also called '''Attack Tables''', refer to data-structures, most often [[Array|arrays]], containing [[Attacks|attack or defend ]] information for every pawn or piece and/or the transposed information for each square, which pieces [[Square Control|control]], that is either attack or defend it. These Maps are useful for [[Evaluation|evaluation]] purposes such as safe [[Mobility|mobility]], [[Static Exchange Evaluation|SEE]] and of course [[Move Generation|move generation]]. While the piece centric attack information, a set of attacked squares per piece, is often encoded as [[Bitboards|bitboard]], there are more alternatives for storing the square centric information, about attacking pieces.
