The Stayman convention is a standard response to a natural 1NT or 2NT opening, developed by Samuel Stayman in 1945. In its most basic form, it is an asking bid, asking partner to bid a 4-card major suit or 2 ♦.When to use Stayman in a four card game?
Typically Stayman is used on hands of 11+ points when responder has a four card major and game might be possible if there is a major suit fit. Stayman can also be used on any hand of zero to 28 points when it would be useful to find out if partner has a 4 card major.How is a non-forcing Stayman different from a forced Stayman?
In the forcing Stayman variant, the bid is one-round forcing. In the original Precision Club system, forcing and non-forcing Stayman are differentiated in the start: 2 ♣ by responder shows only invitational values (and the continuation is the same as in basic Stayman), while 2 ♦ is forcing to game (responder bids 2NT without majors).When to use the Stayman convention in contract bridge?
Stayman is a bidding convention in the card game contract bridge. It is used by a partnership to find a 4-4 or 5-3 trump fit in a major suit after making a one notrump (1NT) opening bid and it has been adapted for use after a 2NT opening, a 1NT overcall, and many other natural notrump bids.
