In response to a challenge suggested by Guy Haworth and Marc Bourzutschky:

White Ke1, Rh1, Bd5, pawns b3,b4,c2,d2,d3,e4,f2,f4 = 11
Black Kh8, Bh7, pawns a3,a7,c6,c7,d7,f3,g7 = 9

. . . . . . . k
p . p p . . p b
. . p . . . . .
. . . B . . . .
. P . . P P . .
p P . P . p . .
. . P P . P . .
. . . . K . . R

White to move: Black wins
Black to move: White wins
But it's not the obligation to move *next* that's at issue...
