Detailed Description

Details of a board transition caused by a move.

This class stores information about the movement of pieces and changed squares on a chessboard. Two types of information are stored: movement, and changed squares and reserve pieces. The latter type of information is sufficient for updating the state of a graphical board, and the former can be used to display or animate the actual chessmove.
