PAIR EVENTS - GENERAL CONDITIONS OF CONTEST
These Conditions of Contest may not be changed
at any level of play
during the course of this event.
Lack of knowledge does not constitute cause for
exemption.
These conditions apply to all pair events. At
the North American
Bridge Championships, there may be additional
specific conditions. In
such cases the specific conditions will
supersede the general ones.
These conditions must be posted. Sponsoring
organizations may amend
these conditions for specific events but such
amendments must appear
in all printed tournament schedules.
Furthermore they must be posted
prior to the start of event.
Sponsoring organizations may, with ACBL
approval only, amend these
conditions for a specific event.
The final decision on any item in these
conditions shall be made by
the Director-in-Charge. Furthermore, any issue
not specifically
covered will be resolved by the
Director-in-Charge.
ENTRY AND PARTICIPATION
1. Each partnership will consist of two
players. In events which have
a masterpoint restriction the partnership's
entry will be based on
the player with the higher masterpoint
holding. However, Life
Master events require that both members of a
pair be ACBL Life
Masters or its equivalent.
2. Each player must play at least seventy
percent of the boards,
played by the partnership to be eligible for
either session or
overall masterpoint awards.
PLAY
1. Sponsoring organizations must announce in
advance the type of
event scheduled. Options include open, Life
Master, events
restricted by either an upper or lower
masterpoint limitation,
flighted, stratified or strati-flighted. In
addition each event
may be segregated by requiring pairs to be
both men, both women or
mixed (i.e one man and one woman).
In flighted events groups are segregated by
masterpoint totals
(i.e A is Open, B is restricted to players
with less than 1000
MP's and C for players with less than 300
MP's).
In stratified events the three groups play
together but are ranked
both collectively and separately (i.e a C
player can win points by
ranking in A, B or C).
In strati-flighted events at least one
group is segregated and
another stratified (i.e A is Open, B is
stratified with the top
group 300 - 1000 and the second group 0 -
300).

2. Events may be run from one to six sessions
and may have cuts in
the size of the field after specified
sessions. Consolation events
may be run concurrently with the final
session(s) at the
discretion of the Sponsoring Organization.
3. A Side Game Series (Continuous Pairs) may be
run at sectionals or
regionals. There must be at least three
sessions. Individual
sessions may be stratified and give overall
and section awards
based on side game rating. Players compete
as individuals and
overall placing will be determined by the
player with the best sum
of percentages of his two best sessions. Any
player still entered
in another championship event (such as a
sitout in a Knockout or a
player who has withdrawn from another event)
may play in the Side
Game Series (Continuous Pairs) but that
session will not count
towards his overall ranking nor will gold
points be awarded for a
section top at regionals or NABCs.
4. Management, at it's discretion, may
authorize barometer scoring
with publication of previous rounds' results
during a session for
any matchpoint event for which ACBL is the
sponsoring
organization. The present IMP pairs event
may not be run using
barometer scoring if the results are made
public during the
session.
5. A partnership is responsible for knowing
when their methods apply
in probable (to be expected) auctions. A
pair may be entitled to
redress if their opponents did not
originally have a clear
understanding of when and how to use a
convention that was
employed.
CONVENTIONS
The ACBL General Convention Chart will govern
bidding and playing
methods unless the Sponsoring Organization has
announced in writing to
the contrary.
SEEDING
Every effort should be made to seed all
sections of the field in both
directions. In general, each pair should play
against the same
strength field each session. (Note: This is
usually accomplished by
making random adjustments in the starting
position of one of the
seeded fields each session.) While the
Sponsoring Organization may
provide assistance the final decision in all
matters relating to
seeding the event will rest with the
Director-in-Charge.
QUALIFYING EVENTS AND CONSOLATIONS
1. Events of two or more sessions may be run as
some number of
qualifying sessions and some number of final
sessions. Consolation
events may be scheduled for non-qualifiers
at the discretion of
the Sponsoring Organization. Conditions
regarding the number of
pairs to be qualified must be announced as
early as possible
during the qualifying session(s).

2. In order for a partnership to qualify for
the finals both members
must be present. If not an alternate
qualifier will be selected.
From among available pairs the one with the
highest score in the
qualifying session(s) will be selected.
3. A carryover will be calculated based on
scores in the qualifying
session(s). The maximum spread between
highest and lowest
carryover will be equal to the number of
sessions in the events
times top in the final session(s). For six
session events with two
cuts, the maximum spread for the middle two
rounds will be only
two and one half times top in the semi-final
sessions.
4. Carryovers will be based on the following
formula -
C = (M - m) [ (Q/E)(AxBxQ)/S)] where
C =
carryover
B = number of boards played in qualifying
session(s)
S = sum of the scores of all qualifiers
M = matchpoints of a given pair
m = matchpoints of lowest qualifying pair
E = pairs entered in the event
Q = pairs to be qualified
A = average on each board in the final
session(s)
If the formula determines the high carryover to
be above the allowable
limits then the formula is abandoned and the
following procedure is
followed. Subtract the low qualifying score
from the high qualifying
score and divide this number into the maximum
allowable carryover.
The resulting factor is multiplied by the
difference of a score and
the low qualifying score. Thus the low
qualifier will have a
carryover of zero and the high qualifier will
have the maximum
allowable carryover.
5. Ties for the final qualifying position will
be broken as follows:
a. Considering only boards played in common,
a pair will receive
one point for each board played in common
on which it outscores
the other tied pair(s) and one half point
for each tied board.
In addition on boards not played in
common a pair will receive
one point for a score above average and
one half point for a
score of average.
b. If the above does not break the tie or in
cases where the pairs
played no boards in common, compare
matchpoints on all boards
against average. Award a pair one for
each score above average
and one half for each score of average.

TARDINESS & SUBSTITUTIONS
1. Substitutes are subject to the discretion of
the Director-in-
Charge or his designee and may not
appreciably strengthen the
partnership.
2. A qualified pair which fails to seat both
members of the
partnership ten minutes after the announced
starting time of a
finals will be replaced by the highest
available alternate
qualifier.
CORRECTION AND APPEAL PERIODS
1. The score correction period for player
errors expires at the
completion of play of the session following
the one in which the
error occurred.
2. For director errors the correction period
expires twenty four
hours after the completion of the event or
thirty minutes after
completion of the last event of the
tournament, whichever is
earlier.
3. For qualifying events the score correction
period for both player
and director errors expires one hour before
the announced starting
time of the first final session.
4. The appeal period of or for a Director's
ruling expires one half
hour after the completion of a session or
the starting time of the
next session whichever is earlier. |
