RESPONSE METHODS TO A 2 CLUBS OPENING
The bridge community and the bridge experts have developed, invented, originated and then modified different response methods to the strong, artificial 2 Clubs opening. It is important for the partnership to define first a destributional pattern, which falls within the requirements for such an opening and then, secondly, decide upon the continuance. It is this continuance, which is critical for relaying and communicating definitive information between two bridge players.
We present several possibilities for such responses below. They should be examined by the bridge player, by the bridge partnership, and employed until the bridge player and/or partnership feels comfortable with such method or methods.
If any bridge player would like to contribute a response method, which is not listed here, we would greatly appreciate this contribution, so that other bridge players can benefit from this information.
Albarran - De Nexon Responses - This concept was introduced and devised by Mr. Pierre Albarran and Mr. Baron Robert de Nexon of France and authors of the bridge book: Notre Methode de Bridge, published 1935. This treatment and/or convention is used only after a 2 Clubs opening by the responder. Fundamentally, the Albarran - De Nexon convention is Ace Showing, providing information to the 2 Club bidder before he/she has a chance to define and describe his/her holding.Ace Showing Responses - These are responses to forcing strong artificial Two Clubs opening bids that are based on the theory that the opener with a powerful unbalanced or semi-balanced hand is more interested in the first-round controls of his partner than in his long suit or general strength.
Automatic Two Diamonds Response - A treatment devised by several partnerships, whereby the only response permitted to a strong artificial Two Clubs opening must be 2 Diamonds.
CAB Responses - The C.A.B. responses to a strong, articial 2 Clubs opening is a feature of the C.A.B. Bidding System devised by Mr. Leslie William Dodds of London, England. These responses are also part of the Acol Bidding System generally employed in England and Australia with minor differentiations.
Control Showing Responses - This conventional method is a derivation of several bidding systems developed and defined by bridge experts from Italy. The intention is to immediately show with the first response the number of Aces and Kings contained in the hand of the responder. This particular conventional method is sometimes referred to as Step Responses.
Danish Control Showing Responses - The original concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the variation and/or version as suggested by Mr. Lars Blakset and Mr. Soren Christiansen of Denmark.
Edgar Kaplan Control Showing Responses - The original concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the variation and/or version as suggested by Mr. Edgar Kaplan.
George Rosenkranz Control Showing Responses - The original concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the variation and/or version as suggested by Mr. George Rosenkranz, which not only show the number of controls but also possible stoppers in suits for a suitable No Trump contract.
New South Wales Control Responses - The original concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the responses provided by the Australian System designated as New South Wales, and which is a variant of the Vienna System, devised and developed by Mr. Richard Cummings and Mr. Tim Seres and other Australians.
Oswald Jacoby Step Responses - The original concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the variation and/or version as suggested by Mr. Oswald Jacoby.
Eric Kokish's Responses to a Strong, Artificial 2 Clubs Opening - Mr. Eric Kokish believes that most experts are correct in the opinion, that two-suited hands should not be opened with the artificial, strong 2 Clubs bid. Therefore, when the 2 Clubs opener shows a second suit, it is expected to be a 4-card suit. This stipulation affects some of the recommended sequences.
Gamma Responses - These responses to a Strong, Artificial 2 Clubs opening were developed by Dr. E. Lachand of France. He also devised the Gamma System, which features a 2 Clubs opening bid being employed with two different holdings.
Two Diamonds Negative Response - A response showing minimum values to an opening forcing 2 Clubs bid.
Two Diamonds Positive Response - A partnership agreement, whereby the only possible positive response is 2 Diamonds after an opening of a strong artificial 2 Clubs bid.
2 Diamonds As Negative And 2 Hearts as Neutral Response - Two different responses to a strong artificial Two Clubs opening.
Two Hearts Negative Response - Among the many and various responses to a strong, artificial 2 Clubs opening are the following first responses to let the opener know a possible distribution and a possible number of values held by the responder.
Cheaper Minor as a Second Negative - A treatment allowing the responder to show with his rebid the lower range of his values.
Herbert Second Negative Response - A convention to show the lower range of a weak response used by the responder on the second rebid.
Martelsby Responses - The basic concept is designated as Control Showing Responses (also Step Responses) to a Strong, Artificial 2 Clubs opening. These original responses should be viewed first and then the variation and/or version as suggested by Mr. Charles (Chip) U. Martel of Davis, California, and Mr. Lewis (Lew) Stansby of Castro Valley, California. Their version combines not only the opportunity to show the number of controls held by partner after a strong, artificial 2 Clubs opening, but also the actual suit, in which the controls are located.
Natural Responses - The origin of these responses is unknown. This conventional method, employed in responding to a strong, artificial 2 Clubs opening by partner, is completely natural except for the first response of 2 Diamonds, which is artificial and negative. As a result, all other responses by partner are natural and positive.
Five-Five Natural Responses - 5-5 Responses - The origin of these responses is unknown. This version of the Natural Responses method follows the basic outline of the original concept, but has one specific requirement for all suit bids by the responder.
Marshall Miles Version of Natural Responses - Mr. Marshall Miles of California proposed an altered version of the original concept of Natural Responses by reversing the bids so that they also reflect a certain amount of values, thereby communicating to partner a minimum amount of points in the suit bid plus the required length of the suit bid.
Super Sudhaker - This conventional method has been developed, contributed and presented with his express permission by Mr. Sudhakar Bhatt. It is a conventional method of responding to a strong, artificial 2 Clubs opening whereby the responder may or may not be a passed hand. The concept has borrowed elements of other conventional methods, with which it has several similarities, but contains certain requirements for the responder which differ and excludes the first response of a 2 No Trump bid.
