The auction comes from Japan v Germany for the Venice Cup (Round 11). At the other table, East raised to 2H and Auken-vonArnim went all the way to 5S, but stopped there. So the board was flat at 480.
Actually, this was the _flattest_ board in the whole round robin: out of 66 tables, the score was 480 in 63 of them! Only two pairs bid the slam: the SouthAfrican women and the open pair of Trinidad (the other non-flat score was a 450).
Still, the slam is laydown. Is it as unbiddable as it seems?
