                we have the option of passing our
              
            
            
              
                partner’s bid, or whether we must bid
              
            
            
              
                again. These articles are designed to
              
            
            
              
                increase our confidence in this area.
              
            
            
              I
            
            
              t was Ely Culbertson who first
            
            
              suggested that responder’s bid of
            
            
              a new suit at the one level should
            
            
              be forcing. That was in the 1920s.
            
            
              This has remained a fundamental
            
            
              cornerstone of our bidding ever since.
            
            
              If we open 1 and partner responds
            
            
              1 , we are expected to bid again; the
            
            
              only exception being if our partner
            
            
              passed originally, showing less than
            
            
              an opening bid.
            
            
              That’s fine, but what if we now bid
            
            
              a new suit as opener, or jump in suit,
            
            
              or jump in notrump? Are these bids
            
            
              forcing? The quick answer is no, but
            
            
              there are exceptions. So let’s take a
            
            
              closer look at opener’s rebid after
            
            
              responder bids a suit at the one level.

              A new suit by opener at the one level

              Responder has just enough to scrape
            
            
              up a 1 response to the opening bid
            
            
              of 1 ...5 high-card points plus 1
            
            
              length point for the fifth heart. When
            
            
              opener rebids 1 , continuing the
            
            
              search for a major-suit fit, responder
            
            
              doesn’t have to bid again.
            
            
              Opener’s 1 rebid covers a wide
            
            
              range of about 13–18 points. Here,
            
            
              opener has the top of that range, 17
            
            
              high-card points plus 1 length point
            
            
              for the five-card club suit. Yet game
            
            
              is well out of reach. Responder does
            
            
              well to pass and settle for partscore.
            
            
              If responder raises to 2 , opener will
            
            
              at least make a move toward game,
            
            
              and the partnership will be too high.

              than

              Opener’s second suit, diamonds, is
            
            
              lower-ranking than opener’s first suit,
            
            
              hearts. So the 2 rebid is not forcing,
            
            
              even though opener can have anywhere
            
            
              up to about 18 points. With a bare
            
            
              minimum, responder can pass and
            
            
              leave the partnership in partscore.

                should

              Here responder could pass opener’s
            
            
              2 rebid with a slight preference for
            
            
              clubs and only 7 high-card points plus
            
            
              1 length point for the five-card spade
            
            
              suit. However, experienced players
            
            
              would give ‘false preference’ back to
            
            
              2 , opener’s original suit.
            
            
              There are good reasons for this.
            
            
              First, opener has at least five hearts
            
            
              and may have only four clubs. Playing
            
            
              in a 5–2 fit should be at least as good
            
            
              as a 4–3 fit.Also, a major suit contract
            
            
              is worth more per trick than a minor
            
            
              suit contract. Most importantly, it gives
            
            
              opener another chance to bid when
            
            
              holding more than a minimum hand.
            
            
              Here opener is happy to invite game,
            
            
              and responder has enough to accept.

              When responder bids 1 , opener
            
            
              revalues the hand as 15 high-card
            
            
              points plus 3 dummy points for the
            
            
              singleton diamond. That’s too much
            
            
              for a minimum raise to 2 , so opener
            
            
              makes a jump raise to 3 , showing
            
            
              about 17–18 points.With a minimum,
            
            
              responder is free to pass.
