BishBosh.State.Position

AUTHOR

DESCRIPTION

• Defines the state of the game, without regard to how it arrived there; https://www.chessprogramming.org/Chess_Position.
• Games with the same position may be considered to have converged, since they now have equal opportunity.
• N.B.: pieces are fungible, i.e. they lack identity, so the location of identical pieces may be exchanged, without altering the position.
