If you are playing in a NZB tournament you and your partner will be asked to fill in a system card. You can do this prior to the event and take it with you. The role of the system card is so that all systems and partnership agreements are transparent, and can be asked for by the Director if there is any confusion or irregularity.
If you would like more information on system cards or to access an editable template please click on this NZB system cards link. It will take you directly to the main NZB website.
