Play Embassy Chess with Jocly
Embassy Chess is played exactly like Chess except for the introduction of two new pieces, a couple extra Pawns, and a new castling rule. The two new pieces are the Cardinal (a compound of Bishop and Knight) and the Marshall (a compound of Rook and Knight). The new castling rule is that the King moves three spaces toward the Rook when castling. Otherwise, the usual castling restrictions apply.
Contrary to the way castling is normally implemented on Jocly, castling is handled by moving the King to the space it will move to, not to the Rook's space.
