Interesting presentation in Duplex. Good idea !

Since both BQb1 & WQg8 cannot move (as they are not threatened), can they threaten the opposing piece(s) ? 🙂
The term “observed” is actually better than “threatened”.
In Functionary Chess (Beamtenschach to the Germans), a piece that is not observed by a piece from the opposite side cannot move – but it can still observe!
Thanks you! I think ‘observed’ is apt here.

This version doesn’t seem to work. In the W to play part there is always 6.Kb4 or Kb5 that cut off the observation of the rooks.
