No.310 by Nicolas Dupont  – This is the 3rd Proof Game at Julia’s Fairies! For now doesn’t participate in the informal tourneys announced, but in case of more entries coming the separate tourney for them might be announced at the end of year 2013! Again, enjoy a very detailed explanation by the author! (JV)


Circe Parrain: After a capture, the captured piece is reborn only after another piece of its own side has moved. The line between capturing square and rebirth square is parallel with and of same direction and length as the move of this other piece. Pawns can be reborn on 1st and 8th rank. From their own base rank, they may move one-step; if reborn on the promotion rank, the Pawn at once promotes, the promotion piece being determined by the Pawn side.
