    In the game called Chess+ White makes 2 moves, Black makes 2 moves, White makes 2 moves, etc.

    Prove that Black does not have a forced win.

    You mean because WHITE has a forced win instead? In this variation if you are in a position that in regular check would be checkmate, do you get two moves to get out of checkmate? So you can be in check on the first move as long as you are out of check on the second move?

    Nope, I don't mean that.

    if black has a forced win then white could play 1a.Nf3 1b.Ng1 and now they've switched colors so white has the forced win now in contradiction to the assumption.

    NOTE: white could possibly have a forced win (although i'm beginning to think its unlikely)

    That's right, aginis.
    I also doubt White has a forced win.

    There is an interesting chess variant called Progressive Chess.
