5 - h#2 2 solutions isardam anti-circe

Isardam it is unlawful to place in mutual observation two opposite pieces of the same nature
Anti-circe After a capture, the capturing piece returns to its original square if it is free.
If the resurrection square is not free, then capture is illegal

The g1 square will have to be vacated for Nb3 to check.
But it is necessary to forbid the defences ...b1R & ...d1B paralysing the Knight b3 by the isardam condition.
Note that ...Kxa4 is impossible : rebirth on e8 runs into Nxe8 reborn on b1.
And ...cxb3 is also impossible (no rebirth on b7).
