White to mate in 3 (Eugene Cook)Well, we can rule out 1. e8(Q) as it is stalemate.
We can rule out 1. f8(Q) and the king runs away to c6 and White needs 3 more moves to mate.
I tried underpromoting with knights but that didn't lead anywhere quick enough.
I think the key is keeping the king out of c6.
1. e8(B) Ke6 2.Ke4 (to keep the K from running to f5) Kd6 3. f1(Q) and mate in a total of 4
1. e8(B) Ke6 2.f8(Q) stalemate
1. e8(B) Ke6 2.f8(B) (avoids stalemate, but keeps the K out of d6) Kf5 3. Bd7 mate
(ha, we didn't have to fear the king going to f5)
