CUE BIDS BY RESPONDER
On the First Round
There are two situations:
1) When a new major suit response would not be forcing ("negative
free bid" in negative double situations), the cue bid discussion
in chapter NEGATIVE DOUBLES OF SIMPLE OVERCALLS in the book
"Conventional Doubles" applies.
2) Otherwise, a first round cue bid response to a minor opening is
always very strong, as is a two-level cue bid response to a major:
South West North
1C 1D 2D
1H 1S 2S
These cue bids are game forcing. They show very good trump support
for opener's suit plus first round control of the opposing suit
(preferably a void or singleton ace). They tend to deny a good suit
in the unbid major(s).
A notrump rebid by opener implies that he has secondary strength
in the opposing suit, and that he would not have opened the bidding
without that strength. The notrump bid warns of dangerous dupli-
cation, and should be avoided if the secondary strength in the
opposing suit is extra strength.
As a corollary, failure to bid notrump implies that the hand is
not dangerously duplicated. This means that opener must sometimes
bid notrump with a six card suit and a singleton in an unbid suit.
After opening 1C with S-A42 H-KQJ D-4 C-Q108743, if LHO bids 1H and
partner cue bids 2H, this hand should rebid 2NT to warn of the
duplication. A 3C rebid implies that the hand would have been
opened regardless of any secondary heart strength.
If opener has a balanced minimum and a double stopper in the cue
bid suit, he can jump to 3NT after the cue bid. There is no need
to jump with a good hand, because the cue bid is forcing to game.
A three-level cue bid response to a major opening merely shows a
strong raise to game in opener's major. It does not say anything
about control of the opposing suit. A splinter bid is available
when the opposing suit is controlled (Jump cue bid responses are
splinter bids):
South West North
1S 2C 3S - limit raise
3C - game raise in spades
4C - splinter bid
4S - preemptive game raise
On the Second Round
When a player cue bids on the second round, after failing to
respond on the first round, the bid is natural:
South West North East
1C 1H Pass Pass
2C Pass 2H - natural bid, non-forcing
North has hearts that are good enough to play opposite a singleton,
despite West's overcall (and West's bid may have been a psych). He
was hoping South would reopen with a double, which of course he
would have passed. The 2H bid is not particularly strong, and South
will generally pass.
Other cue bids by responder are discussed in chapters GAME TRY CUE
BIDS and SLAM TRY CUE BIDS. Cue bids in response to an opening
notrump bid are covered in the book "Notrump Bidding" and those in
response to a notrump overcall in the book "Defensive Bidding." Cue
bids in response to a reopening 1NT overcall have the same meaning
as the bid would have if partner had opened 1NT (i.e., the opening
bid is ignored).
Passed Hand Cue Bid Response
A passed hand's cue bid response also shows first round control,
but is forcing to a limit situation only. It can be based on
various sorts of good hand with which responder doesn't want to
risk opener's passing of a new suit response or negative double.
South West North East
-- -- Pass Pass
1C 1D 2D
North has S-Q9763 H-K1032 D- void C-AQ65. Thanks to the cue bid,
his spade bid on the next round will be forcing.
