No.549 (SL)

No.549 by Sébastien Luce – AUW in a problem with uncommon fairy condition Anti-Circe Couscous (in WinChloe only, where the default type for Anti-Circe is Cheylan!). (JV)

Definitions:

Anti-Circe Couscous (WinChloe): As Anti-Circe Cheylan, but the capturing piece reappears on the Circe rebirth square of the captured unit. Pawns capturing on their rank of promotion are promoted before the rebirth. Captures on the rebirth squares are not allowed.

Anti-Circe Cheylan: 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 not 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.

It is the first AUW with neutral pawns with this uncommon condition (Winchloé database). (Author)
