DESCRIPTION

• The relative values of the various ranks of chess-piece.
• https://en.wikipedia.org/wiki/Chess_piece_relative_value#Hans_Berliner.27s_system%20Chess-piece%20relative%20values

Types

Data-types

data RankValues

• The constant value associated with each rank; the higher, the more valuable it is considered to be.
• N.B.: only relative values are significant; the absolute value associated with any rank is irrelevant; typically ranks are valued in centipawns.
• CAVEAT: a King can never be taken, but assigning the value infinity creates problems, so typically it has the value 0.
