This is basically about how to calculate [[Attacks|attack-sets ]] of [[Sliding Pieces|sliding pieces]] for [[Evaluation|evaluation]] and [[Move Generation|move-generation]] purposes. While the attack-sets of [[Pawn|pawn]], [[King|king]] and [[Knight|knight]] are only dependent on their [[Origin Square|origin square]], sliding pieces like [[Rook|rook]], [[Bishop|bishop]] or [[Queen|queen]] have to consider [[Occupancy|occupancy]], as [[Pieces|pieces]] may block the attack-ray in one particular [[Direction|direction]].
