====Asking Bids==== We use only two three of the asking bids; Alpha, Gamma and a control ask. |Alpha:|Where the 1\C bidder makes the asking bid introduces a new suit; his partner's response is tied to his holding in this suit and also on his controls.| |Gamma:|Where the 1\C bidder supports his partner's suit and asks for details of partner's holding in the suit. We only treat 2\H, 2\S, 3\C, and 3\D as Gamma bids. | |Control ask:|When responder can show his suit at the 1-level, a 1N rebid by opener asks for controls.| ===The Alpha bid=== Whenever the 1\C opener bids a suit of his own after a positive response, he asks about partner's holding in this suit; at the same time partner gives information about his controls. Suppose the bidding begins 1\C - 1\H - 1\S; 1\S is Alpha and asks for responses as follows: |1st step (1N)|no positive support for \ss (less than \sHxx or \sxxxx) and not more than 3 controls | |2nd step (2\C)|no positive support for \ss, but upwards of 4 controls| |3rd step (2\D)|positive support (\sHxx, \sxxxx, or better), but not more than 3 controls| |4th step (2\H)|positive support, upwards of 4 controls| |5th step (2\S)| 4-card positive support (\sHxxx or better) upwards of 4 controls| The 6th and higher steps are defined in one of two ways: - If responder has shown a balanced hand of 7 to 12 or 15 up, then the 6th step shows no fit with 15+ HCP and the 7th shows a fit with 15+ HCP. Neither response promises or denies a specific number of controls. - If responder has shown a suit, then the 6th and higher steps are natural, deny as many as 4 controls and show a singleton or void in opener's suit. The 5\+-5\+ responding hand will have 6\+ losers if a jump is made. With 5 losers or fewer, bid the first step (no fit, 3 controls or fewer). Agreed --- //[[John@Kinn.Org|John Kinn]] 2017/05/18 15:46// In general after receiving a response showing positive support, opener will either bid a new suit (presumably a natural slam try), or bids responder's suit to show a fit. In the case of bidding responder's suit, the bid acts as a Gamma bid (see Gamma asking bid ) if and only if the bid is 2\H, 2\S, 3\C or 3\D. However after receiving a response showing positive support for a minor when responder has shown a 7-12 HCP balanced hand, we change our approach. In order to "switch suits" into a possible major suit fit, bids of 3 major are an attempt to find a 4-4 fit in that major. In order to initiate N or slam tries with the minor suit agreed, it is necessary for opener to bid 3 minor. If he bids 3 of the agreed minor, he doesn't show or deny anything in particular about his suit, but there are negative inferences to be drawn about his holding in the other minor. Examples: |\SAKxx|\Sxx| |\hAQ|\HKxxx| |\DQx|\DAJxx| |\CQJ10xx|\CAxx | |--------------------------------------------------------------------------------|| |1\C|1\S| |2\C|2N (fit with 4+ controls)| |3\S (\s suit)|3N (no \S fit) | |?| |--------------------------------------------------------------------------------|| |\SAKx|\Sxx| |\hAQx|\HKxxx| |\DQx|\DAJxx| |\CQJ10xx|\CAxx| |-----------------------------------------------------------------------------|| |1\C|1\S| |2\C|2N (fit with 4+ controls)| |3\C (probably no control of \d)|3\D| |3N|4\H| |4\S|? | ===The Gamma bid=== This asking bid occurs when opener supports his partner's suit. This initiates inquiry about the suit, to which responder answers as follows: |1st step|no top honors (an honor is the A, K, or Q)| |2nd step|5-card suit headed by one honor| |3rd step|5-card suit headed by two honors| |4th step|6-card suit headed by one honor| |5th step|6-card suit headed by two honors| |6th step|three top honors| ===The control ask=== We no longer play control ask, 1NT is natural in the sequences below, and so are responses to it. ** OBSOLETE - BEGIN ** In forcing auctions that begin with opener bidding 1N as his first natural bid after a positive natural bid by responder, the 1N bid asks for controls: ^Responder's Bid^Controls shown^ |2\C| 0 - 2 | |2\D| 3 | |2\H| 4 | |2\S| 5 | |2N|6 or more| -------------------------------------------------------------------------------- Higher responses by responder are natural and show 5-5 or better. It is not clear how many controls he has.
