Hmm - you don't ask much, do you? :-)
But you might take a look at the pip counts. If you have the pip count
before a roll, then as chequers are moved (or put back), the count
changes to reflect what's been used. From that, you can determine if
any move has been made and if there's any unused movement left in the
dice (although it won't tell you that you have no further legal moves
left). This also works with doubles.
Call PipCount() in eval.c just after the player rolls in CommandRoll()
and save it somewhere. Anytime you need to know if there's anything
used/left to play, call PipCount() again and compare the values.
