DOUBLE DUMMY
The rules are the same as in Dummy Bridge, with the following
exceptions:
The dealer deals for himself each time, never for his Dummy; and
the hand on his left always leads first, and has the first right of
doubling.
Neither player may look at more than one of his two hands before
the first card is led, excepting in the case of the dealer when the
call is passed to Dummy.
Either player is liable to the penalty of a revoke in his own hand,
but not in his Dummy.
