You mean S5dx6e, right? Mate enough, but leaves Black with an N in hand.

Actually, the one I came up with when trying to solve it was
G'4g Sx4g G'5g Nx5g S4hx5g which is mate (I hope) but leaves Black with a N=
 in=20
hand as well.

The only "clean" solution is the given one since it leaves Black empty-hand=
ed,=20
but I still think the tsume is flakey because there are alternative=20
possibilities to win for Black. Adding a G on 3f might fix it.
