Bidding Changes


The EBU has introduced several new regulations for the running of EBU events from 1 August,2006. The club committee has decided to adopt these changes as we need to have conformity with other clubs and competitions.


The changes are intended to help players understand their opponents’ bidding without having to ask.  Previously, asking about a bid when you did not expect to bid yourself was frowned upon as it could pass information to your partner.  But please note – conventions cards are still needed.


The club will introduce one new idea at a time.  For those who want to know more there are articles in bridge magazines and a summary is also available on the club notice board.


In each section the rules which apply to most of us are in black.  You only need to study the rules in red if you have a complicated system.





1.One no trump opening bid and subsequent bids


Your partner bids 1 NT.  All you have to do is announce its strength!  E.g. “twelve to fourteen”.  You announce this as soon as your partner bids, before the opponents make their next call.  If you don’t announce it, the opponents are entitled to ask you what the strength is.


If your 1 NT opening may include a singleton you should also announce this: “twelve to fourteen, may include a singleton”.  You do not need to explain any other details.

2. Stayman where there has been no intervention by the opposition.


After you open 1NT, your partner responds 2 clubs. If this is Stayman you should announce “Stayman” instead of alerting. Your partner does not need to alert your 2 diamond response.


If your partnership agreement has responses to Stayman which are not the usual ones, Stayman should be alerted and details should be on your convention card.


If there is no announcement or alert, this would mean that 2 clubs is natural. 


3. Transfers where there has been no intervention by the opposition.


If your partner responds 2 diamonds or 2 hearts to your 1 NT opening bid, requiring you to transfer to hearts or spades, you should announce “hearts” or “spades” respectively. 


If you have an agreement whereby the transfer bid does not guarantee 5 cards in the intended suit, then the transfer should be alerted.


If 2 diamonds or 2 hearts are not announced or alerted, they are assumed to be weak take-outs.


4. 2 level opening bids

When partner makes a natural opening bid at the 2 level:

You should announce the strength of his bid:

1.     “Strong, forcing”

2.     “Strong, not forcing”

3.     “Intermediate” i.e. normal opening strength

4.      “Weak”

Bids which are not natural should be alerted: e.g. the Acol 2 clubs.







1. Doubles

The following doubles do not need to be alerted:

     of natural bids (assumed to be for take-out)

     of 1 NT (assumed to be for penalties)

     of artificial bids (assumed to be for penalties i.e. to indicate a                                                                                                             holding in the artificial suit)

All other doubles need alerting.


2. Short minor suit opening bids – only alertable if they may contain less than 3 cards in the suit.


3. Calls above 3 NT:

Most bids over 3 NT no longer need alerting – this includes Gerber and the responses to it.


Bids over 3 NT which need to be alerted:

1.     Opening bids if they show a different suit to the one being bid.

2.      Doubles and redoubles if they show a different suit to the one being doubled (or redoubled).
