What IS duplicate bridge?
How it works
It is possible that when you and your friends gather to play bridge, it is a casual game and you play rubber bridge and use rubber bridge scoring.
When there are several tables of players, they often play duplicate bridge. Instead of dealing the cards each hand, the players take their cards from a duplicate board. As a card is played, they don't toss it in the center but each player puts his card face down in front of himself so he can later return his entire hand, intact, back to the board for the next table to play. It's easier to understand with some pictures!
How long is a game?
You will play anywhere from two to five hands against the same opponent during a round. At the end of the round, you will move to a different table to meet new opponents and the boards will move on to be played by other competitors. A session of duplicate usually lasts about three hours.
Your final score is a result of how many other pairs in your direction that you managed to beat or tie. On each hand, you get one point for every pair you did better than and a half point for every pair who had the same result as you did. If you are in 3N and make exactly nine tricks, but everyone else was in 3N and made ten or more tricks, you will get a zero on the board -- even though you bid and made a game! Several players have asked how can you check your scores in a tournament. Click to find out.
One nice thing about duplicate is: It doesn't matter how bad (or good) your cards are! Everyone gets the same cards. What does matter is how well you did with the cards you were dealt.
team consists of two pairs. One pair plays North-South for a designated number
of boards and the other plays East-West for the same boards at a different
table. Then the scores are compared
Teams. This is a team
event in which one team plays an entire session against one other team. The
winning team from each match advances to play the next round and the defeated
team is eliminated.
Teams. Each team will
play approximately 6 to 9 board matches against a number of other teams during
the event. Matches are arranged by pairing teams with approximately equal
How team scoring differs from regular duplicate.
In a Team Game, each time you meet a new opponent, it is called a match. At the same time as you are playing your hands, at another table, your teammates are also playing the same hands -- but they will be playing them in a different direction at another table. If you are sitting North and South at your table, your teammates should be sitting East and West at the other table. The teammates of the people at your table will, likewise, be sitting in the opposite direction at the other table. There are no travelers; each player must keep track of the results of the boards. Usually, before you leave your opponents, you verify that you have all recorded the same results.
At the end of each match, you and your teammates will compare scores. On each board, you add up the total amount of points your team won (or lost). If you bid 3N and made exactly 9 tricks, you would score 400 (600, if you were vulnerable). Meanwhile, at the other table, your opponents playing the same hand bid 3N but made 10 tricks for -430 (or -630) for your teammates. Your total score on the hand would be -30. You would then look at the bottom of your score card and using the IMP (International Match Point) scale, convert that to IMPS. That is the score you will get on the hand. When the score is within 10, you get zero IMPS (this is a tie or push board). After you have converted all your scores to IMPS, you add up the total wins and losses. That becomes the result of the match -- you won or lost by so many IMPS (or tied).
At the end of each match, the results are given to the director who then decides which teams will play against each other in the next match -- or in a Knockout match, which team will move on and which team is now out of the event. In Swiss teams, if there are enough teams in play, the director will try to match a winning team against another winning team and a losing team against another team who has lost.
In Team Games, it is important to bid and make your games. If you have a sure way to make your contract, take it! Risking everything to try for an overtrick (a not uncommon matchpoint or duplicate strategy) is a losing proposition in a team game. Whatever your opponent's contract is, you should usually stand on your head to try to beat it. An overtrick is worth virtually nothing -- one IMP or so but beating a contract is often worth a lot. In our example hand, let's say your teammates allowed their opponents to make an overtrick (you lose 1 IMP) but, if the cards had been distributed a little differently, they would have beaten them (worth 10 or 12 IMPS). Certainly worth the risk!
One way the American Contract Bridge League rates its member's progress is through the master point plan. From the ACBL site:
"Generally, the more masterpoints a member has, the more experienced and skilled he or she is assumed to be."
If you want to know more about the master point levels, click here.
Want to earn master points more quickly? Club
games pay 0.10 per pair
sitting your way or overall. For example, if there are 10 tables, first place
will pay 1.0 masterpoint. In a
5-table Howell, where you play four other pairs, first place your way pays 0.5.
