Progressive-backgammon thoughts; it starts as usual retro-chess, uncapture is mandatory when one has a piece 'of board'. A (1) move is either an uncapture by moving an opponents piece of ones one. Or a movement move of ones one piece, OR! a legal 'Forward' capturing(capture only) of an opponents piece by ones one piece. (Possibly?!) creating a more strategic game after all pieces are on the board and solving the problem of opponents pieces lingering on ones side (prohibiting undoing capturs by uncaptureings (bye same piece)and uncaptures with pieces ones they reaches their 'starting position'.
