From the developer:
ThudBoard is a computer application that can be used to play Thud battles without using the actual board.
The main purpose of ThudBoard is to facilitate online gaming, where people communicate moves by sending each other board-coordinates. Using the ThudBoard these moves can be carried out, and whole battles can be saved either as a series of moves or as a board position.
