Huh. Do you allow the player to change their plan, now that they know their attempt at forgery is probably not going to work?
By "here" do you mean in this narrative situation, or in conjunction with your preferred resolution mechanics? I assume not the former, because that is obviously false. And I'm pretty sure it's safe to say that different approaches to resolving challenges won't always mix well, so I'll agree with you on that one.
There’s nothing to change. If they tried again, they would get the same result.
I go a step further and simply use dice towers. You don’t know your result. Solves that problem.
But to turn it around, would you allow the arm wrestler to reroll?
And the point still stands. There is no fail condition for an opposed check.
