Filling Out the Convention Card
Edited by Bon A. Liu

Whether you prefer a simple approach or a system with lots of bells and whistles, the convention card is a great 
way to keep you and your partner on the same wavelength.

Many clubs require both members of a partnership to have completed convention cards available as a courtesy 
to the opponents. Your convention card allows other players to get an overview of your methods at a glance.

The series ("Conventional Wisdom") will focus on assisting new players (and even some experienced ones!) 
with the proper use of the ACBL convention card.

The purpose of the convention card

Although the convention card is a great way for you and your partner to discuss your methods and refresh your
 memories as to what your agreements are if you haven't played together in awhile, remember that the 
convention card exists for "the convenience of your opponents". 

The opponents may wish to look at your card at the beginning of a round to get a general idea of what your
 methods are,they might want to see what your opening lead agreements are when they declare or they 
may wish to look at your card during the auction to see what your agreements are without asking you to 
explain them verbally.

Note: Just as you should ask questions during the auction only when it is your turn, you should look at an 
opponent’s card only when it is your turn to bid.

Properly filled out cards
We're all encountered pairs who have either no convention cards or blank cards with the words standard?scribbled at the top. This is inappropriate and not in the spirit of the game. If you haven't got time to properly fill out the convention card, you haven't got time to play. It is also required that both partners ?not just one 
to have properly filled-out cards. 

Both players must have identically filled-out convention cards. It is not permitted for one partner to make calls that mean one thing while the same call from his or her partner means something else.

PART I-General & Open

PART II-Overcalls

PART III-Signals & Double

Notes

All In One

Looking at your own convention card during the auction or play?
No
The Laws forbid access to written memory aids during any phase of the game, and this includes your own 
convention card. Your convention cards are for the opponents’ use,not yours. 

Note that clubs may relax this rule, however,especially if new players are participating, to assist them in 
learning. Experienced players may wish to overlook a newcomer’s dependence on the card. 

All players should be aware, however, that the card is not a memory crutch:

newcomers may be given a pass, but others should refrain from peeking at the card during the bidding or play.

Active ethics
Be proactive in making sure your opponents understand your explanations. Don't use jargon or convention 
names when explaining calls. If a opponent looks confused at your explanation, rephrase. Keep your 
explanations simple, direct and open ?the same way that your methods should appear on your convention card.
