<>I cannot see any imbalance in this setup only because the early attack with the chancellor against the "weak" point c7 is not a good plan.

Right this is not the reason, but there is an imbalance in this setup for another reason.
When white plays: 1.Cc3 then black should immediatelly has to play one move to reject it! He can not play from the King's side as he would lose(or anyway he would have an important disadvantage). This restriction of freedom for the black's choices, is a huge drawback of this variation.

This means that on a game, whatever first move white will make, black should have the option of making many various moves and not be restricted to few.

>I would say better : Black is okay ,no fast refutation is possible and the setup is playable.

Right, no fast refutation is possible, and the game is playable but since there is the aforementioned inaccuracy in this game, something Gothic chess doesn't have, we should prefer the second for playing.


>Show us a plausible move sequence which is suitable to force a win for White.And only than you perhaps can substantiate,that the setup is inplayable.

As i've said the game is playable, but it is inferior to Gothic Chess since the lack of freedom in black's 1st move when white plays 1.Cc3 is decisive.
