4 - h#2 - Einstein - 2 solutions

after a capture, the capturing unit is transformed as follows: P?S?B?R?Q?Q.
After a non-capturing move the moving unit is transformed as follows: Q?R?B?S?P?P.
Castling, which is also possible with a newly-transformed rook, results in the rook transforming to bishop.
Pawns on their back rank may move 1, 2 or 3 steps and are subject to en passant capture if moving more than 1 step.
There is no normal promotion on the 8th rank.

9 - h#2 - AntiCirce - 2 solutions

a unit (Ks included) which makes a capture is immediately reborn
(on the same square in which it would be reborn if it were the captured unit in the corresponding Circe variant).
The rebirth square must be vacant, otherwise the capture is not legal.
(A threatened king capture is only check if the capturing piece can be reborn).
By default, a unit may capture on the same square as the square upon which it is to be reborn.
The same rules for Ps, Rs and Ks as for Circe apply
