The shifted intermediate sets are likely [[General Setwise Operations#Intersection|intersected]] with some mask to avoid board wraps of certain directions, and/or also to consider the [[Occupancy|occupancy]] or any reasonable taboo set (i.e. [[Pawn Attacks (Bitboards)|pawn attacks]]) as flood stopping obstruction.
