1NT WITH 5 CARDS MAJOR   

This adapted 1nt opening use Barrelled Stayman conventions also know as Two Way Stayman where 2 is a Stayman not forcing and 2 is game force. This convention is mostly used with weak 1nt 13-15 hcp but may also be used with strong nt opening. Lets assume that our 1nt opening is 15-17 hcp and the allowed distribution are: 4333, 4432, 5332 so it is not recommended the open of 1nt with 5422. The advantage of this convention is allow the opening of 1nt with 5 cards major and also know when Opener has a 5 card minor. The drawback in this convention is not use transfers at level 2 to make the strong hand be the declarer.  Opener Responder (action without interference)   1nt       pass <= 7 or less hcp (exclude 6/7 cards suit)                  2 <= Barreleed Stayman - not forcing asks for major                        Opener bids:                        2 <= no major;                        2 <= 4/5 cards in Hearts - can also have 4 cards;                        2 <= 4/5 cards deneis 4                        Responder can pass in 2 or he bids sign-off in 2 or 2                  2 <= Barreleed Stayman Game Force (GF) with 10+ hcp                         Opener bids:                         2 <= 4 cards and may have 4 cards;                         2 <= 4 cards;                        2ST <= 4 + 4 have both minors                                3 by Responder asks distribution                                Opener bids:                                3 => 2+3+4+4 or                                3 = 3+3+4+4                                       Responder decide: 3ST / 5 in a minor / try Slam                         3 <= 5 cards                         3 <= 5 cards                         3 <= 5 cards                         3 <= 5 cards                       3ST <= 4333 distribution with one minor suit              2 <= to play - sign-off (there are no transfer)              2 <= to play - sign-off             2nt <= invitation to 3ST showing 8-9 hcp              3 <= 5-4 with 10-14 hcp in 5431 distribution                         Opener bids:                         3 relay asking for the singleton                              Responder bids up the line:                              3 => singleton                              3 => singleton                              4 => singleton with 6421 max 5+ controls                              4 => singleton with 6421 max 5+ controls                              4 => singleton with 5521 max 5+ controls                              4 => singleton with 5521 max 5+ controls                         3nt to play - good stoppers in majors                   3 <= 5-4 with 10-14 hcp in 5431 distribution                         Opener bids:                         3 relay asking for the singleton                              Responder bids up the line:                              3 => singleton                             3nt => singleton                              4 => singleton with 6421 max 5+ controls                              4 => singleton with 6421 max 5+ controls                              4 => singleton with 5521 max 5+ controls                              4 => singleton with 5521 max 5+ controls                          3nt to play - good stoppers in majors                   3 <= 5 cards and asks for support -                         Opener bids 3nt with 2                         Opener bids 4 without a top honor or minimum 15 hcp                         Opener cuebid (3/4/4) with a top honor and 16-17 hcp              3 <= 5 cards and asks for support -                         Opener bids 3nt with 2                         Opener bids 4 without a top honor or minimum 15 hcp                         Opener cuebid (4/4/4) with a top honor and 16-17 hcp            3nt <= to play                        Responder may continue bidding his singleton with specials                        distribution 6-4 bidding 4 or 4 or in 5-5 bidding 4 or 4              4 <= Gerber - asks for aces (4=0/4; 4=1; 4=2; 4nt=3)              4 <= 6+ cards Transfer for 4 sign-off              4 <= 6+ cards Transfer for 4 sign-off              4 <= 6+ cards Transfer for 5 sign-off              5 <= 6+ cards Transfer for 5 sign-off            4nt <= quantitative - invitation to 6nt with maximum            5nt <= quantitative - invitation to 7nt with maximum                          maximum means 17 hcp or 16 hcp with 5332                         with 4333 distribution 17 hcp is minimum In case of interference the partnership need a convention to establish when Responder bids sign-off or is trying to find fit in a major for game. Suggestion Lebensohl.  After a 1nt opening and a penalty double we may use: pass => nothing to do but Opener having a 5 cards suit must bid it redouble => asks for Opener bid 2 and that may be corrected to 2 2 => Stayman - shows both majors 2 => transfer to 2 2 => transfer to 2 / / /
