Ah yes, thank you.
Which just leaves the bishop to find a reason for ...
A reason for promoting to bishop is again to avoid a stalemate, that might happen with a promotion to a R or Q.
In the diagram below, promoting to Q or R is stalemate.
Instead, the fastest mate is 1.a8(B), Kf8 2.b8(Q or R), Kf7 3.Bd5#.
And if 2..Ke8 3.Ke6 mates and if 2..Kg8 3.Kg6 mates
