manchildstein: A canon like in chines chess, could be very intersting, but I do not think that the creator will add pieces in the near future. Only some strange pieces which can only move or block other pieces are added and other pawns are added as all diagonal forms of the 6 pawns mentioned. By the way, also the clown is a piece like the squirrel. In fact it is the same as the baron,. but as all crypto-spies you can change them for one of the spies. That could be very inetersting, specially when your crypto-spy is on the seventh row. Note that all spies are allowed to promote.
