HOW RESPONDER COMPETE          After a opening in first or second position if opponent interfere there some standards bids in 2/1 system where Responder may inform his hand to Opener and here we will discuss these Reponder's bids: PART 1/3 - HAVING LESS THAN 10 HCP 1- Suppose Responder has: xx xx AQJ10xx J10x and bidding goes: a) Opener Overcaller Responder        1         1            3 <= less than 10 hcp and good 6 cards b) Opener Overcaller Responder        1         2            3 <= less than 10 hcp and good 6 cards c) Opener Overcaller Responder        1        double     2 <= no redouble, less than 10 hcp, transfer to 2 d) Opener Overcaller Responder        1        double     2 <= no redouble, less than 10 hcp, transfer to 2 e) Opener Overcaller Responder        1         2           double <= 4+4+ or 7-9 hcp and 6 or 6 cards         ?       2nt        pass          3 <= sign-off        3        pass          3 <= sign-off        3        pass          pass        3        3             4 <= sign-off             3        pass          pass f)  Opener Overcaller Responder       1         2            double <= 4+4+ or 7-9 hcp and 6 or 6 cards         ?       2        pass          3 <= sign-off      2nt        pass          3 <= sign-off       3        pass          3 <= sign-off       3        pass          pass       3        3              4 <= sign-off -------------------------------------------------------------------------------- 2- Suppose Responder has: xx AQJ10xx x J10x and bidding goes:  g) Opener Opponent Responder Overcaller      1         pass         1nt             2      pass      pass         3 <= invitation to 4 h) Opener Overcaller Responder Opponent      1          2/2      double*      3/3 <= support     pass        pass         3 <= sign-off       * means less than 10 hcp i) Opener Overcaller Responder Opponent      1          2/2      double        pass     pass        pass         3 <= invitation to 4 (if 2 then sign-off) --------------------------------------------------------------------------------- 3- Suppose Responder has: xx KQJxxx x J10xx and bidding goes:  j) Opener Opponent Responder Overcaller      1         pass         1nt             2      pass      pass         2 <= sign-off k) Opener Opponent Responder Overcaller      1         pass         1nt             3      pass      pass         3 <= sign-off ============================================== PART 2/3 - HAVING 10-11 HCP When Responder has support to Opener's major after the interference the priority is inform partner about invitation hand with 10-11 hcp. Not necessaraly bid another suit and after support partner because this may confuse Opener: It seems Slam interesting or 2 cards support? So the cuebid is the apropriat way to inform the invitation. 4)  Suppose Responder has: 10xx AQJ10x xx K10x and bidding goes: l) Opener Overcaller Responder        1         2            3 <= 3 cards support 10-11 hcp         ?        3 <= minimum oprning 12-13 hcp - Responder should pass       3nt <= strong opening 18-19 hcp - Responder may pass        4 <= asking for cuebid - Responder may cuebid 4        4 <= good opening 14+ hcp - Responder must pass m) Opener Overcaller Responder        1       1             2 <= 5+ and 10+ hcp one-round force         ?       2nt      pass          pass        3      pass          pass <= without support game is difficult        3      pass          pass <= maybe a misfit hand        3      pass          pass <= Opener has minimum hand        3      pass          4    <= Opener splinter shows Slam interesting        4      pass          pass <= Opener has good hand n) Opener Overcaller Responder        1      2             3 or double <= difficult decision but double is         ?                                                    the correct bid to avoid overbid       2nt     pass         pass        3     pass         pass        3     pass           3        3     pass           4        4     pass          pass =============================================== PART 3/3 - HAVING 12+ HCP When partner opens and opponent interfere making Responder's bid be at level 2 or 3 if Responder double this shows 8-11 hcp but if Responder bids then this must be GF with 12+ hcp. In case Responder double to show 4 cards in the other major and after cuebid this is GF. 5)  Suppose Responder has: 10x AKJ10x xx KQ10x and bidding goes: o) Opener Overcaller Responder        1         3            3 <= GF 5+ denies 3 cards         ?        3                 =>   4       3nt                 =>  pass        4                 =>   5        4                 =>   4        4                 =>  pass p) Opener Overcaller Responder Advancer        1        1             2             3       pass     pass          4  <= not GF because there are 2 Spades losers         ?       pass <= also 2 Spades losers        4   <= Qx or xxx with minimum        5   <= singleton Spades with minimum 5+ cards and control 6)  Suppose Responder has: x AKJx Kxx KQ10xx and bidding goes: q) Opener Overcaller Responder Advancer        1        2            double       3       pass     pass          4  <= GF singleton Spades or Ace/void         ?       4nt <= need 2 aces to try Slam        5 <= only one ace r) Opener Overcaller Responder Advancer        1       1            double       2        3      pass          3  <= GF singleton Spades or Ace/void         ?       4      <= need 2 aces to cuebid so Responder should bid 4nt                       and using rkc1430 if Opener response is 5 then 6                       and if response is 5 (no Queen) then pass       4      <= only one ace minimum so Responder should pass        ==============================================
