Most players will find the Laws and
the Proprieties sufficient to their needs. Some, however, may wish to
adopt procedures to reduce the risk that, unintentionally, extraneous
information is given to partners, or proper information is withheld
from opponents. Possible procedures, very similar to those
successfully used in competitive bridge, are set out in
appendices 1, 2 and 3.
Note that these appendices are not part of the Laws or the Proprieties
of Rubber Bridge.
