Variation of a Defense Concept

Contributed by Mr. Andrei Varlan, to whom we owe a debt of gratitude. *MS March 2003*. The photograph below shows Mr. Gilles Quéran from the year 2008 and can be found on his website.

     

This is a defense mechanism against a 1 No Trump opening by an opponent, which was proposed and expounded by bridge experts and bridge teachers Mr. Gilles Quéran from Angers, France, and Mr. Andrei Varlan, who lives in Gréoux-Les-Bains, south of France, but originally from Romania.

The development of this variation of a defense concept is based on an excerpt of the publication: The Encyclopedia of Pairs Tournaments, translated to French by Mr. Michel Lebel in the late 1980s and written by Mr. Kit Woolsey in 1979, but which was never developed further and had not been designated. The concept itself is based on an idea of Mr. Jean-René Vernes of France.

Note: The following is a description of this defense mechanism after a player has opened the auction with 1 No Trump. The partner of the No Trump bidder passes throughout all following bidding sequences. By interference from the partner of the No Trump bidder the calls and bids of the advancer and intervenor may change according to partnership agreement.

Opener Overcaller Partner Advancer Meaning
1 NT Double Pass Shows a one-suited holding; generally an unknown Minor suit.
Pass This is a Penalty Pass. Shows sufficient values for a defeat of the contract but not game values.
2 Relay bid asking partner to bid his suit.
2 / If the suit is a Major suit, then this promises a very strong holding. Possibly game-forcing.
1 NT 2 This is the Landy conventional defense method.
1 NT 2 Promises a 6-card suit in one of the Major suits.
2 Relay bid asking partner to bid Spades if the suit is Spades and to pass if Hearts is the suit. This relay bid does not indicate or promise any values.

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.
