Commonly, '''X-ray''' in Chess refers to a family of several tactical motives, where a [[Sliding Pieces|sliding piece]] [[X-ray Attacks (Bitboards)|attacks through]] any other [[Pieces|piece]] in a [[Direction|ray-direction]]. In particular, a '''X-ray''' refers to an indirect defense, where a sliding piece conditionally defends an own piece, which is attacked by an x-rayed opponent sliding piece from the same [[Direction|direction]]. X-ray and [[Battery|batteries]] may be subject of [[Static Exchange Evaluation|static exchange evaluation]].
