The basic set-up of this program will be Microsoft's View-Document model, as I wrote earlier.
Not much in the way a frills are needed, though I would recommend using the static MFC libraries. After all, passing on your program to friends only to find out it woun't run from the lack of the proper libraries is not a good thing. (This will also happen as your developement libraries become outdated.)
Again, in the Mainframe class's PreCreateWindow(), the 'FWS_ADDTOTITLE' style needs removal.
PS. There was an additional class I neglected to mention last time, CInfoDisplay. This class is more an aid to memory for the user as there is no easy way to tell the playing pieces apart except for the colour. If you prefer you can mark the playing pieces appropriately, but follow along for now.
