39. In all cases where a penalty has been incurred, the offender must await the decision of the adversaries. If either of them, with or without his partner’s consent, demands a penalty to which they are entitled, such decision is final. If the wrong adversary demands a penalty, or a wrong penalty is demanded, none can be enforced.
The following rules belong to the established code of Whist Etiquette. They are formulated with a view to discourage and repress certain improprieties of conduct, therein pointed out, which are not reached by the laws. The courtesy which marks the intercourse of gentlemen will regulate other more obvious cases.
1. No conversation should be indulged in during the play, except such as is allowed by the laws of the game.
2. No player should in any manner whatsoever give any intimation as to the state of his hand or of the game, or of approval or disapproval of a play.
3. No player should lead until the preceding trick is turned and quitted.
4. No player should, after having led a winning card, draw a card from his hand for another lead until his partner has played to the current trick.
5. No player should play a card in any manner so as to call particular attention to it, nor should he demand that the cards be placed in order to attract the attention of his partner.
6. No player should purposely incur a penalty because he is willing to pay it, nor should he make a second revoke in order to conceal one previously made.
7. No player should take advantage of information imparted by his partner through a breach of etiquette.
