This is a neat idea! I particularly like the care that was taken to avoid allowing indirect checks by double-moves. (IE, the King being in check by a combination of both the opposing player's moves.) <p> I'll note pedantically that while this game might have been inspired by Alice Chess, it doesn't have the defining (to me) characteristic of Alice Chess that moving forces a change between boards. I would describe this more as a two level 3D Chess variant. <p> Chancellor and Marshall are both common names for Rook+Knight. The common name for Bishop+Knight is Cardinal, although Archbishop and Princess are used in a fair number of games as well (although Archbishop is also used for other Bishop variants). <p> A game with 6x7 square boards, double-moves and swapping pieces? This game vaguely resemble a distant cousin of <a href='..//42.dir/mulligan-stew.html'>Mulligan Stew Chess</a>.

A question: <p> <ul> <li>May a King move into check with the first move of a turn, if the second move of the turn removes check?</li> </ul> <p> I'm attempting to write a ZRF for this game (in a case of fortunate timing I wrote a ZRF for a non-competing entry I'm thinking of making with the same board), but I'm not sure how close I'm going to be able to get. Zillions' checkmate handling is hardcoded, and doesn't really work well for multimove games.

Another question, this time about en-passant captures. <p> Just when is en-passant allowed? There are four cases (I'll assume for discussion that White is moving, and Black is capturing): <p> <ol> <li>White moves the Pawn in the first move of their turn, and Black captures in the first move of their turn.</li> <li>White moves the Pawn in the first move of their turn, and Black captures in the second move of their turn.</li> <li>White moves the Pawn in the second move of their turn, and Black captures in the first move of their turn.</li> <li>White moves the Pawn in the second move of their turn, and Black captures in the second move of their turn.</li> </ol> <p> Any or all of the above cases could be allowed. <a href='../multimove.dir/doublemove.html'>Double Move Chess</a> and <a href='../multimove.dir/marseill.html'>Marseillais Chess</a> allow cases 1 and 3, with the special rule that if both of White's moves allowed for en-passant capture, Black may take both of them. <p> What does Tandem-84 use? <p> Case 3 is the simplest, as their are no intervening 'moves' to confuse the issue. It would seem to me that given the board width of 7, where a Pawn making its initial move arrives in position to capture en-passant, making en-passant too easy would weaken the Pawns.

another impressive game. as i've mentioned previously elsewhere, games that use standard chess pawns and boards with an odd number of rows tend to be unbalanced, but this problem is eliminated by the double-board aspect of the game. in most of my games, one player was able to get a slight upperhand on one board while the other player gained control of the other board, altho this is somewhat of a generalization. <P> the tactics in this game quickly become complex and intense, and therefore zillions plays the game well. pawn endgames are particularly interesting because pawns can dodge threats by jumping from board to board. the ghost works well and is easy to visualize and remember (i know aikin discarded several other versions of the ghost before picking the final ghost).
