No.394 by Peter Harris – Two neutral pieces, two fairy conditions and two solutions! (JV)


Sentinels Pion neutre: When a piece (Pawn excluded) leaves a square outside the first and last rows, a white piece leaves a wP, a black piece leaves a bP and a neutral piece leaves a nP unless 8 Pawns of that color are already on the board.

Super-Circe – When captured, a piece is reborn on any free field on the chess board without causing self-check or selfmate. Possible is also removal of captured piece from the board. The Pawns (white, black, neutrals, half- neutrals) can be reborn on the first or eight row also. When reborn on the first row  (for Black) or on the eight row (for White) the promotion is obligatory. When reborn on the first row  (for White) or on the eight row (for Black) the Pawns are immovable.

It has already been reported to the Popeye development team that the latest Popeye v4.63 has trouble handling neutral pawns with some fairy conditions: within the same move Popeye treats such a pawn both as black and as white (in the present problem, nPa3 is captured by nK and reborn at b1 as nR and at b8 as nR too).
The same issue occurs with other fairy conditions of the Circe family.

As far as I know, Thomas Maeder & Co. are working on fixing these bugs (and have already fixed many of them in the new beta version). We must be patient until the next release.

Would love your thoughts, please comment.x
