AlgebraicNotationPoint2D is an extension of javafx.geometry.Point2D for a chess game. Notably it creates a new constructor with a char, double signature for standard algebraic piece notation in chess. It contains a private static converter method which turns the char into a double value representing it's alphabetical index starting at 1. The cha…
