- REVERSES NOT-SO-FORCING
-
-
- After a one-over-one response in "standard" bidding, reverses are
- not only forcing but also promise another bid. And if the reverser
- then raises responder's suit, that's forcing too! To avoid getting
- too high when responder is very weak, opener must resort to less
- descriptive rebids with only 16-17 HCP. After opening 1D with S-3
- H-AJ32 D-AK873 C-A62, we are told that the "expert" rebid after a
- 1S response is 2C. Yuk! Such sequences often lead to a bad
- contract. Is partner supposed to bid again with S-J8762 H-K854 D-6
- C-Q83? And what if opener's minor suits are reversed (S-3 H-AJ32
- D-A62 C-AK873)? Go ahead and rebid 2H after opening 1C and getting
- a 1S response? Then partner has S-K875 H-654 D-Q64 C-Q65, and a
- poor contract is reached because opener is not allowed to pass any
- simple rebid (2NT, 3C) by responder.
-
- Bad results are also common when opener has an extra-strong hand
- such as S-4 H-AQJ2 D-AK873 C-AQ10, with no safe way of showing it
- because jump reverses are played as splinter bids. The partnership
- may easily miss a slam or, to avoid that, get too high.
-
- There are three reasons for making a reverse forcing: (1) to avoid
- a jump raise with only three-card support; (2) to safely show
- three-card outside strength; and (3) to do away with space-
- consuming jump reverses while freeing those bids for another
- purpose (e.g., splinter bids).
-
- (1) can be satisfied by making a reverse forcing if responder's
- suit has five cards or more.
-
- (2) is not compelling, because you can usually jump in the original
- suit instead. With no secondary four-card suit, the first suit is
- probably a six-carder or very strong five-carder. Bidding three-
- card suits is a questionable practice anyway.
-
- (3) is also debatable, because jumps to show powerful hands (e.g.,
- strong jump takeout responses) send a message that simple forces
- do not. Splinter bids are still available (at one level higher)
- when jump reverses are natural.
-
- And why should a reverse promise another bid? With Fourth Suit
- Artificial (FSA - see previous chapter) available when responder
- has a good hand, there is no need to make all of her rebids
- forcing. Let's try a more playable approach:
-
- -- Opener can reverse with as little as 16 HCP with decent suits
- or three-card support for responder's major.
-
- -- Reverses are forcing only when responder's suit has five cards
- or more. Use the jump reverse to force. Responder may not pass a
- reverse with 3-3 in opener's suits, with which she must prefer the
- first suit. She generally passes only with four cards in the second
- suit, but a pass with 3-1 in the two suits is acceptable with a
- hopeless hand.
-
- -- Reverser can pass 2NT or a minimum return to his first suit,
- both of which show weakness, but jumps are forcing:
-
- Opener Responder
- 1C 1S
- 2H 2NT/3C - weak, not forcing
- 3S/4C - forcing
-
- -- Raise of reverser's second suit is forcing in hearts, invita-
- tional in diamonds:
-
- Opener Responder
- 1C 1S
- 2H 3H - forcing
-
- Opener Responder
- 1C 1S
- 2D 3D - invitational
-
- -- If responder's suit is a five-carder, she must bid the ranking
- suit as a forcing relay, but may pass opener's next bid. The relay
- is okay with a six-card suit provided responder is doubtful about
- game. With a better hand, either jump rebid with a six-card suit
- (if it is strong) or use FSA and then rebid the suit (both
- forcing). The relay is also permissible with a very strong four-
- card suit, possibly leading to a good 4-3 trump fit.
-
- Usually the ranking suit bid is responder's original suit, but not
- in one case:
-
- Opener Responder
- 1C 1S
- 2D 2H - showing five spades
-
- The partnership can stop at 2S if responder has a bad hand and
- opener has a minimum reverse with three spades. Since 2H is a
- relay, use 2S artificially for FSA in this sequence.
-
- After a relay opener can bid notrump, raise responder's suit, or
- otherwise clarify his hand, perhaps by jumping, perhaps by just
- rebidding his first suit minimally. If the relayer doesn't pass
- opener's rebid, her next bid may be passed if it is not encourag-
- ing:
-
- Opener Responder
- 1C 1S
- 2D 2H - showing five spades
- 2NT 3C/3D/3S - not forcing, weak
- 3H - forcing, probably 5-5
-
- When an eight-card major fit has been found, however, a bid in any
- other strain is forcing:
-
- Opener Responder
- 1C 1S
- 2D 2H - showing five spades
- 2S 3S - not forcing
- 2NT/3C/3D/3H - forcing
-
- Opener can pass the 3S bid if his reverse was a stretch: S-832
- H-AQ82 D-AKQ102 C-6. His 2S bid was not quite forcing. Because the
- bidding can stop in 2S, a light diamond-heart reverse is not out
- of line when holding three-card spade support. Don't go too far
- with this idea, because responder may have a weak hand and only
- four spades.
-
- -- With no convenient rebid, responder can use FSA. FSA denies
- exactly five cards in the original suit, but responder could have
- six provided she wants to be in game. FSA tends to deny a good
- notrump bid (maybe Axx or Qx, but not a better holding in the
- fourth suit). FSA at the two level does not promise another bid;
- responder may pass if opener bids minimally. If the FSA bidder does
- bid again, all non-game bids are forcing except a raise of opener's
- last bid:
-
- Opener Responder
- 1C 1H
- 2D 2S - FSA
- 2NT/3C 3D/3H/3S - forcing
-
- Responder could pass 2NT or 3C, bids that imply a minimum or near-
- minimum reverse. Responder's 3H bid shows a six-card suit, since
- she would relay with five. A raise of 3C to 4C would not be
- forcing.
-
- FSA at the three level (3C, perforce) promises another bid if
- opener does not bid game:
-
- Opener Responder
- 1D 1S
- 2H 3C - FSA
- 3D/3H/3S - forcing
-
- -- A jump to the three level in the fourth suit shows a real suit,
- not a splinter. This means you must bid notrump when the suit is
- clubs, because a jump to 4C is a splinter bid in support of
- opener's second suit (which would have to be hearts):
-
- Opener Responder
- 1D 1S
- 2H 3S - natural bid
-
- Opener Responder
- 1D 1S
- 2H 4C - splinter bid
