Yes this is won.
Kd6.
If Rxf8 then Ke7 and then the pawn goes up. K+Q against K+R is won.
if Rxb7 then
Be7. now Rb8 is forced then Kc7 and now the rook has to go somewhere on the 8. row.
if Ra8 then Kb7 and the Rh8 is the only option then Bxf6 and The game is over.
pall sig: But the line goes further: after Bxf6 in your line, rook moves to f8, then bishop to e7, rook only has h8 or e8. In either case king comes back to c7, rook keeps moving in the eighth to a8, then Bd8 is over
Yes. Kxpawn, Rxpawn, bishop shields pawn, king moves up to 8th rank, bishop shields king from check and pawn then queens.
In fact, there is a mistake: when Rf8 the pawn is lost. So, there must be another answer
further, if rh8, then Bf6 is check skewering the rook. So Kd7, rook checks on 6th rank, Ke8, rook checks, and Bishop interposes and pawn queens like I wrote earlier.
if the blk king was not on the long diagonal, Rh8 whenever Kd7 is played will result in a draw.
