When the defending king supports its pawn from the "wrong" [[Pawn Spans|luff-side]], including occupying its [[Promotion Square|promotion square]],
the <span style="background-color: #c0ffc0;">winning area</span> for the attacking king is enlarged by at least one move, in luff-direction even two moves.
The critical luff-side square is now one more file farther away (i.e. for black pawn on c2, e2), and both squares need one critical square needs to be reached in two moves now,
to either transpose to a winning [[#Lee|lee-side case]], or to assist in a checkmate on the luff-side.
