playBunny: draw and play again would be the easiest ... but this would make you both start at 0 .. losing the advantage wayne might have now (although with his piece captured, he must be lucky to cover his other 2 advanced pieces)

the most fair option would be to ask fencer to move the game back in time, and give you 1+3 (but i dont think thats possible, the dice cant be edited i think?)

or play on and have a game with a confused move in it ...

i made a few of those moves in bg when i started playing it (i never played it before i came here), because i didnt know it wasnt allowed (wayne of course did know which changes this case slightly) .. so it wont be the only game with this type of move

anyway .. when both parties agree on any of the options .. then noone else would be needed to offer opinions

(i sometimes am a referee in squash and use the rule that if i doubt but both players agree on something .. then i wont change that agreement ... unless i am 100% certain of an error :)
