skipinnz: If the score was 4-1 (since 4-0 would have to be crawford round) and you doubled me in the position you described, I'd accept and redouble you back. This is because there is a theoretical chance that i'd win.

As soon as winning was impossible I would resign. That is the step most players here miss. I too get really annoyed when I have to keep rolling when the outcome is already decided.
