CUE BIDS BY OPENER
Partner Has Responded in a Suit
South West North East
1C 1H 1S Pass
2H - game forcing
This cue bid has traditionally shown no losers in the opposing suit
and terrific support for responder's suit. Today that is what we
would like to have, but the modern meaning of the cue bid is much
less precise. All that responder can tell at this point is that
opener wants to be in game, at least.
Responder must now make the most helpful bid he can find, which is
likely to be notrump if he has the opposing suit stopped. With a
double stop and a poor hand, he can jump to 3NT. This will warn
opener that there may be serious duplication (strength opposite a
void), and that responder is weak.
In the auction above, South could have any of the following hands:
1) S-AQ32 H-void D-K1083 C-AKJ94 (the traditional hand)
2) S-A4 H-32 D-KQ C-AKQJ976 (too good for a 3C rebid)
3) S-AJ3 H-4 D-AJ4 C-AKQ874 (ditto)
4) S-A54 H-87 D-KQJ C-AKQJ4
With hand 1) opener will follow up with a leap to 4S or a repeat
of the cue bid. Bidding in this fashion shows the old-fashioned
sort of cue bid. With hand 2) opener will rebid clubs on the next
round, implying this sort of hand. With a weaker hand he would
prefer a 3C jump rebid, so this sequence is very strong. With
hand 3) opener will raise spades on the next round, feeling his way
to the proper contract. He will do the same with hand 4). There is
no need to do any jumping with hands 2), 3), and 4), because the
cue bid is forcing to game.
Partner Has Made a Negative Double
South West North East
1C 1S Dbl Pass
2S - forcing to a limit situation
If North bids 2NT in response to the cue bid, that is a limit
situation. A 2NT response to a cue bid is not forcing if the hand
opposite has previously acted, and a double is an "act." Any other
non-game bid by North would be forcing. See chapter CUE BIDS IN
NEGATIVE DOUBLE SITUATIONS.

South cannot be making game forces after only opening one of a suit
and not getting a response, but the above cue bids show a very
strong hand and are forcing to a limit situation. Opener could have
four card support for both unbid suits (SAK87 H-void D-A1098
C-AK1097), or a long strong suit with some support for one or both
unbid suits (SAJ3 H-void D-Q107 C-AKQJ873).
Such cue bids almost guarantee a void. Otherwise it is difficult
to give opener a hand that is unsuitable for a takeout double. The
implication is that opener would not relish a leave-in of a takeout
double, and this implication strongly suggests a void.
Responder must now bid the full value of her hand, for if she makes
a minimum bid the "limit situation" has been reached and opener
could pass.
Additional cue bids by opener are covered in chapters CUB BIDS IN
TAKEOUT DOUBLE SITUATIONS, SLAM TRY CUE BIDS, and COMPETITIVE CUE
BIDS.
