Only intersection with the opponent pieces is required.

We may include a possible [[En passant|en passant]] target square.

==Attack Maps==

</pre>

Those attack maps are among other things useful to decide about [[Candidates (Bitboards)|candidates]] and [[Backward Pawns (Bitboards)|backward pawns]] .

==Captures==

As usual, capture targets are the intersection of attack-sets with opponent pieces. Except [[En passant|en passant]] captures of course. A reverse shift of disjoint direction-wise sets obtains the pawns which may capture.
