should either decide that the deal
is to stand, the surplus card at the end of the hand is considered to
have been played to the imperfect trick, but does not constitute a
revoke therein.

82. When any one, except dummy, plays two or more cards to the same
trick and the mistake is not corrected, he is answerable for any
consequent revokes he may have made. When during the play the error is
detected, the tricks may be counted face downward, to see if any
contain more than four cards; should this be the case, the trick which
contains a surplus card or cards may be examined and the card or cards
restored to the original holder, who (not being dummy) shall be liable
for any revoke he may meanwhile have made.

THE REVOKE[27]

83. A revoke occurs when a player, other than dummy, holding one or
more cards of the suit led, plays a card of a different suit. It
becomes an established revoke if the trick in which it occurs is turned
and quitted by the rightful winners (_i.e._, the hand removed from
the trick after it has been turned face downward on the table); or if
either the revoking player or his partner, whether in turn or
otherwise, lead or play to the following trick.

[27] See Law 73.

84. The penalty for each established revoke is:--

(_a_) When the declarer revokes, his adversaries add 150 points to
their score in the honor column, in addition to any penalty which
he may have incurred for not making good his declaration.

(_b_) If either of the adversaries revoke, the declarer may either
add 150 points to his score in the honor column, or may take three
tricks from his opponents and add them to his own. Such tricks may
assist the declarer to make good his declaration, but shall not
entitle him to score any bonus in the honor column, in the case of
the declaration having been doubled or re-doubled.

(_c_) When more than one revoke is made by the same side during the
play of the hand the penalty for each revoke after the first, shall
be 100 points in the honor column.

A revoking side cannot score, except for honors or chicane.

85. A player may ask his partner if he has a card of the suit which he
has renounced; should the question be asked before the trick is turned
and quitted, subsequent turning and quitting does not establish a
revoke, and the error may be corrected unless the question is answered
in the negative, or unless the revoking player or his
