Solution by Reed Truitt:
Black has only captures, pawn moves, and checks that require White to capture. Therefore it is White to move.

Very pleasant. We quickly see what are black moves, but we wonder what will be the white moves: the white Knight must protect the black King, while white Bishop has a long way before being captured, as well as the white Queen.

As Pronkin did, once with the Knight, once with the Bishop! The black moves are the same, with a small difference in the order. Quite nice.
