MULTI TWO DIAMONDS

Variation of Multi 2 Diamonds by Mr. Barry Rigal and Dr. Chris Ryall

Another method of responding has been suggested by Mr. Barry Rigal and Mr. Chris Ryall of England. This method can be viewed on the website of Dr. Chris Ryall. It is also the recommendation of Mr. Barry Rigal and Dr. Chris Ryall that the individual partnership must discuss what to do over opponents doubles and overcalls. The premise of this method is that the opener have one of the following holdings:

Poor Weak Twos in the Major suits
Sound Weak Twos in the Major suits, 8-9 high card points
Sound Weak Twos with a side suit splinter
Sound Weak Twos, balanced with a fluently running suit
A strong (e.g. 22-24) balanced hand with 22-24 high card points
A pure Acol Two in a Minor suit

The problem, as noticed by Mr. Barry Rigal and Dr. Chris Ryall, was that there appears to be insufficient bidding space on the levels available after a Multi 2 Diamonds opening to reach the optimal contract, especially if that contract should be 3 No Trump. Using this method, which specifically states that a Multi 2 Diamonds opening should be:

2 :

Shows 5-9 high card points by favorable vulnerability.

2 :

Shows 7-11 high card points by unfavorable vulnerability.

The concept behind the method, in the case that a contract of 3 No Trump is the optional contract, is to ignore the Major suits and to employ a Two-Way 3 Diamonds response to 2 No Trump. Other response include:

* A Paradox bid is a call of the suit you do not hold when the length in one of two suits has been shown or implied by partner's bid, generally when the partnership expects to establish the final contract in one of these suits.

The partner can simply bid the lower suit for the partner to either pass or correct. Alternatively, if the partner has a fit for that lower suit, the partner bids the other suit. Therein lies the paradox. Although a call of the lower suit with support for the higher may also be paradoxical, this case is trivial. Using a Paradox bid generally forces the partnership one level higher, but this is accomplished only with a good fit. Two examples follow:

It is apparent that the opponents have game. But a Paradoxical Preempt of 3 makes and also is totally obstructive for the opponents to reach their contract successfully.

Play in 3, or in 4.

If you wish to include this feature, or any other feature, of the game of bridge in your partnership agreement, then please make certain that the concept is understood by both partners. Be aware whether or not the feature is alertable or not and whether an announcement should or must be made. Check with the governing body and/or the bridge district and/or the bridge unit prior to the game to establish the guidelines applied. Please include the particular feature on your convention card in order that your opponents are also aware of this feature during the bidding process, since this information must be made known to them according to the Laws of Duplicate Contract Bridge. We do not always include the procedure regarding Alerts and/or Announcements, since these regulations are changed and revised during time by the governing body. It is our intention only to present the information as concisely and as accurately as possible.
