A different method which may work is saving the initialboard in the game
file.  In the Init() method, randomly create the board if it is not there
(new game), or leave it the same if it is already there (undo).

By replay, are you talking about the "game show board#move" syntax?
That works even if the game has forfeits.  (Actually I just noticed that
ChineseCheckers has a problem with that syntax which can occur on forfeits
_and_ resigns.)
