential stalemate danger for white.
Am I missing anything?

if 5. b8=Q, then 5....Bf1, then Qb1, king can go Kxh2. It will be a draw whereas if white go Qxf1, it is stalemate. This is also proved to be true if you go Qh7+ Black will go Bh3 to block. But, if you 5. b8=R Bf1 6. Rb1 there is no stalemate if black go Kxh2 then Rxf1. so black must go Kg2 to defend the bishop while also attacking the f2 pawn

It's the kind of position that gives some chess engines trouble. The queen promotion gives White such a high positive evaluation that the engine assumes there's a win just over the horizon.

yeah, Stockfish and Komodo 9 failed to solve it because they thought b8=Q is the best move

another puzzle, quite hard. White to move and win

Got every move (and very quickly) except for the last one (the win is elementary at that point). We had a similar daily puzzle with a similar theme recently so I recognized the winning procedure right away. But if one hasn't seen anything similar before this would definitely be a hard one.
