THE STAYMAN CONVENTION

 

 

A.    DEFINITION: ‑ The Stayman Convention is used by the partner of a 1NT or 2NT opening 

                                   bid in order to seek the possibility of a 4‑card Major suit fit.   When used in combination with Jacoby transfer bids it becomes a very useful tool in one's bidding arsenal.   It is initiated and invoked by the responder and partner of the opening NT bid by utilizing an artificial “2D” forcing call.   Stayman should not be invoked unless responder has at least an invitational strength hand; i.e., 9-10 HCP's or more. (Exception: Any hand where responder to the opening NT bid anticipates passing any feasible response by opener    Example: XXXX  XXXX  XXXX X

 

Examples:    1NT         P      “2C” (or) 2NT P   “3C”
