I was talking about a task problem. The position has 1 white king, one 
black king, 4 neutral pawns, and one extra piece to avoid a cook. This 
piece can be a white pawn or a black knight.

I've solved the issue by sending both versions to the editor and let him 
choose which is the more economical :).
