(584) Exclusion Keycard

When we are interested in slam in a suit contract but have a void in one of the side suits, it adds some complexity to our slam bidding.  We may be able to make a slam missing two Aces (or a grand slam missing an Ace), if partner does not have the Ace opposite our void.  When exploring slam, we want to know if partner has that Ace or has the “good Aces”, the ones opposite our losers.  One way that we find out about the location of partner’s Aces is by using control showing bids. This is especially effective if we use them to show first round control (if we play that our control showing bids could be 1st or 2nd round, then we know less about which Aces partner hold).  There is a gadget that we can use in some auctions that allows us to try to solve this problem.  This convention, called Exclusion Keycard, asks partner for their number of Keycards (or Aces if we play Blackwood), excluding one particular Ace – the place where we are void. This Exclusion allows us to find out if partner has enough of the “right Aces” for us to make slam.

(583) Problems with Kickback Keycard

Kickback is a convention that can make slam bidding easier, in that it gives us more space to ask partner for the Queen of trump, but it can also cause problems for us in the bidding.  Any time we make a game contract (like 4♥ or 4♠) a conventional bid, there is danger that we have an expensive mixup with partner.  Here we look at some classic danger auctions that may come up if we choose to play Kickback and then discuss some of the common partnership agreements or philosophies for how to handle these dangerous auctions.

(578) Preempt Keycard

When we preempts the bidding they cannot have 3 or 4 keycards. So it does not make sense to have a keycard system that shows these. Here we look at an improvement in steps and in how we ask.

(577) Jump Shift Structure

When Opener makes a jump shift into a new suit with their second bid, it is a strong bid that creates a game forcing auction. This is a good bid because it ensures we reach game, but it is a bad bid because it eats up a lot of bidding space without fully describing our distribution. This is a problem. One of the most difficult opening hands to describe to partner is the unbalanced single-suited (one 6+card suit) hand with 18-19 HCP.  This is one of the strongest hands that does not open the bidding 2♣.  With this hand we usually open our suit at the 1-level and after partner responds at the 1-level, we lie in a minor suit.  If our one suit is a Major, then we show our strength by making a jump shift into 3♣, even when we have very few ♣ (as few as 2 cards.)  With this bid we create a game forcing auction (showing our values), but we distort our shape (partner expects that we have at least 4 cards in the ♣ suit). This can cause some confusion with partner if they have a large fit for our ♣ suit.  We would like to have a way to let partner know that this jump shift is done on a single-suited hand, not on a two-suited hand.  Let’s look at a system that helps us improve our jump shift methods.

(576) Kokish Over Strong 2C

Balanced hand bidding is relatively easy. We can usually describe our hand to partner by opening 1NT or rebidding 1NT. This lets partner know both our points and our hand type with either our first bid (when we open 1NT, the best situation) or with our second bid (when we rebid 1NT).  However, if we have a big balanced hand then we need to have tools for describing our hand as well.  These usually involve the use of 2NT – as a rebid, an opening bid, or even a rebid after having opened the bidding 2♣.  But this does not solve all our bidding problems when we have these large balanced hands.  Let’s look at these auctions in detail, see some of the issues, and then look at a useful gadget called Kokish to help us bid better.

(582) Kickback Keycard Ask

(582) Kickback Keycard Ask

One of our most commonly used tools for determining if we should bid slam or not is Keycard Blackwood. The most popular version of this is 1430 Keycard. This tool allows us to exchange a lot of useful information with partner.  We attempt to determine how many of the 5 Keycards we have, plus we also hope to be able to determine if we have the Queen of the trump suit. When ♠ is the trump suit, then we have plenty of bidding space to communicate, but when lower-ranking suits are the trump suit, using 4NT to ask for Keycards leaves us little room to exchange information without getting the auction too high.  To fix this problem, some partnerships use Minorwood for their minor suit Keycard auctions, but this does not solve our problem in the ♥ suit. There is another approach, called Kickback, that tries to solve this problem. Let’s see how this works.

(581) More Specific Kings

(581) More Specific Kings

In an Ace-asking auction, when we make the follow-up bid to ask partner about their Kings, we usually do so to investigate a grand slam (though some partnerships do this in order to determine if 6NT is good contract).  Most partnerships start with the agreement that they answer this question by showing their number of Kings.  But sometimes, a Grand Slam is not about partner having 2 or 3 Kings, but about them having the right single King.  This “right King” is often the one opposite our long suit – allowing us to produce a large number of tricks.  To get this information, many partnerships evolved their King-showing methods from “number of Kings” to “Specific Kings.”  Here we look at how we can use Specific Kings in a variety of our Ace-asking auctions.

(580) More Queen Asks

When we move from playing Blackwood to Keycard Blackwood, we improve our slam bidding by including a discussion of the trump King and Queen.  Playing Keycards (let’s say 1430), then partner’s answer to our 4NT ask sometimes tells us if they hold the trump Queen and other times does not.  In the latter case we need to be able to ask partner if they hold the trump Queen, as we do not want to bid a slam missing a Keycard and the trump Queen.  Let’s look at how we ask partner about the trump Queen in a variety of different auctions.
