If players want to compete, they must agree on rules.

The organised players delegated this to the World Bridge Federation via their

national organisations.

The International Code Laws of Duplicate Bridge - edition 2007 can be

downloaded from: www.worldbridge.org/department/laws (2009).

This set of 91 laws are in print about 40 pages (~30x28cm//8x12 inch)

They are interpreted by national organisations in extensive additional

codebooks ( different names, i.e. orange book )

The Revised 2008 Laws of Duplicate Bridge have no official status (yet).

(see below). They are short and well structured.

They intend to promote bridge by eliminating restricting

rules, introduce tools for easier bidding, but do not touch the very substance

of the bridge game. They were compiled by Paul Hauff.

Players and clubs are free to adapt these laws

The Tournament Organiser is an entity defined by and subordinated to national
law and consisting of one person or group of persons.
One of his activities is to organize and put into effect bridge tournaments. He
accepts the laws and regulations herein outlined.
He nominates the Tournamen Director (TD)

The Tournament Director has the sole and full power to do or initiate all
activities to run a competition of two tables or more.
He is bound to the laws and regulations mentioned herein. The TD might be a


The four players of a cardplay (flight) sitting at a table are called North,
East, South and East (clockwise).
The four players at each table constitute two partnerships (entity or sides)
North-South against East-West. In pair or team competitions the contestants
enter as pairs or teams respectively and retain the same partnerships
throughout a competition (except in the case of substitutions authorised by
the Director). In individual events each player enters separately, and
partnerships change during a competition.
In events with an odd number of pairs, the missing pair might be substituted
by an synthetic pair named " phantom pair ".


Duplicate Bridge is played with a pack of 52 cards, consisting of 13 cards in
each of four suits.
The suits rank downward in the order spades , hearts , diamonds , clubs . The
Cards of each suit rank
downward in the Order Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2.


A duplicate board containing a pack is provided by the TO for each cardplay.
Each board is numbered and has four pockets to hold the four hands,
designated North, East, South and West. The dealer and vulnerability are
designated as follows:

North Dealer Boards 1 5 9 13
East Dealer Boards 2 6 10 14
South Dealer Boards 3 7 11 15
West Dealer Boards 4 8 12 16

Neither Side Vulnerable Boards 1 8 11 14
North-South Vulnerable Boards 2 5 12 15
East-West Vulnerable Boards 3 6 9 16
Both Sides Vulnerable Boards 4 7 10 13

The same sequence is repeated for Boards 17-32 and for each subsequent
group of 16 boards. No board that fails to conform to these conditions should be
used. If such board is used, however, the conditions marked on it apply for that


The bidding box, resp. its content makes silent bidding possible.
All calls are done by using printed bidding cards
They are: pass, double, redouble, or the nominal bid wich
specifies the desired number of overtricks together with suit or notrump.
Bid cards showing the same number of overtricks are said to be of the same


A cardplay consist of joining 52 previous distributed cards (deal) to 13 tricks
and attributing values (scores) to each trick.
A trick score of 100 points or more, made on one board, is called GAME.
A trick score of less than 100 points is called PARTSCORE.


Headings, braceted numbers and signs are not part of the law rsp. rules and
serve for better findig.
The words competition, contest, event, tournament have the same meaning unless


The modern one table tournament replaces the former rubber procedure.
It eliminates fourtuitousness.
Standard procedure: played are boards 1-4 from both sides.
Boardsd might be neutralised to prevent recognition of boards by their outer
The set of boards may include boards whose results will be omitted for winner
One of the player has the funciton of TD for the first inning of four cardplays,
the other side for the replay ( second inning) from the other side.
Adapted boardtraveler are used to note down the result.
Winner is : the side with the highest summed up score,
orthe side having more better results per cardplay then the other.


#P1 Observance of Laws

Duplicate bridge tournaments should be played in strict
accordance with the Laws. The chief object is to obtain a higher
score than other contestants whilst complying with the lawful
procedures and ethical standards set out in these laws.

#P2 Basic Pocedueres and routines

All actions involving all four contestants must be done in rotation, clockwise.
The obligation to follow suit takes precedence over all other requirements of
these Laws.
Communication between partners during the auction and play shall be effected
only by means of calls and plays.
alls and plays should be made without undue emphasis, mannerism or inflection,
and without undue hesitation or haste.

#P3 Infraction of Law

1. A player must not infringe a law intentionally, If he does so, the penalty
is one trick.

2. There is no obligation to draw attention to an unintentionally infraction of
law committed by one’s own side.

3. A player may not attempt to conceal an infraction, as by
committing a second revoke, concealing a card involved in a
revoke or mixing the cards prematurely ( penalty).


The regular penalty is realised by deducting one trick.
If this law shows a penalty for special cases, such penalty will prevail.
If players infringe a law unintentionally, players and TD will agree as follows:
a pair or team is  
no way at fault;
partially at fault;
at fault,
  then the  penalty will consist in awarding an artificial score as mentioned in
table below, see SECTION III TD .

of thirteen cards each; each hand is then placed face down in one of the
four pockets of the board. A member of each side should be present during the
shuffle and deal.

B. New forms
The cards are laid based on outprints of computer generated deals, either at the
table by the contestants, or in advance by the TD.
Outprint might remain systemborn or selected by the TD.

C. Duplicating

The Director may require a different method of dealing or pre-dealing
to produce bords with identical deals.


A. Placement of Board

The defender on declarer’s left makes the opening
lead face down. All bidding cards are removed to the bidding boxes.
After the opening lead is faced, dummy spreads his hand in front of him
on the table, face up, sorted into suits, the cards in order of rank
with lowest ranking cards towards declarer, and in columns pointing
lengthwise towards declarer. Trumps are placed to dummy’s right.
Declarer plays both his hand and that of dummy.


The player who leads to a trick may play any card in his hand
After the lead, each other player in turn plays a card, and the four
cards so played constitute a trick.
In playing to a trick, each player must follow suit if possible.
If unable to follow suit, a player may play any card.
Failure to follow suit constitutes a revoke.
A trick containing a trump is won by the player who has contributed to
it the highest trump.
A trick that does not contain a trump is won by the player who has
contributed to it the highest card of the suit led.
The lead to the next trick is from the hand in which the last trick was
Cardplay ends when the last trick has been played,either effective or by claim.


a) Declarer plays a card from dummy by naming or touching a card, after which
dummy picks up the card and faces it on the table.
In playing from dummy’s hand declarer may, if necessary, pick up the desired
card himself.
Declarer can correct dummis action any time without hesitation.
If declarer has led out of turn from his or dummy’s hand, either defender may
accept the lead or require its retraction.
If the defenders choose differently the option expressed by the player next in
turn shall prevail.

b) Declarer plays his card by detaching it from his hand and
facing it on the table immediately before him, when it is his turn to play.
Declarer might restore his card and play another, even if its face has been
seen by other contestant,
at any time, but without hesitation and the next trick has not been played.

c) Each defendant plays a card by detaching it from his hand and
facing it on the table immediately before him, when it is his turn to play.
If the face was seen by other contestants must be played, if not the card might
be restored.
A player may change an unintended designation if he does so without pause for
thought and the card has not touched the table, and the declarer agrees.

e) A card seen or played out of turn must be restored and results to a penalty
( deduction of one trick ) .
The other contestant may allow to restore without penalty, if all agree.


So long as his side has not led or played to the next trick, declarer or
either defender may, until he has turned his own card face down on the
table, require that all cards just played to the trick be faced.
Until a card is led to the next trick, declarer or either defender may
inspect, but not expose, his own last card played.
When four cards have been played to a trick, each player turns his own
card face down near him on the table.
1. If the player’s side has won the trick, the card is pointed
lengthwise toward his partner.
2. If the opponents have won the trick, the card is pointed lengthwise
toward the opponents.
Each player arranges his own cards in an orderly overlapping row in the
sequence played, so as to permit review of the play after its
completion, if necessary to determine the number of tricks won by each
side or the order in which the cards were played.


He may suggest a play, but only silent by touching a card with his forefinger.
He then must play this or an other dummycard by order of the declare.
Other rights :

a) After play ceases, the played and unplayed cards may be inspected to
settle a claim of a revoke, or of the number of tricks won or lost; but
no player should handle cards other than his own.
A player should not disturb the order of his played cards until
agreement has been reached on the number of tricks won. A player who
fails to comply with the provisions of this Law looses his right to
claim ownership of doubtful tricks or to claim (or deny) a revoke.

b) Agreement on Tricks Won
The number of tricks won shall be agreed upon before all four hands
have been returned to the board.
A player must not knowingly accept either the score for a trick that

If all player have agreed on result, it must be documented in writing,
containing the following:

a) played from (compass direction) b) contract (short); c) result, made or
number of tricks ,d) pair number NS; e) score NS ; f) score EW, g) pair number EW.
If one of the scores is a zeroscore, writing down migth be omitted.
The written document (board traveler) must be kept together with the board to
enable all players see the result of other contestants.
The player seated North should care for the documentation and control of
correctnes of hands.

At the end of the competition the board traverler id forwarded to the TD.
All players are entitled to receive a copy of all boardtravelers either paper or
The TD will keep these documents for one week, or as set by the TO.
The TO and TD might establich additional rules and anotations with each


Any statement to the effect that a contestant will win a specific number
of tricks is a claim of those tricks. A contestant also claims when he
suggests that play be curtailed, or when he shows his cards.
If an opponent of the claimer requests that the claimed rest of the cardplay has
to go on, the claimer must folow.
A claim must be accompanied at once by a clear statement as to the
order in which cards will be played, of the line of play or defence
through which the claimer proposes to win the tricks claimed.

If the claim or concession is agreed, play ceases.The board is scored as though
the tricks claimed or conceded had been won or lost in play.

The Tournament Organiser may establish additional regulation to the processing
of claims.

#C61 R E V O K E
A player must correct his revoke if he becomes aware of his irregularity if the
next trick has not been started.

On the twelfth trick, a revoke, even if establihed must be corrected if
discovered, before all four hands are returned to the board.

A lead out of turn might be accepted by declarer. Dummy plays then card as
Not accepted results to penalty (1 trick), and the lead must be played from the
correct direction.
Declarer may not allow to play a card which sbows the same suit as the wrong
lead card.

When a board has been played and the contestants do restore the hands in the
not ordered compass direction (penalty 1 trick),
the next flight must reset the original deal and inform the TD. The TD will then
assign a just score to the detecting flight.
If the next flight does not detect the error, an the error is detected later,
both sides will earn zero-score.
The TD may neutralize all results of this board by assigning a zero score to all
contestants, but the penalty for the infraction pair stands.

A card seen or played out of turn must be restored and results to a penalty
(deduction of one trick ).
The other contestant may allow to restore without penalty, if all agree.

Unless the Regulating Authority provides otherwise a player may consult his own
system card during the auction period until the end of play. Thw timw is limited to 30 seconds.


a) Partnership understandings as to the methods adopted by a partnership may be reached explicitly in discussion or implicitly through mutual experience or
awareness of the players.

All rights arising from such understandig are sole property of both partners.

Information conveyed to partner during cardplay must arise from the cardplay and
conditions of the current competition.

b) Partnerships have no obligation to disclose such understandings or any other
information about their hands to opponents or other persons. Information give voluntarily to the other players give no rights to such persons .

c) The tournament organiser migth keep a list, where partnerships give
information as to their understandings or usually used proceedings in cardplay.
Such information might be expressed in terms of public know bidding an playing
The tournament organiser might deduct such information from record of played
tournaments, or given freely to them by entities .

Playersd entering a competition must have acess to such information.

No right whatsoever can be deducted from such information.

If two pairs compete, one side makes a score from 50 upwards, ond the other side makes a zero score.
If all four players pass, each side enters a zero score.
In cases of missing scores and similar, the score is set by the TD.
The nominal value of scores might be zero or higher, even for both sides.


Two ways possible:
a: by summing up original scores, modified or not.
The modification can be effected by taking the difference between two scores
deducting there from special points ( called IMP, International matchpoint, or other).
b: comparing scores by value and deducting therefrom matchpoints, or "one point
per cardplay" won.

#W4 METHODS OF SCORING (old law 78 )

A. Matchpoint Scoring

In matchpoint scoring each contestant is awarded, for scores made by
different contestants who have played the same board and whose scores
are compared with his, two scoring units (matchpoints or half
matchpoints) for each score inferior to his, one scoring unit for each
score equal to his, and zero scoring units for each score superior to his.

B. International Matchpoint Scoring
In international matchpoint scoring, on each board the total point
difference between the two scores compared is converted into IMPs
according to the following scale.

Difference Difference Difference
in points IMPs in points IMPs in points IMPs

20–40    1     370–420 9     1500–1740 17
50–80    2     430–490 10   1750–1990 18
90–120  3     500–590 11    2000–2240 19
130–160 4    600–740 12    2250–2490 20
170–210 5    750–890 13    2500–2990 21
220–260 6    900–1090 14   3000–3490 22
270–310 7  1100–1290 15   3500–3990 23
320–360 8  1300–1490 16   4000 & 24 upward

C. Total Point Scoring

In total point scoring, the net total point score of all boards played
is the score for each contestant.


Results are compared by listing the scores, MPs, and IMPs in the winneres list.

P e r f o r m a n c e :
Players like to have a general idea about their perfomance.
Matchpoint scoring has the effect, that each board shows a theoretical
maximum MP value, if only one pair has the highest score, the TOP.
This value depends on the number of cardplays documented in the traveler.
If we sum the MP-TOP values of all boards in a tournament, we may use this
value as 100 percent base for comparing.
We may now compare the total of MP won by a pair to the theoretical

It is the general belief that making 50 % auf this TOP, a pair performance is
IMP-pair scoring shows within a board traveler no theoretical IMP-TOP.
There may be a highest score, but the value of such score depends mainly from
the possibilities of a given distribution and the capacity of a pair to make a high

We may take these highest scores as born-IMP-TOPs, sum them up to a total
within a tournament and consider this as a 100 percent performance.
We may now compare the total of IMP won by a pair to the the born-TOP-MP-value.

Total-Point Tournamnent might be handled the same way as IMPs.

#TO 01                                                                                                    The Tournament Organisers might enter contractual obligation with other
entities, inclusive regional and national organisations.
Such obligations must not interfere with these laws and rules.

#TO 02                                                                                                 The TO decides the type of tournament to be played at a
certain date and time.

#TO 03                                                                                                The Tournament Organiser nominates the Tournament Director.

#TO 04                                                                                                 The TO may implement an appeals committee and set the necessary

#TO 05                                                                                                 The TO regulates the acces and presenc of spectators

The TO implements a Clubs -point system (CP). Such system should give
advantage to tournaments where fortuitousness is eliminated.
The TO should maintain an own system with the intent to establish a ranking
system for the own menbers.

The Tournament Organizer (TO) should publish Conditions of tournaments in
advance of a tournament or contest.
These should detail conditions of entry, methods of scoring, determination of
winners, breaking of ties, and the like.
The conditions must not conflict with law or regulation and shall incorporate
any information specified by the TO
They should be available to contestants.

1. by number of persons:
pair tournament; team of four persons ; individual tournament, where
pairs are formed
by two changing persons within one or more cardplays.
2. by methods of winner finding:
a) Total-point tournaments (TP), where the maximum of scores wins.
b) Matchpoin-tournaments, where having a higher score then the other
contesting pairs wins, transformed into MP (matchpoints).
c) IMP -pair tournaments, where the maximun of modified score-sums
wins.   ( also known as Butler, datum-score events).
The score of a pair is compared to the median (vugdo average) of all
Scores in a board, the difference is taken and transformed into IMPs.
d) IMP team-of four tournaments.
3. by procedures considering elimination of fortuitousness:
a) Procedures for "pair against pair" movements:
In a Mitchell tournament, players do not change compass
direction (positiv);
in a Howell tournament, all players change compass
direction (negativ).
So called"srambledMitchels" are Howell type (negativ).
b) procedures for "team of four" movements (all positiv).
Basic competition: one team plays against another team. (A versus B). The number of cardplays should be more than four .
Round Robin: a competition, where all teams play againt all other teams
and every team plays all boards.
Other: Swiss Teams , Knockout contests, and more
4. by type of deals :
using handmade deals
using random generated deals
using selected parts of random generated des
using deals of old tournaments,

The TO may establish Systems to compare results of tournaments.
Such system may employ Victory points to describe the strenght of team in
relation to other teams by IMPs won in different tournaments.

A tournament should have a minimum of eight cardplays played from both sides,
or 16 mitchell-type cardplays.
One-table tournaments need boards 1-4 played from both sides.
Players must have sufficient time to play, if necessary a play must be put to
the end of a competition.

The number of tables incorporated in a tournament should consider the abilities
of the players.
High performers, middle performers and beginners should not compete inside the
same competition.
The TO should set rules for hierarquies and the conditions for moving up or
If the number of tables is not sufficient for such division, the "stratification
system" is recommended.
To sum up results of several tournamnet, different seize (number of tables)
should be considered.

A tournament ends, when the winners list has been published, unless the
conditions of contest say otherwise.

1. An error in computing or tabulating the agreed-upon score, whether
made by a player or operator, may be corrected until the expiration of the
period specified by the Tournament Organizer. Unless the Tournament
Organizer specifies a later time, this Correction Period expires 30
minutes after the official score has been made available for inspection.
2. Regulations may provide for circumstances in which a scoring error
may be corrected after expiry of the Correction Period if the Director
and the Tournament Organizer are both satisfied beyond reasonable doubt
that the record is wrong. 

                           TD Tournament Directors Activities (TD)

The TD is responsible for the on-site technical management of
the competition. He has powers to remedy any omissions of the Tournament
Organizer.He nominates assistants.

The Director applies, and is bound by, these Laws and supplementary regulations
