With this Albino.cql studies are found with an albino pawn. Created by Peter Boll. Converted by Lewis Stiller to CQL 5.1

; Albino pawn = A white pawn on its starting square makes each of its four possible moves 
; (forward one square, forward two squares, capture to the left, capture to the right). ; Because only studies with a black pawn having these kind of moves are found this cql is with flipcolor.  ; Of course most of these different moves are found in variations.
