Calculates standard chess material values (Pawn=1, Knight/Bishop=3, Rook=5, Queen=9) with piece differential tallies and bishop pair bonuses.
Interactive Board Orientation & Custom Themes
Flip board perspective between White and Black, toggle algebraic coordinate notations, and choose wooden, tournament, or dark mode board palettes.
