CUE BID RESPONSES TO OVERCALLS
Most cue bid responses to overcalls are discussed in chapter
COMPETITIVE CUE BIDS. Also see chapters RESPONDING TO SIMPLE
OVERCALLS and NOTRUMP OVERCALLS in the book "Defensive Bidding."
Jump Cue Bid Response to a Major Suit Overcall
South West North East
1C 1S Pass 3C
1S 2H Pass 3S
These single jumps in opener's suit are "mixed raises," showing
good trump support for partner's suit and some defensive strength.
East is too strong to simply raise directly to the three or four
level, actions that tend to be based more on distribution than on
high cards. The trump support should be at least four long; with
fewer trumps a simple cue bid is preferable. The overcaller can
count on some defense when deciding whether to double the op-
ponents.
In the first auction, West should assume that East has good values
for a raise to 3S, with four-card support. If that is enough for
game, he should bid it. If West just bids 3S, East may well pass.
In the second auction, East definitely has enough for game, but
wants to show good trumps and some outside high cards. West may
even be able to bid a slam on the basis of this information. At
least he will have a better idea of what to do if opener bids
again.
Jump Cue Bid in Response to a Minor Suit Overcall
South West North East
1C 1D Pass 3C
1S 2C Pass 3S
This cue bid response strongly urges the overcaller to bid 3NT if
he has the opposing suit stopped. The cue bidder has a super fit
in the minor suit plus quick tricks outside. The hand is so good
that a simple cue bid, which may not have both fit and outside
tricks, is not sufficient.
When Both Opponents Bid
If RHO comes in with a raise over an overcall, a cue bid serves to
distinguish a strong jump raise from a weaker jump raise:
South West North East
1H 1S 2H 3H
This simple cue bid of a raised suit shows a strong raise of the
overcall, as opposed to a more preemptive sort of raise. If West
has extra values for the overcall, she can bid game. If South now
bids 4H, West should not be too quick to bid 4S unless she thinks
she can make it, because the cue bid shows good defensive potential
in addition to trump support.
If RHO comes in with a new suit, the strong raise is shown by a
cue bid of responder's suit, while a bid of opener's suit is
natural, showing the suit:
South West North East
1C 1D 1H 2H - strong diamond raise
3D - weak diamond raise
2C - good club suit
Remember that the "strong raise" cue bid applies only over a new
suit bid or a raise, not over a pass or negative double. See
chapter COMPETITIVE CUE BIDS.
If RHO responds 1NT, advancer would double with a strong raise. A
bid of opener's suit is natural:
South West North East
1H 1S 1NT 2H - natural, long hearts
East has long solid hearts and not much in high cards: S-42
