Expected In-Behavior Just as all kinds of competitive-type endeavors have their expected in- behavior, so does duplicate bridge. One important thing to keep in mind is that this is a competitive adventure.....as opposed to the social outing that you may be used to at your rubber bridge games. Now that is not to say that you can=t be sociable at the duplicate table. Of course you can.....and should.....just don=t carry it to extreme by talking during the auction or play. -

Bridge Glossary
Bridge Glossary Above the line In rubber bridge points recorded above a horizontal line on the score-pad. These are extra points, beyond those for tricks bid and made, awarded for holding honour cards in trumps, bonuses for scoring game or slam, for winning a rubber, for overtricks on the declaring side and for under-tricks on the defending side, and for fulfilling doubled or redoubled contracts. ACOL/Acol A bidding system commonly played in the UK. Active An approach to defending a hand that emphasizes quickly setting up winners and taking tricks. See Passive Advance cue bid The cue bid of a first round control that occurs before a partnership has agreed on a suit. Advance sacrifice A sacrifice bid made before the opponents have had an opportunity to determine their optimum contract. For example: 1♦ - 1♠ - Dbl - 5♠. Adverse When you are vulnerable and opponents non-vulnerable. Also called "unfavourable vulnerability vulnerability." Agreement An understanding between partners as to the meaning of a particular bid or defensive play. Alert A method of informing the opponents that partner's bid carries a meaning that they might not expect; alerts are regulated by sponsoring organizations such as EBU, and by individual clubs or organisers of events. Any method of alerting may be authorised including saying "Alert", displaying an Alert card from a bidding box or 'knocking' on the table. Announcement An explanatory statement made by the partner of the player who has just made a bid that is based on a partnership understanding. The purpose of an announcement is similar to that of an Alert. -
