COMMON RULES AND MANNERS OF DUPLICATE BRIDGE
1. Complete your Convention Card before the game, ensuring both you and partner are playing identical cards.
2. Arrive at the game early, locate your partner and check in with the Director and offer to help with pre- game logistics.
3. Make your opening lead before writing down the auction. Everyone is waiting for you.
4. As Dummy, do not linger before facing your cards after the opening lead. Everyone at the table is waiting for you. You can write down the auction after facing your cards on the table.
5. North should score the board immediately after play. Post-mortems are best saved until after the round if time allows.
6. When the Director has called a round change, leave the table if the pair behind you is waiting.
7. Refrain from opening up the traveling score-slip if you still use them and loudly reading out the results achieved during previous rounds or discuss your result where players at other tables can hear you. Now is not the time to broadcast your result, maximum attainable result, opening lead, defense, misplays, etc.
8. If you are late finishing a board, pass the prior boards played to the next table. If you were not considerate enough to at least pass one board while the next table is waiting and are not sure who should get the boards, it's easy to determine - that's probably the person glaring at you from the adjacent table.
9. If you are late either arriving at the table or leaving the table, quickly sit at the next table, pull your cards and begin bidding. Now is not the time to take a break, engage in idle conversation, discuss prior boards with partner, etc.
10. Maintain a courteous attitude to everyone (partner, opponents, director, kibitzers and teammates).
11. Ensure any conventional bids used by you and your partner are alerted. Make sure your convention card is legible with correct entries in the appropriate location on the card.
12. Do not attempt to see the place from another player's hand from which the player pulled a card in playing. For instance, should an opponent or partner sort their cards by suit in descending order from left to right, we should not note positional relationship of adjacent cards played in order to deduce a player's holding.
13. Make your bids and plays in tempo. Using special emphasis, inflection, gestures, facial expressions, and the like may provide your partner unauthorized information about your hand. Do not draw inferences if your partner has done any of the above.
14. Consistently announce skip bids or use the stop card before making a jump bid. This allows your Left Hand Opponent additional time to prepare for their bid, ensuring your Right Hand Opponent will not receive unauthorized information associated with a possible hesitation. The Left Hand Opponent typically waits about 10 seconds before making a call, using the interval to contemplate a well considered bid and shows the appropriate demeanor.
15. Make clear claims when it is your turn to play, facing your cards and providing the exact line of play, especially the treatment of outstanding trumps.
16. Do not detach a card before it is your turn to play; doing so provides unauthorized information to your partner. Do not play to a trick before it is your turn to play.
17. Remember that the Director is available to help everyone.Call the Director at the first sign of an irregularity, doing so with a friendly "Director, please." voice. Never make your own rulings.
18. It is not your duty to call attention to your own breach of law, such as a revoke, lead out of turn, or hesitation, made by you or your partner.
19. Unless there is an emergency, you may not leave the table till the round is completed.
20. All cell phones must be turned off when entering the bridge room.
21. During the bidding, do not touch the bidding box until you have made your decision. Touching different parts of the bidding box and hesitating gives your partner unauthorized information about your hand.
