I had noticed that Ralf's TT5 B2/7/38 problem has the same solution if the Circe condition is removed (ImmunChess only, that is). It may be interesting to explore a bit the stand-alone ImmunChess condition, thus I created a new workshop for this. I have also posted a first problem, a ser-h=81!
If interested in joining the workshop, please request access by joining the ImmunChess usergroup.
