Multi-Cues : Facts
(Also known as "control bids")
- After a trump suit has been agreed and the bidding is
forced to the Game level (usually at the 4-level)
the bid of a new suit is a multi-cue bid.
- A multi-cue bid shows 1st or 2nd round control in the suit bid
an Ace or a King or a Void or a Singleton
- Multi-cues are not shown for the agreed trump
- Multi-cues are bid up-the-line, skipping a suit
denies a control in that suit.
After a player has skipped a suit, Partner only makes another
multi-cue bid when he also holds 1st or 2nd round control in the
skipped suit. If not he signs off in the trump suit.
- With no more controls to show sign off in the trump suit.
Multi-cues may be followed by Blackwood (or RKC Blackwood) to
check on the Aces.
- After a trump agreement in a minor suit a new bid
below 3NT is not a cue bid, it merely shows a
stopper for a possible 3NT contract.
- 3♣ - (= stopper)
Roman Keycards Blackwood
RKC Blackwood is especially effective after a Multi-Cues bidding sequence.
- RKC replies are used after 3NT or 4NT Blackwood, Minorwood and Voidwood.
- There are 5 keycards : the 4 Aces plus the Trump King.
The Trump Queen can also be shown.
- RKC replies are:
- Step 1 = 1 or 4 keycards (Note : 1430)
- Step 2 = 0 or 3 keycards
Step 3 = 2 keycards without the trump Queen
Step 4 = 2 keycards with the trump Queen
- For example :
- After - 3♥ - - ?
- 4♣ = 1 or 4 kaycards
- 4♦ = 0 or 3 keycards
- 4♥ = 2 keycards without the Q♥
- 4♠ = 2 keycards with the Q♥
After - 3♦ - - ?
- 4♥ = 1 or 4 keycards
- 4♠ = 0 or 3 keycards
- 4NT = without the Q♥
- 5♣ = 2 keycards with the Q♥
After a Step 1 or Step 2 reply, the cheapest bid, except for the trump suit, asks for the Trump Queen.
- Next step = "I don't have the trump Queen"
- Following step = "I do have the trump Queen"
- Asking for Kings is the same as for standard Blackwood, but the trump King is not counted.
