Thad: I agree with Thad - the game how it is now is beter played with people who have time to keep track of things in the notes - where for someone like me who likes to play fast, it takes too much time messing with 1 games.
Also like Thad said, if the captured pieces is unkown, then mark it with a ? - only if it was revealed with a spy first should the actuall captured pieces be shown (or beter yet, show what the pieces was captured with - so if it was captured with a 2, then a ?-2 - that way you know it was either a 1, 2, spy, or sapper) - but I would be happy with just a ?
