No.530 by Karol Mlynka – Non-standard AUW with a use of royal neutral Pawn! (JV)
Problem can be solved with Popeye versions starting 4,61 and older. The last versions 4,63 & 4,65 give error: “too much fairy chess for neutral pieces; problem ignored“.
Chameleon Chess: All pieces on the board which are displayed as orthodox Q, R, B, S, are Chameleons. A Pawn can promote only in Chameleon-pieces.
Anti-Andernach: A piece (excluding King) changes its color after any non-capturing move. After capture, the piece retains its color. Rooks on a1, h1, a8 and h8 can be used for castling, provided the usual other rules for that move are satisfied. After castling, Rooks do not change color, If White makes a non-capturing move with neutral or halfneutral piece, that piece becomes black and vice versa.
Royal piece: Piece that executes a function of the King on the board.
