Please don’t forget to alert and announce when appropriate:

• Alert any bid which is not natural or has an unexpected meaning (unless the bid is announceable)
• Alert or announce only your partner’s call, never your own (unlike BBO)
• You either alert or announce, but not both in the same time
• You don’t need to alert/announce any bids above 3NT after the 1st round of the auction
• If you are asked for the meaning of partner’s call and you are not sure, you must not say how you intend to interpret it.
