rod03801: I resign as soon as I can't change the result (so for instance when I avoid the gammon but can't win). There is no etiquette to the contrary, in fact over the table you would always stop the game and quickly start the next frame in the set.
and i never say gg until the MATCH is finished, not the frame.
