Each player is required to have a convention card – filled out legibly and on the table throughout a session. The convention card must include the first and last name of each member of the partnership, and the cards must be identical.
If a director determines that neither player has a substantially completed card, the partnership may play only the Standard American Yellow Card and may use only standard carding. This restriction may be lifted only at the beginning of a subsequent round and approved by the director. Further, the partnership will receive a 1/6-board matchpoint penalty for each board played, beginning with the next round and continuing until the restriction is lifted. In IMP team games, penalties shall be at the discretion of the director.
If the director determines the partnership has at least one substantially completed convention card but has not fully complied with ACBL regulations the director may give warnings or assign such penalties as he/she deems to be appropriate under the circumstances.
