Sorry Greg, but I did not made myself clear enough. I meant the joker. If the joker should be allowed to move ahead when imitating a pawn, or backward. This was the quenstion. I always took it for granted that the imitation was to be ahead, but technically speaking a white joker imitates a black one who moves backwards. Letting it to move ahead (as it comes natural to me though) would be an exception the the main rule that the joker imitates enemy pieces. Technicalities aside I still think that moving ahead is better.
