The Problemist, 2000

S#3
LEO h8:
PAOs f3; c2:
VAO e3;
MAOs b3; b2 

1.Qf8!   ()

1...LExh2 2.Qxg7+ LEe5 3.Qf6 LEd4#
1...LEg8  2.Qc8+  LEc4 3.Qc6 LEc5#

The key gives the black LEO a second move. In each variation, the black LEO is forced by check to pin itself, after which it is squeezed to become a hurdle from the black VAOe3. This was published with a useless extra white pawn, which was spotted by eagle-eyed Israeli solver Alex Ettinger. This version omits the embarrassing flaw.
