INVITATIONAL CUE BID 

by Yvonne Cains
Invitational Cue Quiz

One of the most important applications for cue bids is to show a good raise for partner"s overcalled suit. It promises at least LIMIT RAISE VALUES 10+ pts support or an OPENING HAND + own suit. When you have support for partner you should show it as fast as you can.
 
You hold:

K1072

1D – 1S – 2D – 2S

2S shows 6-9 pts (colour = opp bids)

KJ42
Q843

10972

 1D – 1S – 2D – 3S

3S shows a pre-emptive raise – weak hand with shortage and 4 trumps

K84
AQ32
53
K1072

 1D – 1S – 2D – 3D 3D (invitational cue)

You may have a limit raise for partner or an opening hand with your own suit.
 Note: a passed hand cue always promises a limit raise,

JUMP CUE

1D – 1S – P – 3D

K763

K1072

Jump cue shows 4 card support and at least a limit raise.

K763

K1072

1D – 1S – P – 2D – P- 2S - P - 3H

2D here shows an opening hand + own suit.
When partner rebids 2S to show a minimum overcall, the 3H bid
shows an opening hand and is forcing for one round.

REBIDS BY OVERCALLER

After the invitational cue bid the overcaller must not pass unless his RHO bids or doubles – in which case he may pass without something useful to say.
1H – 1S – P – 2H – P - 2S

KJ875
963
KQ109

Your natural bid is 3D but that requires extra strength so rebid 2S to show a minimum overcall.
Any rebid below your original suit is ambiguous in strength e.g.

AQ1086
K1093
84
103

1D – 1S – P – 2D – P - 2H

Even though your overcall is minimum, it is possible to show your heart suit below 2S.  Any rebid beyond your original suit shows an opening hand e.g.

KQ976
AQ7
K8
985

1H – 1S – P – 2H – P - 2NT

By bidding past 2S, 2NT shows extra values.

REBIDS BY THE CUE BIDDER

1C – 1S – P – 2C – P - 2H – P - 2S

A new suit after a cue shows at least 13 hcp and a 5 card or longer suit. This is forcing for one round. e.g.

AK984
A3
K1076
97

1C – 1H – P – 2C – P – 2H - P - 2S  

Here you show 5 spades and an opening hand partner must bid again.

OTHER RESPONSES TO OVERCALLS

83
KQJ84
743
A107

1C – 1S – P – 2H

Opening may pass but with a good hand and support can raise .

A97
93
AQJ1087
93

1C – 1H – P – 3D

The jump to 3D denies heart support and invites to game – possibly NT if opener holds stopper in club suit.

97
AK10972
A45
108

1C – 1D – P– 2H

2H invites game in hearts and is non-forcing.

ALL NT BIDS retain their usual meanings:

a) INT shows 8-11hcp
b) 2NT shows 12-14 hcp after a 1 level overcall
and 9-11 hcp over a 2 level overcall
c) 3NT shows 15+ hcp and a source of
tricks

INVITATIONAL CUE IN COMPETITION

If RHO bids or makes a negative double the principle of the cue bid and its related responses are still in effect. The level of bidding may sometimes be higher but it still pays to follow the structure whenever possible.

KJ7

1043
AQ854

1D – 1S – 2D – 3D

You show a good 10-12 pt spade raise. With a minimum partner must bid 3S in which case game will be avoided. Had you instead jumped to 3S that would be pre-emptive.

87
A754
KJ75
QJ4

1H – 2D – X (neg) – 2H

Here your cue bid guarantees a diamond fit. Without diamond support you would REDOUBLE to show a good hand.

If your RHO bids a new suit you have a choice of cue bids. You cue the suit in which you are STRONGER. Partner can then judge the usefulness of any honours he holds in that suit. He may even bid NT, especially if the overcall was in a minor suit.

Q1083

1C – 1D – 1S – 2S
You chose to cue 2S indicating strength in that suit. Partner may now bid NT without a spade stopper.

THE INVITATIONAL CUE IS ONE OF THE MOST USEFUL CONVENTIONS IN COMPETITIVE BIDDING.
ONCE YOUR PARTNERSHIP ADOPTS THIS CONVENTION YOU WILL HAVE THE BENEFIT OF GREATER ACCURACY IN COMPETITIVE SITUATIONS.
