In 2002, I composed this joke :
Black is mate, but white allows him a posteriori to capture e.p.
I don't know if we can say that black has only one move.
He has certainly less than one move ! Maybe 0.5 ;-)

White:Ke1,Nc7,Nd8,Bb1,Bd6,Rh1,Pb4,b5,c3,f3,g2,h2 /
(12 + 9)
Helmate in 2 - a posteriori

Black is mate, but
1.axb3 ep O-O (proving a posteriori that last move was not b3-b4) 2.Ta4 Cb7
and mate again.
