What happens if the pack is exhausted?
Although I am no authority, I can find no other guide to the question online. The rule I have played for twenty-five years is that it is unfair (and dull!) to end the game while a win may still be forced. Therefore, I play that “taking a card” in this situation becomes an effective pass, and that if three of these occur in a row, it is only then that the game is declared a draw.
