A Bit More Advanced Stuff – Roman Keycard Blackwood – 23 June 2010

Here for reference are the responses to 4NT when it’s Roman Keycard Blackwood. In RKCB the King of the agreed trump suit is counted as an Ace so there are in effect 5 (!) Aces. The responses to the 4NT ask enquiry are:
  • 5C = 0 or 3 Aces
  • 5D = 1 or 4 Aces
  • 5H = 2 or 5 Aces but no Queen of trumps
  • 5S = 2 or 5 Aces with the Queen of trumps

After partner responds 5C or 5D then the a bid of 5 of the next suit above (not the trump suit)ASKS for the Queen of trumps. The Queen is important because if you are missing an Ace you can’t afford to lose a trump trick as well so you suit better play for no losers, i.e. you need the Queen.

You show the Queen by jumping to 6 of the agreed suit or by bidding another suit which shows not only the Queen of trumps but an extra feature in the suit bid as well(King or singleton). If you don’t have the queen you “sign off” by simply bidding 5 of the trump suit.

K Q 7 6
K 7 5 4
Q 10 9 6 2
7

Partner opens 1S and you junp to 3S – a limit bid, 10 hcp but not mcuh quality to tee hand. [You also have seven ‘losers’ but no ace so devalue the hand a bit – 3S looks better than going game. Nonetheless partner now bids 4NT.

The bidding goes:

1S ..... - ... 3S
4NT.. - ... 5D
5H ... - ... 6H
6S

5D = One of five “key cards”, in this case the King of Spades.
5H = “Do you have the Queen of Spades?”
6H = “Yes, I do and the King of Hearts as well”
6S = “Thanks for the info, but 6S is enough, we don’t have seven!”

The Weird World of Cue Bids - 29 Oct. 2009

I often get asked “So exactly what is a cue-bid?” So, here’s a little run-down of some of the more normal uses of the cue-bid with a short explanation.

To be totally honest with you there are lots of different forms of cue-bids which all have exotic names but I’m not going down that convoluted garden path. Normally when you make a bid it's:
  • (a) a suit you have, and
  • (b) is at least 4 cards long.
A cue bid is a bid in a suit that you DON'T necessarily have. Weird, huh? As we’ll see a cue bid can be in a suit you don't have any of AT ALL! Dangerous stuff, I know. So, I hear you shout “how do we know it’s a cue bid and not a real suit?” Well start with the obvious one:

Cue Bidding The Opponent's Suit (Also Known As: “Fit-Showing Cue Bids”)

When partner bids a suit, and your right hand opponent (RHO) overcalls, how can you tell partner the difference between a hand that just wants to get in the way and a hand that has some genuine support and strength?

1S - 2C - ?

1) xxxxx ..............................2) KJxx
... QJx .................................... KQx
... Kxxx .................................. Kxxx
... x ......................................... xx


On the first hand you want to raise the level of the bidding with a pre-empt so as to mess up the opponent's attack, so you bid 3S, weak but supportive. Fine. But next time you get the same auction you are lumbered with hand 2). This time you want to raise partner because you have points and support - so can you bid 3S? Ah, No. ’Fraid not. We just said that 3S was going to be used as a pre-emptive manoeuvre for hand 1), didn’t we? so how can we tell partner the difference?

You’ve seen it coming, I know you have... yes it’s a cue bid of the opponent’s suit - 3C!! Here is a situation where the opponent’s bid, far from making your life difficult, has actually increased your options: you can turn their intervention to your own benefit. In this way when they venture into the auction’s murky waters, the opponents in effect create for you a handy stepping stone that was not previously there.

This “stepping stone” principle has many uses:

“Control Asking Cue Bids”

1D - 1H - 2H?

In this auction your 2H cue-bid not only tells partner you have values (probably 10+) but also asks if partner can stop the hearts suit well enough to bid No Trumps. Now the stepping stone is practically a full-blown bridge with 2-way traffic: you just told partner something AND asked a question all in one bid. 2H could mean a number of things but it is FORCING and asks partner to explain their hand further.

Clearly, in these situations when you bid the opponent’s suit, it’s a suit in all probability you don’t have. But it’s nevertheless a bid packed with extra illumination and intent like an information super highway. It also has the added value of freeing up all the direct raises of partner’s suit (1S - ? - 2/3/4S) as annoying defensive measures designed to clog up the opponents’ exchange and force them down an information cul-de-sac.

There’s more....

“Control Showing Cue Bids”

1S -PASS - 3S - PASS
4C?

Why is partner suddenly bidding this Club suit? Has partner pulled out the wrong card? Is partner having a stroke? We’ve agreed spades. So why doesn’t partner just bid game or slam or whatever? Unless ..... it’s a cue-bid!

This time there’s no opposition bidding but now partner wants to tell you something more. A trump suit has been agreed and a new suit has been introduced below game level. What’s the message? The only reason for this bid is that partner has sights set on the possibility of a slam and is giving you information in the hope that you can reciprocate; it’s a control showing cue bid ie thpartner is saying I have “control” of the club suit, that is to say the ace of clubs. The hand could be something like

AKxxxx ................ QJxx
Ax ........................ Kxx
Kxxx .................... AJxx
A .......................... xx

Now, if you’re lucky enough to hold the ace of diamonds, you can cue-bid that as well and suddenly slam looks a pretty good prospect and the auction could go something like:

1S .............. 3S
4C ............. 4D
4H ............. 5H
6S

4C, 4D & 4H all show first round control of the suits mentioned (i.e. aces or voids) while, as the ace has already been shown, 5H must be a second round control (ie king or singleton). So just as you can get quite specific about not only the number of points in a hand or the length of a particular suit, you can also tell partner about specific individual cards (normally only once a suit has been agreed, so be careful!)

The other basic thing to remember about all these Cue bids is that they are unconditionally forcing. That is, partner CANNOT pass. Under any circumstances. Whatever they’ve got. Whoever they are. Claiming to be of royal descent will not suffice. Remember the graffiti in the 3rd level dungeon at the Tower of London? It says it all:

Who passeth fawcing byd
soonest be sans hyd


As AJP Taylor so memorably said in his book Really Bad Mistakes by Royalty: “Without that erroneous PASS, the Queen would have lived; our Nation’s history radically altered.”

Those who yearn for more rarified stuff can look up Michaels Cue-bids, Fourth Suit Forcing cue bids, Western Cue bids, Eastern Cue bids, and that old favourite - Invisible cue bids. (I promise you these all exist!)

Enjoy!
