I think Fencer is aware of the dice problem in gammons? I'm sure I've seen it discussed on the backgammon board, but I could be wrong.
If this is the problem then its not eactly cheating... well, it is but the programme here allows it (for now), so it can't be helped.
I meant if there is an outside programme being used or anything like that. If it is just a disagreement on the dice then its best sorted with a polite message to your opponent. It may be they had not noticed the move?
