- Cheapest cue bid is made.
- Cue aces first, kings second. On occasions, especially if you are known to be weak, it is necessary to cue a second round control before first round control in that suit has been shown or denied.
- Below game, return a cue only if slam appears possible - with a poor minimum return to the trump suit. If partner cues again, or cues above game you must return the cue if possible.
- To cue above five of the trump suit is a try for seven.
- If either partner is able to judge the correct final contract he should bid it as soon as possible.
- If a cue bid is doubled, redouble shows second round control of that suit, to pass is neutral conveying some interest.
- 5C = no ace.
- 5D/H/S/NT = ace of this suit.
- 6C = two aces.
Grand Slam Force
5NT is only GSF if a JUMP to 5NT has been made. After a 2C opening. GSF is the preferred meaning over a trump asking bid.
- holding none of the top three honours, sign off in 6 of the trump suit.
- holding 2 of the top three honours bid 6NT.
- holding all 3 top honours bid 7C. Both 6NT and 7C allow partner to correct.
If there is space available between 5NT and 6 of the trump suit show the
following in order:
- One of the top three.
- One of the top two plus an extra undisclosed trump.
- One of the top two plus two extra undisclosed trumps.
A direct raise of an agreed major to the 5-level shows interest in
six, but suggest trump weakness. Partner should accept IF his own
trumps are strong.
When there is exactly one unbid suit (or when the opponents have bid
exactly one suit) when it means bid six if you can control the unbid
- When a suit is agreed or a JUMP to 4NT agrees a suit, 4NT is KCB.
- ANY JUMP to 4NT is BW, the jump agreeing the last naturally bid suit.
- 4NT is NOT BW if the 4NT bidder has cue-bid or if 4NT could have "sensibly" been bid at an earlier opportunity as BW.
- 4NT is BW if it is bid at the first opportunity after a suit has been agreed.
Responses to KCB
- 5C = 0 or 3 key cards.
- 5D = 1 or 4 key cards.
- 5H = 2 key cards without the trump queen.
- 5S = 2 key cards with the trump queen.
- 5NT = 2 key cards with a void. A bid of 6 suit then asks responder to bid seven with a void in that suit.
- 6 suit ranked below trumps = 1 key card with void in bid suit.
- 6 trumps = 1 key card with void in suit ranked above trumps.
- After 5C or 5D, the cheapest non-trump bid (ie step) asks for trump
queen. Without the Q rebid in trump suit, with the Q cue a feature (ie a K
or maybe a Q in one of partner's suits). After asking for the trump Q, a bid
of 5NT asks responder to bid a feature.
- 5NT over a direct response of 5C/D/H/S asks for kings.
egs. 1S : 4S 1S : 2D
4NT : 5C 4NT = KCB in Diamonds.
5D : 5S
5NT = bid a feature. 1NT : 4NT = non forcing BW
1S : 2S
3H : 4S
4NT = KCB in Spades. 3H not a cue but a "game try".
