DUMMY
As soon as a card is led, whether in or out of turn, the dealer's
partner shall place his cards face upwards on the table, and the
duty of playing the cards from that hand, which is called Dummy,
and of claiming and enforcing any penalties arising during the
hand, shall devolve upon the dealer, unassisted by his partner.
After exposing Dummy, the dealer's partner has no part whatever
in the game, except that he has the right to ask the dealer if he has
none of the suit in which he may have renounced. If he call
attention to any other incident in the piay of the hand, in respect of
which any penalty might be exacted, the fact that he has done so
shall deprive the dealer of the right of exacting such penalty
against his adversaries.
If the dealer's partner, by touching a card, or otherwise, suggest
the play of a card from Dummy, either of the adversaries may, but
without consulting with his partner, call upon the dealer to play or
not to play the card suggested.
When the dealer draws a card, either from his own hand or from
Dummy, such card is not considered as played until actually
quitted.
A card once played, or named by the dealer as to be played from
his own hand or from Dummy, cannot be taken back, except to
save a revoke.
The dealer's partner may not look over his adversaries' hands,
nor leave his seat for the purpose of watching his partner's play.
Dummy is not liable to any penalty for a revoke, as his adversaries
see his cards. Should he revoke, and the error not be discovered
until the trick is turned and quitted, the trick stands good.
Dummy being blind and deaf, his partner is not liable to any
penalty for an error whence he can gain no advantage. Thus, he
may expose some, or all of his cards, without incurring any
penalty.
EXPOSED CARDS
If after the deal has been completed, and before the trump
declaration has been made, either the dealer or his partner expose
a card from his hand, the eldest hand may claim a new deal.
If after the deal has been completed, and before a card is led, any
player shall expose a card, his partner shall forfeit any right to
double or re-double which he would otherwise have been entitled
to exercise; and in the case of a card being so exposed by the
leader's partner, the dealer may, instead of calling the card,
require the leader not to lead the suit of the exposed card.
