No.742 
No.742 by Sébastien Luce – A new interpretation of Albino theme shown in No.725, but this time with a neutral pawn and a neutral Excelsior in Anti-Circe! (JV)
Definitions:
Anti-Circe: After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). Captures on the rebirth square are allowed. Game array squares are determined as in Circe.
Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.

The logic behind the sequential albino is worth noting:
1.cxb3 is practically forced. Then 2.bxc3 is necessary, as 3.bxc4? or 3.bxc5? would leave the nP stuck on c2 (because of the “pin” from Rc3). Then 3.cxd3 can and must be played, as 4.cxd4? would leave the nP stuck on d2. Now 5.dxc4 is practically forced, and the next step must be to capture the bR guarding g4. The end is then easy – apart from the elegant trap 14.c8nR? noted by the Composer.
bPb5 remains to be explained. It stops a cook with 1.cxb3 6.b8nQ 8.Kxd4 10.Kf3 11.nQe8 12.Kg4#.
Thank you Kjell for these clear explanations.
