| White to play and mate in four
}}
This 1912 problem by [[Wolfgang Pauly]] is, as it were, a three-quarter Babson task: three of Black's promotions are matched by White.

The key is 1.b3, after which there are the following lines:

{{unordered list|style=list-style-position:inside
|1...a1{{=}}Q 2.f8{{=}}Q Qb2 3.Qa8 Qxc1 (Qxb3 4.Qf3#) 4.Qf3#
|1...a1{{=}}R 2.f8{{=}}R (2.f8{{=}}Q? a2 3.Qa8 [[stalemate]] (3.Qf6 stalemate)) a2 3.Rf6 Kxh4 4.Rh6#
|1...a1{{=}}N 2.f8{{=}}N (2.f8{{=}}Q? Nxb3 3.Qa8 Nd4 and no mate) a2 3.Ng6 Nxb3 4.Nf4#
}}

This is not a full Babson, however, because 1...a1=B 2.f8=B does not work; White must instead play 2.f8=Q, with similar play to above.
