|
A. |
Right to Choose
Call or Play |
|
A player may make any call or play (including an intentionally
misleading call such as a psychic bid or a call or play
that departs from commonly accepted, or previously announced, use
of a convention), without prior announcement, provided that such call
or play is not based on a partnership understanding. |
|
|
B. |
Concealed Partnership
Understandings Prohibited |
|
A player may not make a call or play based on a special
partnership understanding unless an opposing pair may reasonably be
expected to understand its meaning, or unless his side discloses the
use of such call or play in accordance with the regulations of the
sponsoring organisation. |
|
|
C. |
Directors
Option |
|
If the Director decides that a side has been damaged
through its opponents failure to explain the full meaning of
a call or play, he may award an adjusted score. |
|
|
D. |
Regulation of
Conventions |
|
The sponsoring organisation may regulate the use of
bidding or play conventions. Zonal organisations may, in addition,
regulate partnership understandings (even if not conventional) that
permit the partnerships initial actions at the one level to
be made with a hand of a King or more below average strength. Zonal
organisations may delegate this responsibility. |
|
|
E. |
Convention Card |
|
1. |
Right to Prescribe |
|
|
The sponsoring organisation may prescribe a convention
card on which partners are to list their conventions and other agreements
and may establish regulations for its use, including a requirement
that both members of a partnership employ the same system (such a
regulation must not restrict style and judgement, only method). |
|
|
|
|
2. |
Referring to Opponents Convention
Card |
|
|
During the auction and play, any player except dummy
may refer to his opponents convention card at his own turn to
call or play, but not to his own (12). |
|
|
|
(12) A player
is not entitled, during the auction and play periods, to any aids
to his memory, calculation or technique. However, sponsoring organisations
may designate unusual methods and allow written defences against opponents'
unusual methods to be referred to at the table. |
