By popular demand, the Bridge Bulletin will re-run the 24-part Conventional Wisdom series. Conventional Wisdom is also available online at www.acbl.org/play/conventionwisdom.html. Filling out a convention card with a partner is part of the fun of playing duplicate bridge. 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.
